Can Air Conditioners Remove Smoke?

It’s necessary to keep your home’s air quality in check all the time, but it’s especially crucial during times of extreme air pollution, heavy dust, or nearby bushfires. Smoke from bushfires can linger for days, even weeks after the fire has been extinguished, depending on the wind and rain.

Using Your Air Conditioning System To Reduce Smoke In Your Home:

Does Smoking Damage Air Conditioners?

Tobacco smoke contains carcinogenic particles that can linger in the air for weeks, months, or even years. If you smoke indoors while the air conditioner is on, there is a good chance that the smoke particles will be sucked up by the system and released back into the room for days, even months.

You may need to maintain changing the filter as often as once a month if you smoke a lot of cigarettes in your room.
