How to Grow Fresh Air: 50 Houseplants that Purify Your Home or Office
by Dr. B.C. Wolverton

Book Description (from the publisher)
Plants are the lungs of the earth. This revolutionary guide, based on 25 years of research by NASA, shows how common houseplants can combat sick building syndrome and cleanse the home or office of common pollutants. Highly informative, and fun to browse through. This is a great new book on the rarely discussed subject of using houseplants to clean indoor air. The book starts with a few well written and illustrated chapters on indoor air pollution, sick-building syndrome and the process by which plants can help. The remainder of the book discusses 50 common plants and outlines the care and needs of each one, as well as each plant's ability to clean various toxins from the air. Not only is this an informative book, but it's fun to read, and beautifully photographed and designed, with lots of excellent full-page color photography.
