I borrowed this book from the library, and am thinking of buying a copy to keep. It gives just enough details and technical information to be clearly understood without being so technical that you have to be a rocket scientist to understand it. I was pleased to discover that I actually have several of the plants that it recommends and am planning on buying a few more now that I know more about the hazards of indoor air pollution and the positive role that these plants play in removing it.
I've had this book for a long time, but not without almost losing it to friends several times. It's a wonderfully clear and interesting book about how houseplants improve the air in our homes, not only by filtering out chemical pollutants, but by regulating humidity and discouraging microbes. It tells you which plants are best for which chemicals and gives tips on hydroponic gardening. Most of the book consists of plant-by-plant descriptions. I love this book!
