I tend to drive old cars, so the first time I saw the puddle, I assumed the worst — an oil leak and expensive repairs. When I checked, though, it was just water. Then I remembered the air conditioner. All ACs produce water, and your car’s just drips it onto the road.

Window air conditioners, however, feature drainage systems that direct the water outside. A faulty drainage system is usually the culprit when the unit leaks onto the windowsill or the floor.

Most of the time, you can fix drainage problems yourself. Dripping can also result from frozen evaporator coils — usually an easy fix. If you have an older unit, it may be running low on refrigerant, and recharging it might cost as much as a new air conditioner.

What Causes an AC to Leak Water Inside?

An air conditioner circulates warm air past a set of evaporator coils, which cools it. Since cool air holds less moisture than warm air, the excess condenses and turns to water. It’s basically the same process that makes rain.

Some units direct the water through a tube to the outer part of the housing. In others, the blower slings the water against the compressor to cool it. In both cases, the water eventually drips into a pan at the bottom.

If water is dripping from an AC unit indoors, the reason may be one of the following:

• A blocked drainage tube: Dust from the air can mix with water and create an obstruction.
• A damaged drain pan or blocked water outlet: A damaged pan produces drips in all the wrong places, and a blocked water outlet causes an overflow.
• The drain pan tilts the wrong way: It needs to tilt toward the outside. Some window AC units give the pan this tilt when the unit is installed level. Units without this feature must be tilted during installation. If the unit wasn’t leveled properly, it’s probably been leaking since Day One.
• A dirty air filter: This prevents air from circulating freely around the evaporator coils, and the refrigerant can’t absorb the heat. That makes the coils ice over and drip water when the unit isn’t running.
• There’s a refrigerant leak: This can also cause the coils to ice over and drip when the unit is off. It requires professional repair.

What’s the First Thing To Do if an AC Is Leaking Water?

Turn the air conditioner off and wipe any water off the floor. Open the grille on the front and, if necessary, remove the air filter and look for ice on the evaporator coils.

If the coils are iced over, leave the unit off to melt the ice and put a bucket underneath to catch the water. If that’s not the issue, leave the air conditioner off while you troubleshoot. Better yet, unplug it.

How To Fix an AC Leaking Water Inside

Some window air conditioner fixes require access to the outdoor part of the unit. That can be challenging if it’s mounted in an upper-story window, or in a tall building. If you can’t reach it through the window, you might need to bring it inside. If you’re not up for that, call a pro.

Tools and materials

• Kitchen sponge;
• Screwdriver;
• Epoxy putty;
• Torpedo level;
• Shims.

Clean or replace the air filter

If you see ice, cleaning or replacing the air filter may solve the problem. Most filters are cleanable.

If so, run water through it from the faucet while you scrub out the dirt with a sponge. Let the filter dry while the ice on the coils melts, then put it back in and start the unit. If the coils ice over again, call a service tech to recharge the refrigerant.

Clear the drain hole

The drain pan for a window unit has a hole in one of the outside corners, which may be plugged. To access it, pull back or remove the skirting from one side of the unit and reach through the opening. Remove any loose debris and poke a screwdriver through the hole to open it up.

Patch or replace the drain pan

If you have an older AC and you see water dripping from any part of the drain pan, the pan’s probably rusted and you may have to replace it. If there’s just one hole and you can reach it, you can try to patch it with epoxy putty.

Clean the drain tube

The drain tube leading from the evaporator coils to the outside of the housing may be blocked. Check your owner’s manual to find where this is and clean it with a long, thin object like a sewing needle.

You may need to remove the outside housing cover to do this. If the air conditioner is mounted in a high window, open the window far enough to reach the cover or take the unit indoors.

Adjust the tilt

If a newly installed window air conditioner leaks onto the floor, it’s probably not tilted enough toward the outside.

Before you adjust it, check the manual to see if the pan is installed inside the unit at the proper angle. In that case, the air conditioner should be sitting dead-level in the window. Otherwise, it should tilt downward toward the outside.

Use a torpedo level to check it. If the AC needs to tilt outward, shim up the front with thin pieces of wood or plastic until a quarter of the bubble passes the centering line.

Non-grounding-type receptacles are called that because they lack a third prong for grounding electrical equipment, appliances and tools. Grounding is important to protect against electric shocks; the third line redirects electric current during a hazardous ground-fault condition in an appliance.

Attempting to plug three-prong appliance and equipment cords into old two-prong receptacles can be a serious electrical hazard and probably violates the manufacturer’s warranty.

The National Electrical Code (NEC) generally does not apply retroactively, so you’re not obligated to replace non-grounding-type receptacles. However, if you do replace them, the new ones must be grounded to conform to the NEC.

Replacing old receptacles used to be simple. But now, like many things, it’s more complicated. The good news is, there are multiple viable options.

Grounding-Type Receptacle Replacement

Where a grounding means exists in the receptacle box, three-prong grounding-type receptacles must be installed as replacements. The green grounding terminal on the receptacle must be connected to the grounding means. The grounding means might be a grounded metal box, or a bare or green copper equipment grounding wire in the box.

