Best premium air purifier deal

Amazon’s Big Spring Sale is nearly here, but if cleaner indoor air is already high on your shopping list, you do not need to wait for the official kickoff date of March 25 to 31 to start saving. A couple of standout air purifier deals are already live at Amazon, including one option built for extra-large rooms and another premium model that doubles as a heater and fan.

There’s also already early spring sale deals on Amazon Echos, budget TVs, and even robot vacuums. In the meantime, though, whether you are dealing with spring pollen, pet dander, smoke, or just want to freshen up a stuffy room before allergy season really ramps up, these early offers are already top contenders worth your time, considering, at the very least. 

As of March 18, the Sharp FXJ80UW is the better pure value pick, while Dyson’s Purifier Hot+Cool HP1 makes more sense if you want an all-in-one appliance that can stay useful beyond spring — though there are also plenty of other offers from a wide variety of brands below as well.  

Best Amazon Big Spring Sale air purifier deal $299.99 at Amazon
$499.99 Save $200

Why we like itAt $299.99, this Sharp model is discounted by 40%, which chops a full $200 off its $499.99 list price. That is a serious drop for a purifier designed for extra-large spaces, with coverage of up to 2,430 square feet in one hour and an AHAM suggested room size of 502 square feet at 4.8 air changes per hour.

Sharp is giving you a lot for the money here, as the FXJ80UW pairs a washable pre-filter, activated carbon deodorizing filter, and True HEPA filter that captures 99.97% of particles 0.3 microns and larger, while also adding Plasmacluster ion technology for more active air cleaning. It also works with the Sharp Air app and supports Alexa and Google Assistant, which makes it feel a lot more premium than its new under-$300 price would have you believe. 

Even better, Sharp says its HEPA and carbon filters can last up to two years, depending on the environment, which could help soften long-term upkeep costs.

Best premium Amazon Big Spring Sale air purifier deal $499 at Amazon
$659.99 Save $160.99

Why we like itIf you want something more versatile, the Dyson Purifier Hot+Cool HP1 is down to $499 from $659.99, saving you $160.99 — which price tracker camelcamelcamel also confirms is its lowest price ever. While this is more of a premium investment, it’s easier to justify when you remember this is not just an air purifier — but effectively a room heater and air conditioner, too.

The HP1 combines HEPA and activated carbon filtration with whole-room heating and fan cooling, so it can stay in use year-round instead of being dragged out only when allergy season hits. Dyson says it captures 99.97% of microscopic allergens and pollutants as small as 0.3 microns, while also removing 97% of odors such as cooking smells, pet odors, and smoke. 

You also get app controls, voice compatibility, auto mode, night mode, and oscillation up to 350 degrees, which makes it a sleek option for shoppers who want cleaner air without adding yet another appliance to the room.
