An illustrated guide to the houseplants you need for clean and fresh airwhen you’re stuck at home

In this beautifully illustrated guide, noted scientist Dr Bill Wolverton shows you how to grow 50 plants that filter the most common pollutants, making it easy for you to purify the environments that impact you the most.