With some basic testing, you should be able to determine if a grounding means exists.

Non-Grounding-Type Receptacle Replacement

Where a grounding means does NOT exist in the receptacle box, you have a few options:

Replace with another non-grounding-type receptacle

• Non-grounding-type receptacles are still manufactured in limited quantities, so you can replace a broken one with a new one. It doesn’t enhance electrical safety, but allows you to make a necessary repair in a pinch.
• Don’t use three-prong adapters with two-prong plugs. If not installed properly, they can be a serious safety hazard.

Replace with a ground-fault circuit-interrupter (GFCI) receptacle

• This significantly improves safety. You won’t have a grounding means for your appliances, but the GFCI provides shock protection by tripping and stopping the flow of electricity during a ground-fault condition.

• If you select this option, the receptacle or cover plate must be labeled “No Equipment Ground.” The labels are included in the package when you buy the GFCI receptacle.

Replace with a grounding-type receptacle

• If you have a branch circuit with a series of daisy-chained receptacles around a room, you can install a GFCI receptacle in the first receptacle box as mentioned above, then install standard grounding-type receptacles in the downstream receptacle boxes. Say you have a branch circuit that supplies four receptacles in one bedroom, then it jumps over to supply four receptacles in another bedroom. You only need one GFCI in the first receptacle box on that circuit in the first bedroom, and seven standard receptacles in the remaining downstream boxes on that circuit.
• The GFCI receptacle must be labeled “No Equipment Ground,” and the other downstream standard grounding-type receptacles or their cover plates must be labeled “GFCI Protected” and “No Equipment Ground.” These labels are provided by the manufacturer when you buy the GFCI receptacle.

Are There Other Code Requirements When Replacing Receptacles?

In recent years, the NEC added new rules for replacement receptacles. These are applicable to any type of existing receptacle you replace, two-prong or three-prong.

Ground-fault circuit-interrupter protection (GFCI)

GFCI technology protects people from lethal shocks. If you replace an existing two-prong or three-prong receptacle at a location that must otherwise have GFCI protection in the current NEC — say, next to your bathroom sink — you need to provide GFCI protection.

Arc-fault circuit-interrupter protection (AFCI)

AFCI technology protects people and property from fire hazards. If you replace an existing two- or three-prong receptacle at a location that must otherwise have AFCI protection in the current NEC, like in a bedroom model, you need to provide AFCI protection. Best to install an AFCI circuit breaker at your main panel.

Tamper-resistant receptacles (TR)

A tamper-resistant receptacle has built-in shutters to prevent young children from inserting foreign objects into the receptacle. When replacing existing receptacle outlets, all replacement receptacles must be tamper-resistant.

Weather-resistant receptacles (WR)

Weather-resistant receptacles feature corrosion-resistant components. When properly installed in a weatherproof enclosure, they provide extra durable protection from rain, snow, ice and moisture.

If you replace an existing receptacle at a location that otherwise requires weather-resistant receptacles in the current NEC, the replacement receptacles must be weather-resistant. So if you replace an old outdoor GFCI receptacle, then the replacement GFCI receptacle needs to be marked WR.

Learn the Anatomy of a Central Home Air Conditioner

Central home air conditioner service systems consist of two major components: a condenser that sits outside your house and the evaporator coil (often referred to as an A-coil) that sits in the plenum of your furnace or air handler. The refrigerant in the A-coil picks up the heat from your home and moves it to the outdoor condensing unit. The condensing unit fan blows outside air through the condensing coil to remove the heat. The condensing unit houses the three parts replaceable by a DIYer: the AC contactor, the start/run capacitor(s) and the condenser fan motor. The condensing unit also houses the compressor, but only a pro can replace that. The A-coil has no parts that can be serviced by a DIYer.

It worked. And if I had trees, bushes and flowers to water, it would have been twice as useful. Plant watering is the main reason why more homeowners are looking into installing grey water systems.

“What a waste it is to flush toilets with such a precious resource as clean drinking water,” says Lauren Anderson, academy director at Earthship Biotecture in New Mexico.

Earthship’s headquarters, in the desert, only gets around seven inches of rain a year. But all the houses in that neighborhood have such sophisticated rain capture and grey water systems that residents grow their own produce and rarely need supplemental water from wells.

For those of us in standard houses, installing a grey water system can still make a big difference. Households can reuse around two-thirds of their indoor water on outdoor irrigation. Considering outdoor use makes up between 30% and 70% of our water bills, that can save money, plus upwards of 40,000 gallons of water a year.

What Is Grey Water?

Grey water is wastewater from showers, baths, washing machines and bathroom sinks. It should not be confused with black water, aka wastewater from the toilet. Some states consider water from kitchen sinks and dishwashers to be black water, while others don’t.

Regardless of where you live, kitchen water contains higher levels of grease and organic material than other sources of grey water.

What Can You Use Grey Water For?

Grey water is most commonly used for outdoor irrigation.

