A NASA-approved study proved that certain plants can remove the build-up of some major household pollutants.

Some house plants do double duty, both decorating a room and helping purify the air in the space, and that's what makes them the perfect addition to your home. In the summer of 1989, NASA and the National Association of Landscape Professionals conducted a study using houseplants as a natural way to produce and clean the air in space stations. According to their findings, plants that required low light demonstrated a surprising potential for improving indoor air quality because they helped remove the build-up of pollutants like benzene, formaldehyde, and richloroethylene (some of which are found in household supplies and furniture). It stands to reason, then, that we might consider living like those space-bound astronauts and populating our living spaces with more living plants.

Their leaves absorb carbon dioxide-converting it into energy-along with other gases, including volatile organic compounds (VOCs) like benzene and formaldehyde. "I keep a peace lily in my bedroom, another in the living room with a couple of snake plants, and ivy in the bathroom," says Melissa Ozawa, a former garden and features editor at Martha Stewart. One of her go-to online plant sources is Glasshouse Works, where users can learn more about the holistic benefits of any plant. Here are some of the more effective varieties to bring home.

Peace Lily (Spathiphyllum 'Mauna Loa')

These are perfect for homeowners who enjoy bouquets of flowers, but not the upkeep. This resilient tropical plant, recognizable for its pristine white blossoms, is pretty and incredibly powerful: It removes benzene (found in plastics and synthetic fibers), formaldehyde (in carpets and upholstery), trichloroethylene (in adhesives and paint removers), xylene, ammonia, and more.

Chinese Evergreen (Aglaonema modestum)

This popular houseplant cleans the air in your home and is especially easy to grow and maintain. As a tropical foliage plant, it's great for a budding (pun intended) gardener as it tolerates poor light, dry air, and drought. The best part: It's efficient at removing benzene and formaldehyde.

Spider Plant (Chlorophytum comosum)

This "spider-like" plant, often potted in a hanging planter, gets its name for its long, droopy leaves. Spider plants eliminate formaldehyde as well as xylene and toluene, the latter of which are both found in many household products. This air-cleaning plant is also pet-safe.

This plant grows slim, ribbon-like stalks with red edges and can grow quite tall. Another powerful purifier, it eliminates benzene, formaldehyde, trichloroethylene, xylene, and toluene.
