Formaldehyde

Formaldehyde is a chemical found in many household products and building materials, and is also produced by combustion. While formaldehyde is common in homes, it can be harmful to your health. The CDC says the cancer risk is low from typical indoor formaldehyde levels. Experts recommend keeping formaldehyde levels as low as reasonably possible in your home.

Health Concerns

  • Irritation of the skin, eyes, nose, and throat.
  • High levels of exposure to formaldehyde may cause some types of cancers.
  • Wheezing and coughing, fatigue, skin rash, severe allergic reactions.
  • Some develop a sensitivity to formaldehyde.
  • High concentrations may trigger attacks on people with asthma.

Potential Causes

Building materials and furnishings: furniture, flooring, pressed wood products, paints, sealants, glues, adhesives, and insulation.

Household products: cosmetics, scented products, air fresheners, toys, use of unvented fuel burning appliances, smoking, some synthetic fabrics.

Recommended Actions

  • Choose low-formaldehyde products when building or remodeling.
  • Keep heat and relative humidity levels low indoors.
  • Increase ventilation: heat or energy recovery ventilator (HRV/ERV), fresh air supply vent or ventilating dehumidifier.
