Ditch plastic plants for the real thing. A few houseplants -- like ivy and even cacti -- will help naturally filter the air in your home by absorbing bad gases like formaldehyde and benzene all while absorbing CO2 and giving back oxygen. Ask your local nursery for drought-resistant plants if you have more of a brown thumb with live plants or look for beneficial plants such as aloe vera, which can have medicinal properties, too.
