The Environmental Protection Agency (EPA) recognizes formaldehyde as a carcinogen, a cancer-causing substance, yet manufacturers still use it in glues, finishes, and adhesives for building materials and furniture. Over the course of days, weeks, and even years, formaldehyde off-gasses into the home, exposing homeowners and their families to dangerous fumes and poisons.

Urea formaldehyde is the most commonly used form of formaldehyde and is used as adhesive in plywood, particleboard, and as an ingredient in the lacquer on bookshelves and flooring. The newer the materials, the more they will off-gas into the home. This means that smaller, newer homes are more likely to have higher levels of formaldehyde gas. Although it is colorless, formaldehyde does have an odor that can cause symptoms in many individuals.

Because it is used in so many building materials, formaldehyde will off-gas from a variety of sources. These include but are not limited to:

• Furniture (plywood and particleboard make up the base of most goods)

• flooring

• cabinets

• bookshelves

• carpets (glue and adhesives used in placing and making carpets)

• upholstery (both formaldehyde and benzene are used as sealants but formaldehyde can be used in making many tougher fabrics, even drapes)

Homeowners are urged to allow new furniture and materials to off-gas in a well ventilated area prior to moving them indoors. This includes any building materials or new furniture. If you can, place these items under cover in an open garage or protected area in the yard. Although individuals with existing respiratory problems such as emphysema and asthma are especially at risk for experiencing symptoms, healthy individuals have been known to suffer from migraines, breathing difficulties, nausea, headaches, and sinus problems. Elevated levels of formaldehyde can eventually cause liver and lung damage.

Keeping your home well ventilated helps in maintaining good air quality inside. The EPA states that indoor air quality is usually far worse than outside and homeowners are urged to open doors and windows whenever possible to facilitate air exchange. Indoor air purifiers also help, but be sure to use ones with HEPA filters.

Alternatives to conventional materials are available. Natural alternatives to furniture, flooring, and accessories can help decrease toxicity levels in your home. Many of these products also support sustainable resources and environmentally friendly farming and manufacturing techniques. Visit for more information and access to natural resources.

There is currently no federal limit in the US for formaldehyde levels in the home.