“Simple systems take unfiltered grey water and distribute it to larger plants, like trees and bushes,” says Laura Allen, the cofounder of Greywater Action. Her group teaches people how to design and install grey water irrigation systems.

Other types of systems filter the water so it can be distributed by a special drip irrigation system. More complex systems can filter the water to flush toilets.

Is Grey Water Dangerous?

No. With basic health and safety precautions, grey water is safe to use.

Because it could carry bacteria and viruses and chemicals left over from your laundry, you should never drink it, or allow anyone to touch it. Don’t use it on root vegetables, and don’t let it touch the edible portion of any food plant. It should also never be sprayed or allowed to pool up, run off the property or run too close to a waterway.

What Is a Grey Water System?

One that allows you to direct grey water to the landscape or toilet for reuse, back to a septic tank, or down the city water drain.

Some grey water systems rely on gravity to move the water outside. Others employ a small tank with a pump inside to push water uphill or across a flat landscape. Many systems use a natural mulch filter in the landscape to catch hair and debris before the water soaks into the soil. Others feature an external filter you must clean by hand.

“The system is a pass through,” says Remy Sabiani, owner of Water Wise Group. “You’re going to take a shower and pretty much at the same time you’re going to water your plants. You’re going to do a load of laundry, and pretty much at the same time you’re going to water your plants.”

The best way to save water with this system? “Figure out how much grey water your home produces,” says Allen. “Then, determine how much water your plants need so you can properly irrigate them.”

Can You DIY a Grey Water System?

Yes. If you have basic plumbing and landscaping skills, you can install a simple “laundry-to-landscape” type system. This taps into water directly from the washing machine and without altering the plumbing of your home. The materials cost around $300.

Some water agencies offer incentives to offset the cost for this system. Other systems warrant more plumbing skills, and some require a professional installer.

Also, you’ll need to research state, county and city regulations, because the legality of grey water systems varies. It often depends on the type of system, where it’s installed (home or business) and the volume of water that passes through it.

Also, keep in mind you’re typically not allowed to store grey water for more than 24 hours. You should avoid products high in salt or containing Boron. Organizations like Greywater Action provide info on what soaps are safe for your plants and how to install a grey water system.

That’s often a penny-wise but dollar-foolish decision for two reasons. Homeowners end up paying more for repairs in the long run than a replacement would cost, and also waste money on inefficient heating and cooling.

Tim David, the CEO of Airlucent.com and an HVAC pro with more than 25 years of experience, says upgraded energy efficiency requirements from the Department of Energy are making new HVAC systems more expensive. “Consumers … should expect slightly higher costs for equipment, but better efficiency on their energy bills,” he says.

Still, HVAC system replacement is often more cost-effective than repairing an outdated system. It’s like spending thousands keeping your 20-year-old clunker on the road versus buying a modern, fuel-efficient vehicle.

According to HomeAdvisor, the national average cost for installing a new HVAC system is around $7,000, but that depends on several factors. Here are some tips to determine your costs for a new HVAC system.

Factors That Determine the Cost of HVAC System Replacement

The cost of HVAC replacement depends on where you live and the nature of the system (furnace vs. heat pump). It could range from $3,000 to $10,000. David says it costs about $3,000 to install a new electric furnace, and $5,000 to $8,000 to install a new heat pump.

“With the subsidies now in place for upgrading your home to be more energy efficient, you can claim up to $2,000 as a write-off,” says David. “And if you upgrade your insulation/windows, that could be another $1,200.”

It should be noted the $2,000 subsidy applies only to heat pumps. It’s part of the federal government’s move toward electric home heating methods.

If you already have a gas furnace and it makes sense to continue using gas, replacing your furnace will range from $3,800 to $10,000, or slightly higher if you opt for a high-efficiency model. If you heat your home with oil, furnace replacement will run between $6,750 and $10,000. These costs are determined by:

• The brand of equipment;
• The size of your home’
• Your climate zone;
• The local cost of labor.

Signs That It’s Time for a New HVAC System

David says it’s time for replacement when your system is at least 15 years old, and you have to call out an HVAC tech at least once a year for three consecutive years.

Both conditions indicate the system is functioning at a lower efficiency it should, wasting energy and money. David also notes if a single repair approaches 50% of the cost of a new system, you should just replace it.

“Most likely, something major is going on,” says David. “And if you don’t replace the whole thing, then you could be adding unnecessary stress to other older parts that don’t get replaced.”

DIY vs. Hiring Pros

It’s technically possible for a homeowner to DIY an HVAC installation, but David doesn’t recommend it. “HVAC systems are complex, require permits and specialized tools, and involve safety hazards,” he says. “Improper installation can result in poor performance, higher energy bills, and safety hazards for homeowners and their families.”

Another problem with DIY installation: It may void the product warranty. Most HVAC parts manufacturers require installation by licensed HVAC contractors for the warranty to be valid.

“Even if you have the necessary skills, although you will be able to save on labor costs, DIY installation can result in unforeseen additional costs due to mistakes, safety hazards, and the need to hire a professional to fix any issues that arise,” says David.

