Formaldehyde is a colorless, strong-smelling gas and a common volatile organic compound (VOC) found in many building materials, furnishings, and household products. It can off-gas into indoor air, contributing to irritation of the eyes, nose, and throat and worsening respiratory symptoms for sensitive occupants. Managing formaldehyde levels involves choosing low-emitting materials, improving ventilation, and controlling indoor humidity.

Why is formaldehyde a concern indoors?
It is a VOC that can irritate the respiratory system and contribute to poor indoor air quality when it off-gasses from materials.

Ventilation and low-VOC materials help reduce formaldehyde.
After installing new cabinets or flooring, homeowners can reduce formaldehyde exposure by increasing fresh-air ventilation and using air purifiers with activated carbon.
Ventilate well after adding new furniture or finishes, and consider carbon-based air filtration to reduce VOCs like formaldehyde.

Formaldehyde emissions have been regulated more tightly in many building products to improve indoor air quality.
How can I lower formaldehyde levels at home?
Increase ventilation, choose low-VOC materials, and use activated carbon filtration when possible.
Does humidity affect formaldehyde?
Yes. Higher humidity and temperature can increase off-gassing rates.
Are air purifiers effective for formaldehyde?
Units with activated carbon or specialized VOC filters can help reduce formaldehyde levels.
