Living Air Purifiers (2)

It is well known any plant improves the air we breathe. Scientists at NASA did studies into which plants are most effective at purifying the air and two of the best performers were Aspidistra and Spider Plants. Not not only do these plants produce oxygen from carbon dioxide,they also absorbs impurities such as benzene, formaldehyde and trichlorethylene. The air inside homes and offices can be 3 to 10 times more polluted than the air outside because of the vapours given off by things like carpets and paints. The good news is NASA says you only need 3 houseplants to improve the air quality of a room or office up to 10 square metres in size.
