These Top-Rated Air Purifiers Are the Key to Fighting Allergies and Air Pollution in Your Space (and They're All on Sale)

This super sleek Dyson isn't just an air purifier—it also functions as a heater and a fan, so it cleans, heats and cools your space with a touch of a button. Talk about multitasking. More importantly, though, is the fact that its activated carbon filter and glass HEPA filter work together to capture 99.97 percent of particles as small as 0.3 microns, per the brand, so cleaner air is guaranteed. And, just to be sure, you can actually moniter air quality in real time on its LCD screen and the MyDyson app. "Also wonderful to know that the next filter I will use on this device was included in the [QVC] sale price," one buyer adds. (P.S. First-time QVC customers can also use coupon code NEWYEAR15 to score an additional $15 off through Jan.31.)

A great choice for smaller spaces (up to 337 square feet), this compact filter has a stamp of approval from more than 38,000 5-star reviewers. While it's designed to capture lint, hair, pet dander, fine airborne pollutants and smoke particles, buyers are mainly obsessed with its Activated Carbon Filter that supposedly works like a charm to neutralize odors, from smoke to food. But I'll let one buyer tell it: "Since I bought this, my nights are now incredibly better. My flatmate likes to cook, and during winter, the smoke/smell gets trapped in the house, and just turning it on makes my room free of any smell. Also, sometimes I would struggle with allergies to sleep and not anymore." Need I say more? Better hurry up and buy it while it's under $50!

This air purifier is great for non-tech-savvy folks. Here's why: Thanks to Clean Sense IQ, it senses air quality and auto-adjusts it accordingly to constantly purify spaces up to 500 square feet. So, basically, it does the work for you. And according to the brand, it has a 99.98 percent filtration efficiency for capturing and clearing even the tiniest airborne particles, including pollen, dust and pet hair, so prepare to breathe cleaner air all year long. And I didn't even mention the fact that the filter only needs to be replaced every six to 12 months, so it's as low maintenance as it gets.
