Plants to Filter the Air in Your House
Having good indoor air quality is very important, especially since many of us spend so much time inside. NASA did a study to find out which plants were best to filter the air of the space station, and their findings are available to all.
Read on to see which house plants are best to filter the air (not only producing Oxygen from CO2, but also absorbing benzene, formaldehyde and/or trichloroethylene.

Via Wikipedia:
The NASA Clean Air Study has been led by the National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA). Its results suggest that certain common indoor plants may provide a natural way of removing toxic agents such as benzene,formaldehyde and trichloroethylene from the air, helping neutralize the effects of sick building syndrome.
