Potential sources of formaldehyde in your home

Formaldehyde is often associated with industrial settings, but it can also exist in your home. The following are some of the potential sources of these harmful gas:

  • Fuel-burning appliances. The likes of kerosene space heaters and gas stoves can produce formaldehyde if not used properly. Also, lack of ventilation in the area of use will increase the risk of having high levels of formaldehyde in your home.
  • Cigarette smoke. Whether it’s tobacco or e-cigarette, smoking produces formaldehyde. This is the biggest reason why you should never smoke inside enclosed spaces. Better yet, don’t smoke at all.
  • Household products. Paints, coatings, glues, and even press fabrics can also off-gas formaldehyde. There are also some fabric softeners and dishwashing liquids that can emit this toxic gas.
  • Pressed wood products. If your home was recently remodeled or renovated, you should check if the materials used contain formaldehyde resins. The most common sources of formaldehyde in construction sites are particleboards, hardwood plywood paneling, and fiberboards.
  • Beauty products. Even the beauty products you use can also release formaldehyde. Nail polishes are notorious for this as well as nail hardeners, soaps, makeup, and hair products. Still, not all of these products will automatically have the dangerous formaldehyde. Always read the label and be smart with your options.

How air purifiers remove formaldehyde in the air

Are you worried about having formaldehyde in your home? Or is your home tested for formaldehyde? If so, air purifiers will be your first line of defense aside from proper ventilation.

However, you should know that not all air purifiers in the market can remove formaldehyde. You have to look for one with activated carbon or an activated charcoal filter. These porous materials will trap volatile organic compounds (VOCs) like formaldehyde so that they won’t recirculate in your indoor air.

Still, an air purifier is only a part of the solution. Depending on the level of formaldehyde in your home, you may need professional help to restore the cleanliness of your indoor air.

Also, you should remember that air purifiers also need maintenance. You have to replace the filters regularly to ensure that they will continue to remove formaldehyde in your home. Otherwise, you’re just defeating the purpose of having an air purifier.

How to choose an air purifier that removes formaldehyde

There are many air purifiers in the market, but not all of them are effective in removing formaldehyde in your room. To help you find the right pick, you should consider the following points:

✔️Filter type

The very first thing you should check is the filter type of the air purifier. This is the part that will dictate whether the unit can remove formaldehyde in your home or not.

To ensure that the air purifier can remove formaldehyde, look for one with an activated carbon filter. Activated carbon can trap volatile organic compounds like formaldehyde.

Take note that HEPA filters alone can’t remove formaldehyde in the air. While this efficient filter can remove airborne particulates, it does very little when it comes to harmful gasses.

One of the most popular technologies in the air purifier market is Photoelectrochemical oxidation (PECO). This technology is developed to destroy organic matter, including volatile compounds.

Nevertheless, high-density and premium activated carbon will still do a good job in filtering out formaldehyde in the air. Remember that activated carbon filters are often measured by weight in pounds. The heavier it is, the more powerful it will be in removing VOCs.

✔️Capacity and room rating

Next, you should consider the capacity of the air purifier you’re going to buy. It’s not enough that it can filter out formaldehyde; it should also be powerful enough for the floor area of your room.

This is often measured through CADR or Clean Air Delivery Rate. It refers to how fast an air purifier can remove pollutants in the air within a specific timeframe. It’s gauged by CFM or cubic feet per minute.

Most air purifiers are tested for dust, smoke, and pollen, while there are also units that underwent more rigorous testing.

Aside from the CADR of the air purifier, you should also check the floor area rating. It’s often provided alongside the CADR to help buyers find the right unit for their homes. By matching the air purifier to your room size, you’ll enjoy efficient air cleaning without consuming too much electricity. 

✔️Noise level

For those who have babies or very sensitive hearing, the noise level of the air purifier is often a make-or-break part.

To be fair, the noise level is always a trade-off if you want a powerful air purifier. Just remember that bigger air purifiers with powerful engines are normally louder than compact options.

If you’re bent on using a quiet air purifier, look for one with adjustable fan speeds. This will let you set the unit in quiet mode at night.

✔️VOC sensor

A VOC sensor will detect increased volatile compounds in the air, including formaldehyde. From there, the air purifier will adjust its speed to help regain the room’s clean air.

However, only a few air purifiers have this function. The price tag is also steep but worth the splurge if you want efficient indoor air cleaning.

✔️Controls and adjustments

Make sure that the air purifier of your choice will let you adjust the fan speed. This is crucial since it will affect the cleaning power and noise level of the unit.

If the air purifier has a built-in light, make sure that it can be turned on and off based on your liking. This will prevent disruptions at night.

Also, you can consider investing in a smart air purifier. These options are Wi-Fi enabled, which allows you to control the unit through your smartphone. It’s very convenient since you can check on your indoor air even if you’re not at home.

✔️Ozone-free operation

Old technologies used on air purifiers utilize ozone to destroy volatile compounds like formaldehyde. It’s efficient, but prolonged exposure to ozone can also lead to health complications.

With this, you should guarantee that the unit you’re purchasing isn’t producing harmful ozone that will do more harm than help.

✔️Certifications

All appliances undergo testing and certification process from multiple third-party laboratories. It ensures that the units are safe, effective, and at par with industry standards.

For air purifiers, try to look for the following certifications:

  • ENERGY STAR. This certification shows that the air purifier is energy-efficient. It means that the unit uses less electricity than non-certified options.
  • AHAM Verifide. This certification means that the air purifier has passed the organization’s standardized lab test. It certifies that the unit can eliminate dust, smoke, and pollen efficiently.
  • CARB. CARB stands for California Air Resources Board. A certification from CARB means that the air purifier is free of ozone and other hazardous emissions.

✔️Dimensions and size

The physical dimensions of the air purifier are also important, especially if you have a small home. Still, you shouldn’t compromise the unit’s efficacy when it comes to removing formaldehyde.

If you don’t have the luxury of space, look for an air purifier tower. This has a horizontal design and a small footprint that can fit in a corner. There are also wall-mounted air purifiers that will let you save space.

✔️Price and warranty

Lastly, check the warranty of the air purifier you’re going to buy. An air purifier that removes formaldehyde doesn’t come cheap, so it’s important to have protection on your purchase.


How to avoid formaldehyde in your home

As much as formaldehyde is dangerous, there are ways to reduce your exposure to it. Here are some of the things to keep in mind:

  • No smoking inside your house. It’s important to impose a strict rule that no smoking of any kind is allowed indoors. Aside from formaldehyde, cigarette smoke contains other harmful compounds that could trigger asthma attacks and respiratory diseases.
  • Operate generators at a distance. If you’re using a portable generator, make sure that it’s at least 20 feet away from your house. This will allow carbon monoxide and formaldehyde to dissipate properly.
  • Opt for sealed pressed wood products. If you’re buying furniture made of pressed wood, make sure that it’s properly sealed to prevent off-gassing. But to be sure, it’s best to invest your money in solid wood pieces. It’s more aesthetic and durable than pressed wood versions.
  • Observe proper ventilation. Make sure that air is moving inside your home to allow formaldehyde to dissipate right away. Always keep your vents working and consider installing ceiling fans to funnel air in and out.
  • Aerate new furniture. If the furniture you bought has a strong smell, you should aerate it for several days before bringing it indoors. This will allow formaldehyde to dissipate naturally instead of getting trapped inside your house.
  • Clean your fireplaces. Burning fuel inside your house increases the formaldehyde levels in the air. It’s important to clean your fireplaces and furnaces regularly to prevent the risk of poisoning.
