Formaldehyde is a common chemical found in environments like air conditioners, paper products, cigarette smoke, and nail salons. It’s a colorless gas that irritates the eyes, nose, and throat; the odor of formaldehyde is a chemical combination of formic acid and acetic acid .

Formaldehyde is toxic to humans and animals, and exposure can cause symptoms such as dry and irritated eyes, sore throat, and irritated skin. In your home, formaldehyde is derived from the following sources:

It is also stated that formaldehyde is also generated through combustion. When you burn natural gas, gasoline, and kerosene, formaldehyde is produced. Hence, if you have appliances inside your home that use these gasses, it is likely that you are exposed to formaldehyde .

Another thing that you need to know is that this substance is a residue of tobacco. Hence, households with tobacco smokers also deal with this problem, whether they are aware of it or not. In fact, it is highly likely that your home has traces of formaldehyde, but you are not aware of it yet. The invisible presence of these chemicals would call for the service of air purifiers from reputable manufacturers .

Is Formaldehyde Normal in Homes?

As mentioned, formaldehyde is found in many common household items, including carpets, permanent-press clothing, foam in mattresses, and wall paints. But does this mean that formaldehyde is a normal occurrence in homes?

Based on the information published by the US Consumer Product Safety Commission, formaldehyde is typically present in both outdoor and indoor air. The good news is that they are only at low levels, specifically lower than 0.03 parts per million.

However, it is clearly indicated that formaldehyde is not naturally occurring. This means that they are not present in the “normal” air composition. It is a chemical that is produced by different sources, such as the combustion of vehicles. Hence, the presence of formaldehyde in your home should not be treated lightly. As much as possible, you need to address this matter right away.

What are the Side Effects of Formaldehyde Exposure?

Again, we have to emphasize that formaldehyde exposure isn’t something that you should treat lightly. Formaldehyde is toxic, so it’s both harmful to humans and animals. Prolonged exposure to this chemical at high levels may mean that you are prone to various harms, such as the following:

But these are just minor side effects. Exposure to large quantities of formaldehyde can cause specific types of cancer in humans . Even in laboratory test animals, the same result has been found. Examples of these cancer types are the cancer of the nasopharynx and cancer of the nasal sinuses.

Furthermore, individuals who are working in conditions where there’s a lot of formaldehyde, such as embalmers and hospital professionals, are prone to developing leukemia.

These are among the reasons why you should avoid formaldehyde exposure at all costs.

Formaldehyde isn’t a natural aspect of your home. Hence, you should be aware of the common sources of this chemical. In this way, you will be able to avoid having severe formaldehyde emissions within your house or building.

Here are the top sources of formaldehyde in homes:

Walls and Floors

The flooring and walls of your space could be a rich source of formaldehyde, especially if there are adhesives applied to them. Many paints have formaldehyde on them, so you better watch out for the type of paint that you are going to use. You may want to opt for those that have low or zero volatile organic compounds (VOCs).

If there are wood panels on the walls of your building or house, there’s a good chance that formaldehyde is present.

Bedroom Furniture

Many types of bedroom furniture are crafted through the use of pressed-wood materials, such as particle board, plywood, and fiberboard. While they appear harmless, these materials have been processed with the use of formaldehyde.

If the furniture says that it is fire retardant, there’s also a possibility that it contains formaldehyde. This is an issue since, at room temperatures, formaldehyde turns into a gas and becomes an emission.

Personal and Home Products

Many household products and personal amenities contain formaldehyde. For instance, your balm, hairspray, and makeup are processed in settings where formaldehyde is present. In fact, there’s a possibility that formaldehyde is part of their compositions.

While they sit idle on your shelves or cabinets, these products could release formaldehyde and other VOC in the air. So make sure that they are sealed properly and free from high-temperature exposure.

Gas Stoves

Interestingly, natural gas is among the few exceptions where manufacturers don’t have the responsibility for formaldehyde emissions. When using gas stoves, the natural gas would automatically release formaldehyde, carbon monoxide, and nitrogen dioxide into the air.

Because of this, it is crucial that an exhaust hood should be present in your kitchen if ever you are using gas stoves. In this way, these residues would be expelled from your kitchen, preventing you from inhaling them.

Why Is Formaldehyde Purification Important?

