Here's another reason to give houseplants a try for your home: They purify the air. According to a story by NASA, common indoor houseplants can remove up to 87 percent of toxins from the air. They do this by absorbing the pollutants through their leaves and release breathable air back into the atmosphere. Also, don't forget about places where you work. Adding just one plant to your workspace can clean about 100 square feet of space, which is about the size of the average cubicle in America. Anything you can do to reduce the toxicity in your home and workplace is a good thing, and one simple plant can be that solution.