Questions To Ask HVAC Contractors

With government subsidies for HVAC upgrades now in effect, an HVAC contractor is the best person to advise you on how to take advantage of them. You can ask questions like:

• Is my home a good candidate for a heat pump?
• I want to continue using gas. Is it worth it to upgrade to a high-efficiency furnace?
• Will it make any difference to my comfort level and energy bill if I spend more money for a system with a higher efficiency rating than the minimum required?
• Will this HVAC replacement involve any changes to other components of the system, including the air handler and ductwork?

Of course, before hiring any contractor, always verify licensing and how long they’ve been in business. To avoid overcharging or substandard service, it’s also a good idea to check references and reviews on social media.

Like many projects, careful planning is a must to ensure proper installation. Always remember, safety first.

Here’s some additional advice about outdoor hot tub wiring and questions to ask before you buy a hot tub.

Before You Start Your Indoor Hot Tub Wiring Project

Don’t proceed until you’ve considered the following:

Type of hot tub

There’s more than one kind of hot tub (aka spa), and the National Electrical Code (NEC) has different rules for different types. Here, we’re talking about self-contained hot tubs.

The hot tub should include a label indicating it’s approved for indoor use. Look for a manufactured unit that includes the tub vessel, water pumps, water heaters and control equipment, all entirely under the skirt.

Hot tub safety certification

Be sure the hot tub is certified and labeled by a nationally recognized testing laboratory like UL, ETL, CSA, MET or another accredited product evaluation and certification organization.

Location

For safety, receptacle outlets, lighting, switches and other electrical apparatus must be out of reach of people in the tub.

Self-contained hot tubs feature a removable panel for access to the main electrical control panel, water pumps and other equipment within the skirting. Make sure there’s at least 36 inches of permanent space in front of the access panel.

Electrical capacity

A hot tub uses a lot of power. This usually requires a dedicated feeder or branch circuit rated at 120/240 volts, and anywhere from 30 to 50 amperes.

Electrical connection

Self-contained tubs may be cord connected, convertible or permanently wired.

A convertible hot tub comes from the factory with a power-supply cord but may be field-converted for a permanent connection.

Permits and inspections

Whether you install the wiring yourself or hire a licensed electrical contractor, your local building inspection office will require permits and inspections. An electrical inspection is the most affordable insurance you can buy!

Gather Tools and Materials

Save time and frustration by gathering these items before starting a hot tub wiring project.

Tools

• Hearing protection, safety glasses, work gloves and sturdy footwear.
• Electrician’s diagonal and side cutting pliers and tongue-and-groove pipe pliers.
• Digital multimeter and noncontact voltage sniffer.

Materials

The nameplate on your hot tub will display the voltage and amperage requirements. These dictate the size of circuit breakers, cables and wires, conduits and other electrical materials.

Your existing main service panel will dictate the type and style of the feeder circuit breaker that supplies the hot tub maintenance disconnect switch. Other conditions at your home will also impact the installation. Before you start, gather these materials:

• Hot tub maintenance disconnect switch with factory-installed GFCI protection.
• Four-wire Type SER aluminum service-entrance cable (two hots, one neutral, one equipment grounding wire).
• Two-pole, 240-volt feeder breaker for the main service panel.
• One-inch Schedule 40 PVC conduit and fittings, or one-inch liquid-tight flexible nonmetallic conduit and fittings.
• #6 AWG copper insulated wire (black, red, white and green).

Indoor Hot Tub Wiring Checklist

Make a checklist to guide you through the process:

1. Gather all of the necessary materials and tools.
2. Turn off the MAIN breaker at your service panel.
3. Put on safety glasses, work gloves and sturdy footwear and carefully remove the cover from your service panel.
4. DANGER! The incoming wires from the electric utility meter will still be energized (hot).
5. Install the hot tub feeder circuit breaker in any suitable vacant space in the service panel.
6. From the hot tub feeder circuit breaker, install the Type SER cable from the service panel to the maintenance switch at the hot tub location.
7. The maintenance switch must be readily accessible, within sight of the tub, and at least five feet from the inside walls of the tub.
8. Follow the manufacturer’s instructions for installing wiring from the maintenance disconnect switch to the hot tub control panel. Options may include a cord-and-plug connection, Schedule 40 PVC conduit or liquid-tight flexible nonmetallic conduit.
9. Once all of the wiring connections have been terminated and the wiring is safe to be energized, turn on the feeder circuit breaker at the service panel and the GFCI circuit breaker at the hot tub disconnect switch.
10. Use your voltage tester to check for proper voltages. If everything is good, test the hot tub.

