Clean the air in your home with common houseplants. Though the amount of oxygen a plant produces differs depending on the size and growth speed of a plant, when tested some houseplants turned out to have the strongest air-purifying properties, pumping up oxygen in exchange for carbon dioxide while removing pollutants like formaldehyde and benzene from the air. As few as 15 houseplants can significantly improve the quality of air inside a home of average size.
The spider plant is a common, easy-to-grow houseplant that landed one of the top spots in NASA's list of air-filtering plants. The spider plant has green and white leaves, and produces little shoots that can root in nearby soil. The spider plant is perfect for beginners because it thrives almost anywhere, even in poor growing conditions.
The peace lily is a common gift at spring festivals or for Easter. It is also given as a gift plant for funerals. The peace lily is known for cleaning formaldehyde from the air and is known as a prolific oxygen producer. A delicate plant, the peace lily prefers well-drained soil, a great deal of humidity, low sunlight, and daily misting from a spray bottle. The peace lily is poisonous to eat and should be kept away from pets, especially cats.
The chrysanthemum is a flowering plant that is a common harvest gift. Its flowers are round and spiky and are usually white, orange, red or yellow. Chrysanthemum do not usually grow year round, and the buds must be cut off to allow the plant to return the next year, a process called deadheading. According to Cat Fanciers' organization, chrysanthemum can be poisonous to cats and should not be grown where cats are left alone.
