I encounter some of the most environmentally sensitive patients who react to the smallest airbome allergens. For the last ten years I have been researching and investigating the air purifying industry. As a Doctor with an environmental health practice, I have had to researc{ and investigate the answers to these questions for many of my patients. | found none of them being more effective at clearing cigarette and cigar smoke from a room, removing allergens from the air, or removing smoke from a public place like a bar. The only others capable of killing germs are substantially more expensive
