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, which can filter out smoke, pollen, dander, hair, and even smells. If you’re worried about the noise, you can turn on the sleep mode, which will reduce it to the lowest speed to give you peace and quiet while it still works through the night. It covers up to 215 square feet, so it’s perfect for a small bedroom or office.
