It’s the second day of Amazon’s major October sale and the sale is coming to an end. Nevertheless, our team at CNN Underscored has been on the hunt for the best deals worth your time and money.

With the seasons changing, you’ve probably been plotting how to stave off allergies and colds, especially before your next Halloween party, Friendsgiving or holiday celebration. Let’s be real, no one wants a sniffly guest at their next gathering.

An air purifier is a game-changing appliance that can filter particles from your home to improve air quality and help you breathe better. Better yet, it can also cleanse the air of airborne viruses. I’m not only a shopping editor who’s gone hands-on with countless products, but also an air purifier user of three years who can safely say that having one has been a (literal) breath of fresh air. It filters air in my stuffy studio, removes dirt and other particles and helps improve my sleep too. Trust me, those unseen particles in the air make a big impact, so you’ll want to make sure your home is full of fresh, clean air.

While Prime Big Deal Days winds down, I’ve scoured Amazon’s air purifier selection to find the best deals, so read on to shop my top picks.
