Best air purifier for wildfire smoke in 2022

After firefighters contain a wildfire, you may have to deal with the resultant ash or smoke if you live around the area. This can be quite a challenge.

Depending on the severity of the fire, it may take weeks or months to clear the air of the pollutants. That may cause long-term health complications since you will be breathing in the ash or smoke that remains.

To protect yourself and your family, you need to use the best air purifier for wildfire smoke that can remove smoke particles from the air.

Smoke contains particulate matter and carbon monoxide that is hazardous to human health. To avoid breathing them, you need an air purifier specially designed to filter out smoke, especially thick forest fire smoke.

Most of the units available today are effective at reducing carbon monoxide and particle pollution, but very few can handle thick smoke. That’s why we have created this guide -to help you settle for the best device. But first, here are a couple of things to keep in mind.

Things to consider when choosing air purifiers for wildfire smoke

How many microns is wildfire smoke? That is the first thing to determine before buying an air filter. Ideally, particles from smoke can be small, between 0.4 and 0.7 microns. Thus, you need a unit that can trap particles as small as 0.3 microns. Also, consider the following factors.

  • HEPA Filter – An HEPA filter reduces particle concentrations by 85%.
  • CADR of 200 – Its Clean Air Delivery Rate rating should be at least 200. The rating will measure the volume of air that can pass through the unit and it is helpful in determining the efficiency of the model.
  • MERV of 12 or higher – Its Minimum Efficiency Reporting Value should be 12 or higher. It will be more effective at controlling most airborne indoor particles.
