Over the last several years we have seen a noticeable global decline in air quality as a result of pollution issues, wildfires and everything in between. Those who live in a densely populated city are especially at risk of exposure to pollutants in the air from cars and other sources. As such, air purifiers are a good solution to help deal with the worst of it, and whether you’re in an office or at home, getting some kind of purifier for your space can be a wise investment.
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. While there are several types of purifiers, we’ve found that some of the best have some form of HEPA filter, so we’ve done our best to factor 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, but another important aspect to consider before you buy one is the size of the space you want to filter. 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 purifiers that can filter air for the entire house. We will update this list regularly as deals expire and new offers drop at various retailers, so keep checking back.