Indoor Hot Tub Wiring Reminders

Keep these things in mind before wiring your indoor hot tub:

• You must follow the National Electrical Code (NEC) and the hot tub manufacturer’s installation instructions.
• Self-contained indoor hot tubs generally require a four-wire branch circuit with two hot conductors, a neutral conductor and an equipment grounding conductor.
• Hot tubs require ground-fault circuit-interrupter protection (GFCI).
• Check the manufacturer’s installation instructions to see if copper wire is required for the final connection to the hot tub control panel.
• At least one general-purpose 15- or 20-ampere GFCI-protected receptacle must be provided for tub maintenance. It must be not less than six feet and not more than 10 feet from the inside wall of the tub.
• All other receptacles in the area must be at least six feet, measured horizontally, from the inside walls of the tub.
• All receptacles rated 120 volts through 240 volts, 60 amperes or less, and within 10 feet of the inside walls of the tub must be GFCI protected.
• Light fixtures, lighting outlets and ceiling-suspended paddle fans located over the hot tub or within five feet from the inside walls of the hot tub must meet specific clearances from the maximum water level as follows:
  • Light fixtures are permitted to be installed less than seven feet, six inches if they meet either one of the two following conditions: 1. The lighting is GFCI protected, approved for use in a damp location, and it’s recessed in the ceiling with a glass or plastic lens, or 2. The lighting is GFCI protected, approved for use in a damp location, it’s surface-mounted with a glass or plastic globe, and it has a nonmetallic body.
  • Light switches must be located at least five feet, measured horizontally, from the inside walls of the hot tub.

Many people find their hair is drier when showering with unfiltered or hard water, and dry hair can be more prone to fizziness and dandruff. A water filter can also be used to treat dry skin. If you have eczema or psoriasis, you might find that a shower filter is just what you need to help relieve dryness.

With more than 11,000 five-star ratings on Amazon, the AquaHome in-line shower head filter is designed to remove harsh chemicals and heavy metals from your tap water. Plus, the filter can be installed in seconds on almost any showerhead without tools.

We tested the popular AquaHome shower head filter to see if it lives up to the hype—scroll on to find out how we tested the AquaHome filter and what we discovered after thoroughly using the product.

What Is the AquaHome Shower Head Filter?

The AquaHome shower head filter helps remove chloramine, fluoride, chlorine, heavy metals, sediment and pesticides from tap water. It comes in a 15- and 20-stage filter design, which cleans your water and reduces dry skin, hair and nails.

Additionally, the AquaHome connects to virtually any showerhead type, including fixed, rain, handheld and smart showerheads. The installation process is quick and doesn’t require any tools (unless your showerhead is screwed on so tightly that a wrench is needed to unscrew it). Before installing the shower filter, you’ll want to wrap Teflon tape around the thread of the shower arm and shower filter. The filter fits between the shower arm and the shower head.

Why is the AquaHome Shower Head Filter Trending?

The AquaHome is super popular among TikTokers like @haulswithhales because it’s said to help with hair loss, rosacea and keratosis pilaris (those little bumps on the skin sometimes called “chicken skin”). More than anything, users note noticeable improvements in their hair health.

In addition to adding shine to your hair, a water filter like the AquaHome can relieve itchiness, dandruff and eczema. It can also prevent the growth of fungi, bacteria and mold in your shower area, which can harm your health. Because the AquaHome is affordable and easy to install, people are snatching it up left and right to try it out for themselves.

How We Tested It

We tested the AquaHome shower head filter to see if the claims about improved hair and skin texture are valid.

The installation process was as easy as removing the handheld showerhead, twisting the filter onto the shower arm and reattaching the showerhead. You’ll want to use Teflon tape and tightly attach the filter and showerhead to prevent leaks.

I showered with the AquaHome for about two weeks and noticed a few key differences in my shower experience. Firstly, my shower water smelled and tasted better. (I wasn’t filling up glasses of water from my showerhead, but water inevitably gets into my eyes and mouth during a shower.)

And just like filtered tap water from the kitchen sink, the filtered water from my shower was tangibly cleaner. Beyond a difference in my water’s taste and smell, I also noticed less soap scum buildup on my shower floor and walls (a sign of hard water from calcium reacting with soap to form a residue).

Now, for the part you’ve probably been scrolling for, did I notice improvements in my hair and skin? Yes and no. My hair seemed softer and bouncier after using the AquaHome filter, but the jury’s still out on skin improvements.

For reference, I have straight, coarse hair prone to frizz, which often looks weighed down. Showering with a filter reduced frizz and made my hair feel lighter. I don’t color my hair, so I can’t speak to how it affects color-treated hair, but multiple users noted that the filter helps their hair color stay bright longer.

I also have extremely sensitive skin and keratosis pilaris. Eczema and psoriasis are other skin issues I deal with on and off. While I rarely emerge from a hot shower without looking like a tomato, the AquaHome reduced some of the redness and itchiness I experience post-shower. It also seemed to soften spots on my skin where I don’t always apply lotion, like the back of my shoulders.

I tested the AquaHome shower head filter during extreme winter weather, so I was more proactive about applying lotion after each shower. However, my skin didn’t seem to dry out as much in between showers when using the filter.

The most significant difference I noticed while using the shower filter was in my hair. Perhaps with long-term use, I would see more differences in skin texture and softness. Still, I didn’t notice anything incredibly noteworthy about how the filtered water affected my skin.

FAQ

Do shower filters actually work?

