Q. Do plants clean the air?


Yes, plants do clean the air by removing toxins indoors. In the 1970s, NASA conducted extensive studies of many houseplants to determine whether plants improve air quality and by how much.  Their results showed that many plants do improve indoor air quality to varying degrees.

For more information on plants that improve indoor air quality, see our Plant Information guide, Clean Air With An Indoor Garden.
