According to a 1993 report by the U.S. Environmental Protection Agency (EPA), secondhand smoke is classified as a Group A carcinogen, meaning there is sufficient evidence to conclude that it causes cancer in adults. Removing secondhand smoke from the air can help protect non-smoking adults and children from its toxic effects.

RabbitAir BioGS SPA-528A Ultra Quiet HEPA Air Filter
According to the EPA, purifiers that use a high efficiency particulate air (HEPA) filter remove respirable particles like pollen and dust, and carbon filters also trap and remove cigarette smoke and odors efficiently. The RabbitAir SPA-528A features a BioGS HEPA filtration made from advanced bio-engineered fiber material and an activated carbon filter to eliminate secondhand smoke due to heavy cigarette usage. Additionally, the SPA-528A emits no ozone, a substance that also may cause harmful health consequences.
While some air purifiers can be quite noisy, the SPA-528A uses a brushless "direct current" motor, a new technology that reduces decibel levels. The lowest of the five speed settings emits a mere 19 decibels of sound, softer than a whisper.
This air purifier can help remove cigarette smoke in a typical bedroom of about 780 square feet. It comes with a five-year warranty on parts and labor. RabbitAir offers 24/7 technical support. As of 2010, the SPA-528A can be purchased online for about $400.
