How To Grow Fresh Air

Author B.C. Wolverton originally began his research to investigate creating a breathable environment for a NASA lunar habitat. What came of that research was the discovery that houseplants are the most efficient filters of common pollutants such as ammonia, formaldehyde and benzene. (See our list of the top plants for cleaning the air).

In this well laid-out book, Wolverton presents 50 plants that are ranked on removal of chemical vapors, ease of maintenance, resistance to insect infestation, and transpiration rate. Each plant gets a two-page spread — one page discusses the plant’s ideal environment, sunlight conditions, care, and general information about the plant along with a full photo of it. The next page has a zoomed-in full-page photo of the leaves and/or flowers so the reader gets a feel for what the plant looks like.

How To Grow Fresh Air is available from Amazon.