In short, yes, shower filters do work. One of the main reasons for using a shower filter is to remove chlorine, which can negatively affect skin, hair, throats and lungs. While some experts say that shower filters don’t treat all of the water quality issues they claim to, most do well at managing chlorine-related issues, which can specifically affect the hair and skin.

What type of shower filter is the best?

The best shower filter will remove as many impurities as possible that can lead to dry skin and hair concerns. Shower filters that are easy to install, cost-efficient and don’t cause any leaks are ideal. Some filters will infuse vitamins for better hair care—the AquaHome infuses water with vitamin C.

The most effective shower filters use a KDF (Kinetic Degradation Fluxion) process to filter the chlorine and other impurities out of water. The AquaHome uses a KFD-55 system, the most common among KFD filters.

Is a shower filter good for hair?

Shower filters are vital in removing excess chlorine from your water, which affects hair. Your hair (and skin) will be dry and damaged if too much chlorine absorbs into the follicles.

How long do shower filters last?

Shower filters typically last for six months, depending on your chosen filter. The AquaHome filter should last the prescribed time of six months. Although some filters can last longer, we recommend regular replacement to ensure effectiveness (like you’d see for a fridge filter).

What Other Shoppers Had to Say

This time, instead of fungi-inspired lamps, you’ll soon be seeing doughnut lamps—and yes, they are shaped like the sweet pastries. Doughnut lamps, also known as donut lamps, bring an unexpected look to rooms and can fit many decor aesthetics from mid-century modern to industrial and anywhere in-between.

What Is a Doughnut Lamp?

Doughnut lamps are sculptural lamps shaped like a circle with a hole in the center. In structure, they resemble the breakfast item, which is why they’ve received the nickname “doughnut lamp.” The lamp style combines a modern sensibility with a retro vibe and shape, so they fit perfectly in a mid-century modern room, gallery or eclectic space that combines several influences to create a cohesive design.

Depending on the iteration, doughnut lamps may feature a modern or earthy color and texture such as with a white ceramic or stoneware base, or a modern vintage look with orange glass. When lit, doughnut lamps might cast a dreamy, cozy glow, as with the case of the glass version from IKEA, or a nice, bright table-side light.

These stand-out pieces should fit just about any modern aesthetic, but if you aren’t sold on doughnut-shaped lighting, take a look at these modern table lamps for a wider range of options.

Where Can I Get a Doughnut Lamp?

The doughnut lamp leading the trend is none other than IKEA’s VARMBLIXT LED Table and Wall Lamp ($50). The VARMBLIXT lamp features a round body with an orange glass shade shaped like a doughnut. Designed by Sabine Marcelis in partnership with IKEA, the VARMBLIXT features a mounting system that makes it possible to put it on the wall, but you can also use it as a table lamp. The interesting design is also quite utilitarian—it comes with an energy-saving LED light source, so there’s no need to change the lightbulb. If you want to get your hands on the IKEA doughnut lamp, the entire VARMBLIXT collection will roll out in stores nationwide starting February 2023. You’ll also be able to order the doughnut lamp online through IKEA’s website.

Other doughnut lamps are available from online stores like Amazon and Wayfair, or small stores through Etsy, though their designs vary. For instance, this sculptural doughnut wicker pendant lamp ($195) will bring a retro vibe to your space. However, lamps built like the one from the VARMBLIXT are few and far between—IKEA may have started a new trend!

For those who like the mushroom and doughnut trend and can’t decide on just one, there’s a funky orange lamp from Lumens ($320) that looks like a mushroom sprouting a doughnut top—the perfect unexpected combo. You can also get a similar white mushroom-doughnut lamp from Etsy for $168.

Cove Lighting

Effective lighting is especially important in places such as the kitchen where precision is your top priority. Give cove lighting a try if you’re seeking a unique, ambient light in that room.

Unfortunately, CDC-approved portable high-efficacy particulate air (HEPA) cleaners can be expensive at $300 to $600 each. While you can certainly buy cheaper options, they may not be as effective.

The Corsi-Rosenthal Box

With these limitations in mind, Richard Corsi, dean of Engineering at UC Davis, and Jim Rosenthal, chief executive of Tex-Air filters, teamed up to create an affordable DIY option in August 2020. The resulting Corsi-Rosenthal Box is easy to assemble, cost-effective and uses items you likely already have around your home.

In terms of efficacy, scientists at the National Institute for Safety and Health performed a study proving that the Corsi-Rosenthal Box “reduced aerosol exposure up to 73%, depending on the design, filter thickness, and fan airflow.” A second trial from Brown University and the Massachusetts-based nonprofit the Silent Spring Institute showed that the boxes reduced the synthetic chemical PFAS by 40 to 60% and phthalates by 30 to 60% in the rooms in which they were installed.

How This DIY Air Cleaner Works

The fan in the bow pulls contaminated air through the filters, where contaminated particles are trapped. Clean air then flows into the middle of the box, and is pushed out again by the fan. The box thus helps reduce the spread of pathogens, as well as dust, pollen, wildfire debris and cleaning chemicals.

