I love plants and keep my house filled with them as they help to cleanse the air and keep the family healthy. They help to reduce carbon dioxide levels, reduce levels of pollutants like benzene, formaldehyde and nitrogen dioxide and can be helpful in reducing airborne dust levels.
In 1989, Nasa published a list of air filtering plants as part of their Clean Air Study. They studied houseplants and found that they were a good way to purify the air in space. Nasa noted that plants "provide nourishment for the body when eaten as food and they improve the quality of indoor air. Plants take the carbon dioxide from air to produce oxygen that humans can breathe."
