I recently tried a new workout that was really great. It was fun and went by quickly and I was the perfect amount of sore the next day. Much as I liked it, I can’t go back. You see it was a brand new studio, built with typical construction materials and new carpet. The “new room” smell was so strong, it felt a bit like taking a toxic steam bath. Every time the teacher reminded us to breathe deeply, I sort of cringed. The nasty effects of indoor air pollution are certainly cringe worthy. Of course it is best to avoid toxic materials whenever you can, but indoor pollutants are introduced into our homes and workspaces in ways we don’t often recognize. Common pollutants such as formaldehyde are found in common items such as paper products, inks and furnishings. Happily there may be some help in keeping our air clean and it is beautiful.
While researching how to create breathable environments in space NASA began testing common houseplants as air cleaners. In their study, various plants were put inside a sealed chamber into which chemical toxins were injected. After 24 hours, under these controlled conditions certain plants were found to remove up to 87% of the indoor air pollutants.
An increasing amount of corroborating research also indicates the benefit of live plants to improve indoor air quality. In his own research, Kamal Meattle used Areca Palms, Mother-in Law Tongue, an Money Plants in his office building. He found after adding the plants there was a 34% reduction in respiratory problems, a 24% reduction in headaches and a 52% reduction in eye irritation amongst the employees who worked there. There was also a 15% drop in energy usage since the need for air conditioning equipment was reduced. According to WebMD.com studies have shown that English Ivy placed in a container of moldy bread removed 60% of airborne mold in 6 hours and 78% was gone after 12 hours.
Here are a some of the top air cleaning houseplants:
1. Boston Fern
Boston Ferns are most effective at removing formaldehyde. Studies have also shown that they can remove heavy metals such as mercury and arsenic from the soil
2. Spider Plants
Removes carbon monoxide and nitrogen dioxide as well as formaldehyde
3. Areca Palm

4. Peace Lily
Very easy to grow with beautiful white blooms. Effective at removing benzene and trichloroethylene
Excellent at removing formaldehyde
6. Snake Plants or Mother of Law Tongue
