The 13 Best Air Purifiers on Amazon — Starting at Just $40

Levoit Air Purifier ($40, originally $50)

This is Amazon's bestselling air purifier, and it's easy to understand the appeal. It uses a 360-degree VortexAir Technology, has a three-stage filtration, and is quiet enough to keep in a bedroom. You can also purchase aroma pads and use a few drops of essential oil so that it doubles as a diffuser. This model has over 16,000 reviews and a 4.6 rating, so it's a solid choice for less than $50.

Aroeve Air Purifier ($50, originally $70)

Just under 10 inches tall and only six inches in diameter, this small air purifier still packs plenty of power. It uses an H13 HEPA filter to filter smoke, pollen, dander, hair, and smells. If you're worried about the noise, you can turn on sleep mode, which will reduce it to the lowest speed to give you peace and quiet while it works through the night. It covers up to 215 square feet, so it's perfect for a small bedroom or office. Shoppers love that there's an aroma pad below the purifier air outlet to add essential oils for fragrant air. One reviewer described this feature as "so easy to use" that they "use it more than our diffuser."

AIRTOK 2-Pack Air Purifier Set ($90 for two, originally $110)

They're both on the smaller side, and their compact size will fit on a side table or nightstand without interfering with your room's aesthetic. Each air purifier covers up to 376 square feet a piece, so it's best for smaller spaces. It has a touch panel that includes a variety of settings, including a two-, four-, or eight-hour timer and specific fan speeds. Plus, if the essential oil sponge piqued your interest in the last slide, this air purifier has one, too.

TruSens Air Purifier ($116, originally $229)

Read our editor's honest thoughts in our TruSens Air Purifier review.

Editor Quote: "Unlike anything else I've ever owned, this purifier comes with a remote SensorPod that is constantly measuring the air quality in your room and goes to work. This way it quietly works without you even having to pay attention to it. When we first plugged it in, it said the air quality in our room was between 20-30, and it went straight into turbo drive pushing new filtered air into our space. Within minutes, our air quality was down to 5, and I was impressed." — Krista Jones, former editor, Commerce
