Air quality can be a major problem these days, given recent wildfires, pollution and more. People living in densely populated cities are especially at risk of exposure to pollutants from cars and other sources, and using air purifiers is one way they can combat the problem, whether they’re in an office or at home.

Depending on the model you choose, different filtration systems can rid the air of numerous types of irritants, including pollen, smoke, dust, mold, pet dander and germs, and that can improve your overall respiratory health. The best part is you can grab one of these devices without stretching your budget too far. Though there are several types of purifiers, we’ve found that a number of the better ones have some form of HEPA filter, so we’ve factored that into our evaluation.

When buying an air purifier for your home or workplace, there are many aspects to consider, including size, price and features. Another important thing to look at is the size of the space you’re dealing with. If you buy an air purifier that’s too small for your room, you won’t reap the benefits. Keep that in mind as you shop. 

We’ve rounded up some of the best air purifier deals available and have tried to include discounted options for every environment, from the smallest rooms to an entire house. We’ll update this list regularly as deals expire and new offers crop up at various retailers, so keep checking back.
