The 13 Best Amazon Air Purifiers — Starting at $40

Coway Mighty Air Purifier ($207, originally $230)

This air purifier is a popular choice that customers and editors love. It's small, lightweight design can simply tuck away, so you'll forget it's even there. Its best feature? Eco mode (which you'll hear more about in a sec). Our former editor says it helped clear her stuffy nose, and you can read all about it in this Coway Mighty Air Purifier review.

Editor Quote: "It's also sleek, and you can easily tuck it away. My favorite feature, though, might be Eco Mode: when no pollution is detected, the purifier automatically shuts off. Genius." — Rebecca Brown, former contributing editor
