NASA-approved houseplants for cleaner indoor air

You don’t need exotic technology or expensive gadgets to remove pollutants from the air you breathe indoors. According to NASA studies, a selection of hardy, easy-care houseplants can help. NASA has been researching methods of cleansing the air so that future space stations can be kept fit for human habitation for extended periods of time. Researchers have discovered that many common houseplants “scrub” significant amounts of harmful gases– such as formaldehyde and benzene– out of the air through photosynthesis, absorbing pollutants and rendering them harmless in the soil.
