If you’re a smoker or dealing with secondhand smoke and looking to keep the air in your home clean, investing in a high-quality air purifier with activated carbon is the best bet. Cigarette smoke is different from wildfire and wood smoke in that it contains a fair amount of tar, which is a liquid, that sticks to everything, is difficult to clean up, and is absorbed by fabrics such as carpets, window coverings and furniture. However, a HEPA filtration device, with significant carbon, can help.

These air purifiers for smokers can help tremendously with smoke and the bad-smelling odors that come along with it. Although the best method of maintaining clean indoor air is to eliminate the source of smoke, HEPA air purifiers can significantly reduce smoke and smoke odors in your home.

How so? HEPA filters are designed to catch more than 99 percent of smoke particles and activated carbon that is 0.3 microns in size or smaller. If you’re currently shopping for an air purifier, it would be wise to shop for units that have at least two or more pounds of carbon for light smoke. If you are a heavier smoker, you will need at least five pounds of carbon or more to absorb and remove smoke and its smoke odors.
