NASA researchers set out to find the best ways to clean the air in space stations.  Plants act as filters because they absorb toxins through leaves.  Chemicals left behind from household cleaners, air fresheners, paint, upholstery, etc. have been linked to allergies, asthma, neurological disorders and more. Using plants that are known to absorb the worst chemical offenders is an affordable and natural way to filter the air in your home.

Considering studies show that indoor air is 100 times more polluted than outdoor air, and that Americans spend ninety percent of their lives indoors, it follows that good indoor air quality is vital for good health.




Houseplants bring in humidity and oxygen, but some of them are more effective than others at filtering out pollutants and toxic chemicals in the air.  Cacti is known to absorb electromagnetic radiation from computers, so bring in some cactus into your office.

scientist Dr. B.C. Wolverton discovered that houseplants are the best filters of common pollutants such as ammonia, formaldehyde, and benzene. Hundreds of these poisonous


chemicals can be released by furniture, carpets, and building material, and then trapped by closed ventilation systems, leading to the host of respiratory and allergic reactions now called Sick Building Syndrome.


How to Grow Fresh Air will show you how to purify the environment that has the most impact on you.


Researchers from NASA and other organizations recommend at least 15-18 good-sized plants for a house or apartment of 1800 square feet or 167 square meters.
