For wood-stove smoke, choose a portable air cleaner by its verified tobacco-smoke CADR, not by a broad room-coverage claim or a pollen rating. As a rule of thumb, the U.S. Environmental Protection Agency (EPA) recommends smoke CADR of at least two-thirds of the roomโs floor area in square feet, assuming an 8-foot ceiling. That can reduce airborne particles, but a particle filter does not remove every harmful component of wood smoke.
What an air purifier canโand cannotโdo for wood smoke
Wood smoke contains fine particles, including PM2.5, as well as carbon monoxide and other toxic air pollutants, according to the EPAโs wood-burning appliance guidance. A portable air cleaner with an effective particle filter can reduce airborne particle concentrations indoors. It should not be treated as a device that removes all gases or makes a smoke problem harmless.
Results depend on the cleanerโs size, filter efficiency, room area, how often it runs, and the fan speed used. EPA notes that it does not endorse manufacturer claims of healthier indoor air from a product; see its Guide to Air Cleaners in the Home.
How to size a purifier by smoke CADR
CADR, or clean air delivery rate, is a measure of how quickly an air cleaner delivers filtered air. For small smoke particles, compare the tobacco-smoke CADR. EPAโs sizing rule is a smoke CADR of at least two-thirds of the roomโs floor area in square feet, assuming an 8-foot ceiling. It is a practical rule of thumb, not a guarantee of a particular indoor concentration.

Apply the rule
- Measure the roomโs floor area in square feet: length multiplied by width.
- Multiply that area by two-thirds to find the minimum smoke CADR to target under EPAโs 8-foot-ceiling assumption.
- Check the cleanerโs verified smoke CADR and choose a model that meets or exceeds that figure.
- If the ceiling is substantially higher than 8 feet or the space is open to adjoining rooms, treat the floor-area estimate cautiously; the cited rule does not establish an adjusted CADR for those conditions.
For example, a 300-square-foot room gives a rule-of-thumb target of 200 smoke CADR (300 ร 2/3). A larger CADR may provide more airflow, but actual performance still depends on placement, operating speed, and room conditions.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Use filtration alongside source reduction
An air cleaner is one part of reducing exposure, not a substitute for preventing smoke from entering the living space. EPAโs wood-burning guidance discusses practices that can reduce emissions. If smoke is persistently leaking indoors or the appliance appears to be malfunctioning, address the source rather than relying on a purifier alone.
