List of recommended plants for cleaning indoor air

In the 1980s, NASA studied house plants and their ability to cleanse indoor air. For a 1,200 to 2,000 square foot home, use 10 to 15 plants. These plants will go a long way to help clean indoor air of pollutants, such as carbon dioxide and formaldehyde. Place them where you spend the most time, such as on a desk or reading table.

Here are 15 plants recommended for the job, each of which should be available at florists, garden centers and other retailers.
