The best air purifier to use against cigarette smoke and odor
Top pick
GC MultiGas XE
IQAir GC MultiGas XE
Among single-unit options, the IQAir GC MultiGas XE is the strongest, since it handles smoke particles and also adds 12 pounds of carbon and chemisorption media for gases. The Austin Air HealthMate Plus carries more mixed gas media but does not publish CADR. No purifier makes indoor smoking harmless, and none replaces source removal and ventilation.

Up to 15 pounds of activated carbon, potassium-iodide carbon, mineral media and zeolite is documented by Austin Air.
The cabinet is 23 inches tall, has a footprint of 14.5 by 14.5 inches and weighs 47 pounds.
Neither an app nor a sensor is part of its three-speed controls and filtration path.
Handle smoke particles and smoke gases as two separate filtration jobs.
01
CADR is about particles
Airborne particles are what a high smoke CADR helps remove. Nicotine odors, VOCs and how fast carbon will saturate are outside what it measures.
02
Replace gas media before it looks dirty
A carbon bed may be used up with nothing visible to show for it. Heavy ongoing smoke cuts short any published normal-home interval.

Residue on walls and fabrics is beyond what portable filtration can remove

Key facts
In its documentation, IQAir gives 12 pounds of activated carbon and chemisorption media.
The room claim of 1,125 square feet rests on two air changes per hour, and maximum airflow is 275 CFM.
The catch
Given the cabinet size and price, a 275-CFM maximum airflow is modest.
Heavy and manually operated, this purifier combines HEPA filtration with up to 15 pounds of carbon, zeolite and potassium-iodide media for difficult gas loads.
Best forLingering smoke or chemical odors, where deep gas media is key and simple manual controls are fine
