If you missed out on the best Prime Day air purifier deals back in July, we have some good news to share. With peak fall allergies coming into play (not to mention unpredictable climate aggressors continuing to arise), clean air is always something worth investing in. And if you’re an pet parent, love to cook, enjoy other recreational activities indoors, or just want to prepared for the next air emergency, it’s a smart idea to protect your lungs from dust, pet dander, and allergens.
Below we’ve rounded up some picks prime members can save big on during Amazon’s October sales event, Prime Big Deals Day, including some of the bestsellers from last Prime Day; air purifiers AD’s editors have already reviewed; and brands with advanced features like bluetooth capabilities, carbon filtration, and more. You can also learn more about our Amazon favorites, review our top choices for prime day deals under $100, furniture, mattresses, sheets, and bath towels too.
If you’re not quite sure what’s worth copping during the prime day sales extravaganza, a new air purifier is a good place to start.
