Winter means you’ll likely spend most of your time indoors, so it’s important to make sure you’re breathing in the cleanest air possible to avoid illness and stay comfortable. An air purifier is a reliable and relatively affordable way to help rid your home of excess dust, pollen, and other allergens quickly and efficiently, but the best options tend to cost a pretty penny.

If you’re overwhelmed with choices, you can’t go wrong with the Levoit Core 300 Air Purifier while it’s on sale for just $79 — its lowest price in history, according to Amazon price tracker camelcamelcamel. It’s the no.1 bestseller in Amazon’s HEPA filter air purifiers category and is backed by over 98,000 five-star ratings. Ideal for small spaces up to 1,095 sq/ft, it’s a great option for bedrooms and offices. Since it only weighs 7.48-lbs, it’s easy to move from one room to another, too, so you can use it practically anywhere there’s a power source.

This machine might be small, but it packs a powerful punch considering it starts cleaning the air in as little as 12 minutes using a high-torque motor and VortexAir technology with 360-degree air intake. In under an hour, it’ll purify the air in an entire room, passing it through its three-stage filtration system to remove even the smallest particles, including pet odors, dander, smoke, and pollen. It includes a pre-filter, efficient filter, and activated carbon filter, and the entire filter should be replaced at least once every six months to prolong the life of the air purifier.

Thanks to its user-friendly LED display, adjusting settings is a cinch and doesn’t require any guesswork as everything is clearly labeled. Choose between three fan speeds, set timers, turn on night mode, and dim its lights at the touch of a button.

This specific unit has been purchased more than 80,000 times in the past 30 days, which isn’t a surprise considering it’s at a record-low price right now. Many shoppers claim the air purifier makes a “significant difference” in their quality of life and others call it one of the “best purchases” they’ve ever made.
