Having clean air, especially in your home, is very important for your respiratory health. Indoor air quality can be degraded by many factors, including pollen, wildfire smoke, dust, mold, pet dander, vehicle emissions and other air pollutants. If you regularly find yourself affected by poor air quality, putting an air purifier in your home or office might help.

Many manufacturers make air purifiers these days, with filtration systems that are designed to tackle numerous types of irritants and germs (we've found that the better ones typically have some form of HEPA filter). 

Beyond filtration, you'll find a lot of variation in these devices, and many factors will go into picking which air purifier to buy, including size, style, price and special features. Another important thing to consider 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. So, keep that in mind as you shop.

With all this variety in products, you'll also see a big range in prices, with some air purifiers running several hundred dollars. The good news is you can often find deals that bring those prices down. 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.
