Formaldehyde is a colorless, pungent-smelling gas that is commonly found in many household products and building materials. It is a known human carcinogen, which means that it has been proven to cause cancer in humans. Formaldehyde is released into the air through a process called off-gassing, where it is emitted from products such as furniture, flooring, and adhesives. It can also be released from combustion sources like fireplaces and woodstoves.

Health Risks Associated with Formaldehyde Exposure
The concern about formaldehyde is that it can cause a range of health problems, from mild irritation to severe health effects. Exposure to formaldehyde can cause eye, nose, and throat irritation, as well as respiratory problems like asthma and bronchitis. Prolonged exposure to high levels of formaldehyde has been linked to an increased risk of cancer, particularly nasopharyngeal cancer and leukemia.
How Does Formaldehyde Affect Indoor Air Quality?
Formaldehyde is a major contributor to poor indoor air quality. It is a volatile organic compound (VOC) that can accumulate in indoor spaces, particularly in areas with poor ventilation. When formaldehyde is released into the air, it can react with other pollutants to form ground-level ozone and other hazardous compounds.
The presence of formaldehyde in indoor air can exacerbate respiratory problems like asthma and chronic obstructive pulmonary disease (COPD). It can also trigger allergic reactions and other health issues. In addition, formaldehyde can react with other indoor air pollutants to form secondary pollutants, which can further degrade indoor air quality.
Common Sources of Formaldehyde in the Home
Formaldehyde is a ubiquitous chemical that can be found in many household products and building materials. Some common sources of formaldehyde in the home include:
- Pressed wood products, such as plywood and medium-density fiberboard (MDF)
- Furniture, particularly those made from composite wood products
- Adhesives and glues
- Paints, coatings, and varnishes
- Cleaning products and disinfectants
- Air fresheners and deodorizers
- Carpets and upholstery
- Cigarette smoke and other combustion sources
How Air Purifiers Can Help Remove Formaldehyde
Air purifiers can be an effective way to remove formaldehyde from indoor air. Look for an air purifier that has a HEPA filter, which can capture 99.97% of particles as small as 0.3 microns, including formaldehyde. Some air purifiers also have additional features like activated carbon filters, which can absorb and neutralize formaldehyde and other VOCs.
When choosing an air purifier to remove formaldehyde, look for the following features:
- A HEPA filter or other high-efficiency filter
- An activated carbon filter or other VOC-absorbing material
- A high CADR (clean air delivery rate) to ensure effective removal of formaldehyde
- A sensor that can detect formaldehyde levels and adjust the air purifier's settings accordingly
Other Ways to Reduce Formaldehyde Exposure
In addition to using an air purifier, there are several other ways to reduce formaldehyde exposure in the home:
- Use formaldehyde-free products whenever possible
- Increase ventilation by opening windows and doors, or using fans to circulate air
- Avoid using strong chemicals or cleaning products that contain formaldehyde
- Remove sources of formaldehyde, such as pressed wood products or adhesives
- Consider using a dehumidifier to reduce the growth of mold and mildew, which can release formaldehyde
Health Risks Associated with Formaldehyde Exposure
Formaldehyde exposure has been linked to a range of health risks, including:
- Eye, nose, and throat irritation
- Respiratory problems like asthma and bronchitis
- Cancer, particularly nasopharyngeal cancer and leukemia
- Neurological problems, such as headaches and dizziness
- Allergic reactions and skin irritation
- Reproductive problems, including reduced fertility and birth defects
Measuring Formaldehyde Levels in the Home
There are several ways to measure formaldehyde levels in the home, including:
- Using a formaldehyde detector or sensor
- Conducting air sampling tests with a professional laboratory
- Using a DIY formaldehyde testing kit
- Checking the product labels and safety data sheets (SDS) of household products and building materials
Formaldehyde is a serious indoor air pollutant that can have significant health risks. By understanding the sources of formaldehyde, using air purifiers and other methods to reduce exposure, and measuring formaldehyde levels in the home, you can take steps to protect your health and improve indoor air quality.
Remember to always choose products and materials that are formaldehyde-free or low-VOC, and to prioritize ventilation and air circulation in your home. By taking these steps, you can create a healthier, safer living space for yourself and your loved ones.