If you place the box in a 10 x 10 x 10-foot room, with the fan on low, you can expect it to filter about one-third of the room’s air every minute. This is referred to as its “clean air delivery rate,”  300 to 400 cubic feet per minute for the Corsi-Rosenthal Box.

If you’d like to try the Corsi-Rosenthal Box for yourself, here’s everything you need to know to build one yourself.

Materials

To make the air cleaner, you will need:

• 4 (20 x 20 x 2-inch) household air filters
• 1 (20-inch) box fan
• Cardboard (such as the box the fan came in)
• Scissors
• Duct tape

The most important part of sourcing your materials is ensuring the quality of your air filters. Look for filters that have a MERV-13 rating, which confirms the filter’s ability to trap particles of a specific size.

According to Washington Post reporter Lena Sun, who recently tried building the box, these materials should set you back about $130. This does not take into account any materials you may already have on hand.

Directions

Corsi himself walks through the process here.

1. Gather your materials.
2. Position the shell. Position the filters so that the pleats are vertical, are the airflow arrows on the filters all point inside the box. For maximum durability and a perfectly square cube, abut the filters so that one skinny edge connects with the longer side of the other filter, continuing this pattern all around.
3. Secure the shell with duct tape. Seal the full length of every connecting edge with duct tape so there are no gaps. Doubling up the tape is even better.
4. Build the floor of the box. Cut your cardboard to fit the bottom of the box, then attach it to the filters with duct tape, sealing every edge completely.
5. Position the box fan on the sixth side of the cube so that it will blow air out of the box into the surrounding room. Attach the box fan to the filters, ensuring that all gaps are completely taped up. If needed, you can use small pieces of cardboard in the corners to make sure no air escapes.
6. Lastly, because a box fan’s blades do not reach fully to the corners of the fan, you need to cover those corners up with cardboard. The simplest way is to cut out triangles and tape them to the top of the fan, but if you’re feeling ambitious, you can cut a circle in the blades’ diameter out of a square and attach that.
7. And that’s it! Plug the fan into an electrical outlet and turn it on!

Other Projects

Now that you’ve upped your COVID safety in the house, why not make another batch of masks? You don’t even need a sewing machine. Or, if this project inspired you to clean the air in your garage, try building a dust filter fan using any leftover filters. Stay safe and healthy out there!

• If possible, dig a trench five to six inches wide and as deep as the soil will allow from your water source to the area under your house where you plan to route the supply line. (Some areas have enough soil to bury the line, but not enough to protect it from freezing.) Where you route water into your home depends on your floor plan and the location of your water pressure tank. I brought in my supply line into my laundry room because that’s where my pressure tank is, and where my interior water pipes branch from.
• Lay lengths of 4-in.-dia. ABS pipe end to end in the bottom of the trench, or on the ground/bedrock if you can’t dig.
• Join the ABS ends together with ABS cement. If it’s a drilled well, extend the pipe to the well casing. If it’s a cistern, go to the main outlet. And if it’s a lake, right to the water.
• Thread a one-inch water supply pipe through the ABS pipe and connect it to your water source with a PEX expansion ring and ProPEX expander tool. Be sure to use PEX pipe because it won’t burst if the system ever fails and the water freezes.

It’s no wonder, then, that Christmas lights, with their twinkling and flashing and sheer ubiquity during the holiday season, can create problems for people with LED light sensitivity.

Why are some people affected by LED lights? Michael Meiser, lighting expert at Lumilum, says it’s because LED lights are brighter than incandescent or fluorescent lighting, and they emit blue light (more on that below). What’s more, with energy efficiency top of mind, we’re exposed to LED lights everywhere now.

Meiser says that time of year plays a part, too. “As people spend considerable time surrounded by bright, flashing Christmas lights, this will likely exacerbate symptoms of light sensitivity,” he says.

How Do LED Lights Work?

LED stands for light-emitting diode. “LED bulbs produce light by passing electric current through a semiconducting material [the diode],” Meiser says. When the the electrons in the diode are excited by the current, their movement releases energy called photons — aka light — through a phenomenon called electroluminescence.

In traditional incandescent lightbulbs, electricity heats up a tungsten filament — the spring-like metal piece inside the glass — which glows hot and emits light. One drawback? They emit a ton of heat, up to 90 percent of the energy consumed.

LEDs, by contrast, convert much more energy to useable light. Meiser says LED lights are 90 percent more efficient than regular incandescent, and 80 percent more than a halogen bulb. That means they’re cheaper to run and much more environmentally friendly than traditional lighting sources.

“Their energy efficiency is such that an LED bulb using five watts of power does the same job as a filament bulb using 40 watts,” Meiser says.

What’s the Problem with Purple LED Lights?

Purple LED lights aren’t really purple, but rather red and blue combined. Studies show blue lights interrupt our circadian rhythm, affecting sleep by suppressing melatonin production. Meiser says blue lights contribute to migraines and visual fatigue, too.

And while red light shows promise for medical use, particularly in dermatology, Meiser says “combining it with blue light triggers the photoreceptors in the eye linked to the part of the brain that controls alertness, causing people to strain their eyes.”

