A former NASA scientist, B.C. Wolverton, has spent 30+ years (most of which was done with NASA) researching how plants can clean the air (and water) in indoor systems. If you would like to read some information on the research has done, click here. He wrote a book in the late 90’s, How to Grow Fresh Air: 50 House Plants that Purify Your Home or Office. This book describes how the plants clean the air and highlights house plants that he has found to do a good job at cleaning the air.
I haven’t read the book yet (I just found out about it while researching how to naturally clean your indoor air) but will be purchasing it the next time I pass my local book store. This seems like a perfect fit to my needs. I hate to buy a separate air purifier that would require more energy use. Anyway, who doesn’t love to have plants in all the rooms of their house? Bring the garden inside and help create a healthy living environment!
