You may not realize that the indoor air you're breathing right now is laden with formaldehyde, benzene and other chemicals that could kill you. They're called Volatile Organic Compounds, or VOCs, which are emitted by carpet, air fresheners, paints, cosmetics, even newspapers. They can cause serious health problems, including asthma and cancer, and are responsible for more than 1.6 million deaths each year, according to a World Health Organization report.
Luckily, common house plants absorb VOCs in indoor air -- some better than others. Both NASA and the University of Georgia have experimented with dozens of house plants to determine which is the best at scrubbing VOCs from the air you breathe.
We've culled the lists to find the top eight that provide a breath of fresh air to your home:
