The following air purifiers are effective at removing cigarette, cigar and pipe smoke. When dealing with smoke, one of the most challenging air pollution problems, reduce the air purifier's recommended square footage by at least half.
NOTE: Surround Multi-Tech Ionizers and the Air Oasis Xtreme are great for one or two light to moderate smokers. For heavier smokers or a room full of smokers, you would need several Air Oasis 3000 Xtremes and/or the Airpura T600.
If the space has had heavy smoking for a long period of time, it could take several weeks or months to completely remove the odor from carpeting, window treatments and furniture.
