Because tobacco smoke particles range from .01-4 microns in size, it is critical that you get a purifier that utilizes a filter capable of trapping particles of this size. The best air purifiers for smoke will have a filter capable of trapping particles down to .01 microns with good efficiency and will contain additional filters designed to address the gaseous components of tobacco smoke which contribute to the odor and are toxic. The best solution for this is a large quantity of high grade activated carbon. This is one area where many companies skimp and if you want true effectiveness with odor and gaseous toxin removal, there must be enough carbon to absorb it all. While not many purifiers can trap particles .01 microns big, you will ideally want a HEPA filter that is capable of trapping particles smaller than .3 microns a HEPA filter is typically capable of. The following purifiers are our picks for the best air purifiers for smoke and are designed for different square footages and are offered at varying price points.You can browse other offerings by the same brands to potentially find a better square footage/price match for your needs.
This unit is not only capable of trapping all of the smallest particles in the air (down to .003 microns!) but also features a V5 gas absorbing filter which is excellent. This really is the best of the best.
The Blueair 603 is capable of trapping particles down to .1 microns in size and has a great CADR (Clean Air Delivery Rate) for smoke of 415! Blueair also offers their SmokeStop filter which adds a good quantity of highly active and very efficient carbon pellets into the purification process.
This unit offers several filtration technologies to work against smoke and its nasty byproducts. There is a true HEPA filter, an activated carbon filter and an ionizer. Lastly it offers a Photocatalytic oxidation (TiO2) filter which I have not see on any other units. This is capable of destroying a high percentage of the VOC’s in the air due to smoke.
