There are a wide variety of toxic chemicals lurking in your home, and while you can take steps to minimize them, one the most prevalent chemicals in your home isn't easy to get rid of. Formaldehyde, a volatile organic compound that's emitted in low levels by a variety of household building products and furniture, may cause cancer in humans and has been known to trigger asthma attacks and allergic reactions when present in high levels. A common component of glues that hold pressed-wood or particleboard furniture and cabinets together, it's also emitted by natural gas stoves, carpet glues, flooring glues, caulks, sealants, paints, furniture finishes, and the water- and stain-repellent finishes applied to upholstery and clothing.
Although government regulations have reduced the amount of formaldehyde used in insulation and particleboard furniture, the sheer number of potential formaldehyde emitters found in the average home makes the chemical difficult to avoid. The good news: you have a cheap, easy, green tool at your disposal to help get rid of it. Add these seven household plants that NASA scientists have discovered help remove formaldehyde and purify air to your home for a safer, cleaner atmosphere.
