Indoor plants have been proven by NASA to reduce indoor air pollutants. They can soak up formalyhede, xylene/toluene, benzene, tricholorthylene, choloform, ammonia, alcohols, and acetone. The best part is that they render these chemical harmless by breaking them down into nurtients (as opposed to carbon dioxide, which is released when the plant dies).

Here are fifty plants that have been proven to remove chemicals from the air; there may certainly be others, so any household plant is a good idea.
