Chemicals are fairly prevalent in our homes, but house plants can help! A 1989 study by NASA (get the PDF here) concluded that certain "low-light-requiring houseplants, along with activated carbon plant filters, have demonstrated the potential for improving indoor air quality by removing trace organic pollutants from the air in energy-efficient buildings." The study identified 10 plants that purify indoor air of dangerous toxins, including trichloroethylene, formaldehyde, and benzene.
Luckily, by adding some good-looking plants to our homes that are proven to purify the air, we can greatly reduce our exposure to these scary chemicals. Want to know what the top 10 air purifying plants are?