Then there’s the flicker. Our homes run on alternating current (AC). That means the electricity in your wiring constantly travels back and forth from the source (your electrical panel, and before that, the transformer and the utility) to the outlets in your home. This fluctuation causes all lights, not just LEDs, to continually dim or shut off with the frequency of the current.

LED lights employ drivers to provide a constant source of voltage and prevent flicker, but some people are more photosensitive than others. “The flickering from purple LED Christmas lights might trigger people with light sensitivity more than other colors,” Meiser says.

What Are the Symptoms?

If you’re sensitive to LED lights, you may experience headache, nausea, dizziness, eye pain and inflammation, along with burning, watery or dry eyes.

What Can You Do?

Meiser says you can reduce LED light sensitivity at Christmas, or any time of year, by taking the following steps:

• Avoid flashing Christmas lights. If your lights have two settings, keep them on static.
• Put lights on a timer so they won’t shine in your eyes all day.
• Switch lights off at least an hour before bed.
• Invest in blue light glasses, which block blue light before it reaches your eyes.
• Boost ambient light indoors to create a more balanced environment.

Luckily, there are a few things you can do to get your home warm and toasty again! We’ve rounded up six common conditions that cause furnaces to blow cold air, along with DIY fixes.

Incorrect Fan Settings

When troubleshooting, always start with the easiest possible solution. In this case, it’s the thermostat fan setting.

Check to see if the fan is set to ‘On.’ If it is, then it will blow air continually, whether or not the furnace produces heat. If your furnace always blows air, sometimes hot and sometimes cold, then it’s likely a fan setting issue.

This is more common on older thermostats with a physical fan control switch. These old-school switches can easily be bumped by an oblivious adult or a playing child. (I’ve seen this happen when moving furniture past a hallway thermostat.)

In this case, the fix is easy: Move the setting from ‘On’ to ‘Auto’ and see if that resolves the problem.

Dirty Filter

If your furnace or heat pump completes a full cycle but the air never quite warms up, it’s likely due to a clogged furnace filter.

This issue may seem counterintuitive. Most homeowners assume a blocked filter would prevent air from coming through the vents at all. But a furnace with a clogged filter still runs, and the blower still pushes air through the vents.

Of course, all that moving air comes from somewhere. The blower draws air through the path of least resistance. Normally, that’s through the filter and across the heating element. But if a dirty filter blocks it, the air will move through any crack or hole in the furnace body or vent system.

If your furnace is blowing cold air, check the filter to see if it should be replaced. After that, be sure to change your filter regularly and always use the properly-sized replacement. Clogged filters can cause any central heating system to blow cold air.

Pilot Light or Igniter Issues

Gas furnaces use a pilot light or igniter to spark natural gas into flame. If the pilot light goes out or the igniter fails, the heat will never kick on. Instead, the furnace will circulate cold air until the system recognizes the problem and shuts down. You’ll notice a strong, stable flow of cold air, then an abrupt stop.

Most newer furnaces don’t use a pilot light; they feature a solid-surface igniter that raises its temperature high enough to engage the natural gas. If your furnace has a bad igniter, it will need to be replaced. An extinguished pilot light can be relit; simply follow the directions on the furnace. If the pilot light keeps going out, it may need cleaning.

Dirty Flame Sensor

If your gas furnace begins to blow cold air, then cuts off abruptly, it could also be the flame sensor, which sits in the path of the flame. If the furnace cycles up but the sensor fails to detect the flame’s heat, it shuts down the furnace to prevent gas from invading your home.

It’s an essential safety feature, but the flame sensor can collect debris on its surface. If that happens, it will give a false alarm, ending the cycle before the circulating air can move from cold to warm.

Luckily, there’s a quick and easy fix. Turn off the power to the furnace, remove the flame sensor and clean it off with an emery cloth or fine steel wool. Use a light touch to avoid damaging the sensor, scraping along, not across, the surface. And never use a coarse grit sandpaper.

Once you get your furnace up and running again, order a replacement sensor. For most furnaces, they run around $10.

Flames sensors are found on gas furnaces, as well as heat pumps with a gas furnace as backup.

Clogged Condensate Line

All high-efficiency gas furnaces have a condensate line, as will any furnace connected to a central AC system. In all cases, this line allows excess water produced by the AC and furnace to drain away from the unit.

If dirt or debris block the line, water will back up. That will trigger a shut-off safety switch, or interfere with or damage the furnace. In either case, the furnace may not light. It will blow cold air, then shut down.

Fuel Issues

It’s possible a gas furnace won’t heat because it’s not getting a proper gas supply. This is another scenario where the furnace will blow cold air and then shut down.

Double-check the shut-off valves to make sure they’re open. If there’s still no gas reaching the furnace, it indicates an issue somewhere in that system. While it’s possible to troubleshoot gas lines, this kind of repair is best left to the pros. The risks are high and too many things could go wrong.

An electric furnace will blow cold or lukewarm air if one or more of the heating elements malfunctions. Replacing a heating element is complicated enough to warrant bringing in a pro.