We have already mentioned the potential dangers of formaldehyde in your health. Because of this, you need to learn different methods on how to curb its presence. As much as possible, you would want your home to be free from this chemical.

In the following sections, we will introduce several tested-and-proven methods that are effective in removing formaldehyde and different types of VOCs in your living spaces.
Adding Air Purifier to Get Off Formaldehyde
If you want a foolproof method of removing formaldehyde in the air , then you have to invest in an air purifier. Many of you have already heard about these air purifiers. Essentially, these are devices that capture different airborne pollutants.

But at the same time, many are unaware that it is not only pollen, allergens, and pathogens that these devices can deal with. Air purifiers are also known to be effective against lingering substances, chemicals, and odor-causing pollutants.

Specific AHAM-certified air purifiers can handle formaldehyde properly. Those that have the appropriate filters would be able to reduce the presence of formaldehyde in any given space. In a short while, you’ll know how air purifiers can do this feat.

Why Is an Air Purifier Important to Improve Air Quality?

Your indoor air quality is often compromised by different pollutants. From the dust outside your home down to the hair of your pet, these things can gradually reduce the overall breathability of your indoor air.

Of course, there are numerous ways you can improve polluted indoor air. We can list multiple ways for that. However, if you want a foolproof, no-nonsense approach, then you should opt to use an air purifier.

After all, these devices are designed to do one job, and that is to eliminate airborne particles that could potentially cause various health issues. With air purifiers, you can guarantee that your home will have fresh, breathable air.

Air Purifier for Formaldehyde

Air purifiers remove any small particles of dust or dirt from the air, reducing the chances of respiratory allergies and asthma. The purifiers remove the particles mechanically by forcing air flow through their filters.

One of its filters, called the activated carbon filter or charcoal filter, is the one responsible for removing various VOCs and chemicals in the air. When the air passes through the carbon filter, those substances are being “broken,” ensuring that they won’ t be released back into the air.

Hence, if your air purifier has carbon filters, your indoor space would be free from possibly harmful chemicals. It is an important filter that should be present in an air purifier should your problem be related to these toxins and gaseous substances.

Is Air Purifier for Formaldehyde Safe?

Yes. Air purifiers that use filters are generally safe. These devices don’t emit harmful emissions that could trigger allergies and respiratory illnesses. These filters don’t have chemicals on them either. They can capture contaminants through the standard process of filtration, which has been used for many centuries already.

When these air purifiers remove formaldehyde, no residual matters are being released into the air. That’s how “clean” and “seamless” these air purifiers are.

The only type of air purifier that you need to watch out for is an ozone generator. As its name suggests, an ozone generator is designed to reduce gaseous ozone in the air. These ozone gasses are said to neutralize contaminants in the air. However, keep in mind that its effectiveness is not that impeccable as compared to filter-based air purifiers. Moreover, ozone is a lung irritant that could harm your health.

How Do Air Purifiers Work to Remove Formaldehyde?

As mentioned earlier, air purifiers have activated carbon filters on them. Of course, there’s no magic on these carbon filters. They follow the tested-and-tried principle of adsorption.

Adsorption is a type of chemical reaction. Particles that are subjected to this process are then trapped in the porous structure of the filter. Over time, these substances would get broken, ensuring that there would be no remnants on them.

Because of the effectiveness of carbon filters, they are typically utilized by various industries in collecting airborne chemicals and gasses, as well as odor-causing substances. Of course, the same mechanism is also used in air purifiers.

Removing Formaldehyde by Air Purifiers: Step-By-Step

Here’s how air purifiers remove formaldehyde and VOCs. Overall, the process is simple but effective.

  1. The air purifier draws the air toward it through the use of its fans.
  2. Meanwhile, the air passes through several layers of filters. Once it reaches the carbon filter, the chemicals and substances are trapped in the porous layer of the filter. This is where adsorption takes place.
  3. After the carbon filter, the air is then released back into the room.

This process is repeated until such time the air in a given room is already free from various pollutants.

How Long Does It Take Formaldehyde to Settle After Removal?

It depends on the severity of the formaldehyde emission in your space. For instance, if the concentration of formaldehyde is to spread, then it is possible that it would take a while before an air purifier can remove the said chemical.

It would take quite some time before the traces of formaldehyde would be removed in large spaces, especially if the air purifier that you have is rated to be effective only in small spaces. And that would bring us to our next section.
