Air purifiers improve indoor air quality by removing fine particulate matter from the air. However, they can use up to 50% more electricity than a new refrigerator, and have not been proven to improve your health. Certain models also emit ozone that is harmful to the lungs. However, Energy Star certified purifiers do not emit ozone at dangerous levels, and are 35% more efficient than conventional purifiers. Check the CADR (clean air delivery rate) to Watt usage to measure efficiency. Below is a sample of Energy Star certified products. To see all Energy Star certified products, visit Energy Star
