List of the best air purifiers for wildfire smoke.

Although inhaling a small amount of fire smoke should not be a problem for a healthy person, I believe it is better to prevent a potential health problem; nevertheless, you should work on a solution and neutralize the smoke in your home. 

Smoke from forest fires is unpleasant as it can cause burning eyes and run from the nose. In addition, inhalation of harmful substances can damage the lungs and even cause permanent damage.

With the rise of the air purifier market, users have realized their potential in removing smoke and the opportunities these devices offer. However, buying an air purifier is not an easy task either, and there are a few things to look out for before you buy it. For starters, you should pay attention to the fact that the air purifier uses a certified True HEPA filter or another HEPA filter rated MERV 13 or above. 

Why a True HEPA filter? 

Because a True HEPA filter neutralizes particles up to 0.3 microns in size, fire particles are usually between 0.4 and 0.7 microns. This article will present my research and detailed suggestions on the best air purifiers you can buy for wildfire smoke.
