The Black Friday and Cyber Monday sale is a perfect time to invest in one of the best air purifiers. With the temperatures dropping and days getting shorter, we tend to spend far more time in the cosy solace of our homes with windows and doors firmly shut — this is where good air quality can make all the difference. Good air purifiers will keep the air in your indoor home free of bad smells and common winter pollutants, such as dust mite allergens, pet dander and mold spores. Not to mention, they typically hit their lowest-ever prices. It is a no-brainer.
But exactly which air purifier should you buy? That's where we step in. We have been testing and reviewing air purifiers for years, so we know which are best suited for people with allergies and which do the best job around pets. We track prices daily, so if the price changes, we know by how much and whether it has been better before. Rest assured, if there is an air purifier deal to be had, you can find it here.
Editor's note, December 1: Hurry, the deals end at midnight!
