For those who use Air Cleaners to help with at-home cigarette smoke, there are some issues you should be aware of:
1. Air cleaners are generally effective at removing the particles found in tobacco smoke. This is a good thing, as one of the chief concerns is deep inhalation of such particles.
2. Some Air Filtration systems release scent into the air to mask odors, but some do not. You may discover that an offending ashtray smell lingers because of the odors from the cigarette ash is not being masked by the scented air.
3. Cigarette smoke odor is not caused by the particles removed by an Air Cleaner, it is caused by gases which may not be purified with your particular make and model of air filtration system.
If you still smell smoke when using your Air Cleaner, remember that the odor is not an indication of a bad air filter! When in doubt, clean the filter or replace it, but keep in mind these additional factors when it comes to cleaning up the air after a smoker.
