For sufferers of seasonal allergies, air purifiers can make a big difference, filtering such airborne pollutants as dust particles, smoke particulates, pet dander, pet hair, pollen and mold spores from your indoor air. This can have a profound impact on your quality of life, from assisting in dust removal to eliminating pet odor to minimizing the effects of air pollution in your home. Air purifiers are also one of the best ways to remove virus particles from the air inside your home, something on many more people's radar due to COVID-19.
With a multitude of different machines on the market that all tout various methods of purification -- you could invest in an ionic air purifier, a purifier with an activated carbon filter or even a full home filtration system. It can be tricky to shop for the best air purifier for your needs on your own, but CNET is here to help you sort through your options. These are three of our favorite models for different size rooms and homes.
Best air purifier for large rooms
Blueair Blue Pure 211 Plus
CNET TAKE: Blueair's excellent large-room air cleaner looks great, runs fairly quietly and — most importantly — cleans large rooms efficiently. The Blue Pure 211 Plus weighs 13 pounds and has a simple interface: The touch-sensitive button on the front of the device lets you set it to low, medium, high or off. That's it.
While it would be nice if it had a few more smarts, like an automatic setting that responds to air quality, Blueair has invested where it matters: the cleaning technology. The True HEPA filter is certified to clean the air in spaces up to 560 square feet, and the activated carbon filter helps remove odors, too. That much power for $300 is pretty impressive.
Best air purifier for midsize rooms
Honeywell Home HPA300
