 In the late '80s, NASA studied houseplants as a way to purify the air in space facilities. They found a range of plants that filter out common volatile organic compounds. In the same way, these plants can help clean the indoor air here on Earth, which is typically far more polluted than outdoor air and not only can they remove airborne contaminants but some are also nutritious herbs for both medicinal and cooking use.
