Indoor plants that clean toxins out of the air [1]

While many people are quite careful about the kind of food they eat and the water they drink, what about the air you breathe? If you live in a modern house, chances are there's any number of toxic chemicals in the air. There's benzene [2] and xylene [3] from car exhaust, toluene [4] from paints, and things like formaldehyde [5] and ammonia [6] that come from a large variety of sources. Fortunately, there's an easy and effective way to clean the air that's been used for hundreds of millions of years: plants. Research at NASA and other sources was collected to produce the following list of plants that show a remarkable ability for filtering toxic chemicals out of the air:
