Air Purifiers and Tobacco Smoke
Secondhand Tobacco Smoke and Air Purifiers
Exposure to environmental tobacco smoke, also known as secondhand smoke, significantly increases the risk of lung cancer and heart disease in non-smokers, as well as contributing to respiratory illnesses. We agree with this advice from the Mayo Clinic: “The best way to protect non-smokers from secondhand smoke is to not allow smoking in your home.” Still, the best solution isn't always possible and that's where an air purifier can help.
Tobacco smoke contains more than 4,000 different chemicals, 60 of which are known carcinogens. These various elements are a mix of liquids, gases, and solid particles. An air purifier cannot help protect against tobacco smoke unless it provides a high level of efficiency against both particles and gases. On the other hand, a high-efficiency air purifier with the right filtration media can help dramatically. The IQAir GC MultiGas air purifier, which offers unrivaled protection against both particles and gases, is the recommendation of most experts.
The positive effect of air purifiers in homes where secondhand smoke is an issue has been demonstrated. For example, The Johns Hopkins University School of Medicine recently reported that an air purifier can be as effective as drugs in reducing asthma attacks among children in homes where one or more parents smoke. On average, the children in the study suffered 33 fewer days per year enduring severe asthma symptoms.
Note: IQAir does not endorse smoking indoors. IQAir views air cleaning as a means in reducing the effects of secondhand smoke only when smoking is unavoidable. In an environment where smoking indoors in unavoidable, smoking should be confined to only one room.
