Best Air Purifiers for Smoke (2026)

Smoke is hard for an air purifier. The EPA says smoke is a mix of gases and fine particles, and the fine particles are the biggest health threat. Here are four picks, and every number is the maker's own. We do not test products. This page is not medical advice.

The one rule for smoke purifiers

You want two filters: HEPA for particles and activated carbon for gases and odor. The EPA says the CADR rating is for particles only. It also says carbon filters work when there is a large amount of carbon. A thin carbon sheet holds very little. And the EPA says to make sure a portable air cleaner does not make ozone.

When Wildfire Smoke Rolls In

The EPA says to keep windows and doors closed. Set your central air to recirculate, or close the fresh air intake. Put a portable air cleaner where people spend the most time and run it on the highest speed. When the air gets better, even for a short time, air out your home.

Common Questions

Do I need activated carbon to remove smoke?

Yes, if you want to cut smoke gases and odor. HEPA is made for particles. The EPA says a HEPA filter can, in theory, remove at least 99.97% of particles 0.3 microns in size. The EPA also says the CADR rating is for particles only. Activated carbon is the filter for gases. The EPA says carbon filters can work when there is a large amount of carbon in them.

How much activated carbon do I need?

No one gives a single number. The EPA says carbon works when there is a large amount of it. So compare what the makers state. IQAir says the GC MultiGas XE holds 12 lbs of activated carbon. Austin Air says the HealthMate Plus holds up to 15 lbs of carbon and mineral media. Blueair and Coway list carbon in their filters but give no amount.

What CADR do I need for smoke?

The EPA says to pick a CADR large enough for the room. Its chart, for 8-foot ceilings: a 200 sq ft room needs a CADR of 130, 300 sq ft needs 195, 400 needs 260, 500 needs 325 and 600 needs 390. AHAM's 2/3 rule says the smoke CADR should be at least two-thirds of the room's area. On the EPA chart, the Blueair 211i Max's smoke CADR of 435 is above the 600 sq ft row.

Can an air purifier handle cigarette smoke in a whole apartment?

It can help, but it will not remove everything. The EPA says air cleaners cannot remove all pollutants from the air. For smoke gases and odor, look for a lot of carbon, like the IQAir GC MultiGas XE or the Austin Air HealthMate Plus. Size it to the room with the EPA chart.

Should I run an air purifier on high during wildfire smoke?

Yes. The EPA says to put a portable air cleaner where people spend the most time and run it as often as possible on the highest fan speed. AirNow says portable air cleaners work best when run all the time with doors and windows closed. If you have central air, the EPA says to use a MERV 13 filter or as high as your system allows.
