Air Purifier reviews

HEPA H13 filtration in a unit that doubles as Dyson's signature bladeless fan. No app, no Wi-Fi, and only enough coverage for a small room. The fan-mode trick is the whole reason to consider it.

Strong CADR, the best app in the category, and a price that makes the bigger Coway look greedy. Loud at turbo, and Levoit quietly stopped calling the filter HEPA in 2023.

A genuine large-room purifier with smart sensors that actually work and an energy bill that doesn't. Overkill in a bedroom, perfect in an open floor plan.

An $800 purifier with one of the heaviest carbon loads on the market. It eats odors and VOCs the way a small purifier can't. The app is a joke and the box is enormous.

A slim, six-stage purifier that you can mount like a piece of art and customize for your specific household problem. The app is broken, the price is high, and there is genuinely nothing else like it.

A loud, simple, large-room workhorse with a Turbo button that earns its name during wildfire season. The running costs are real and the noise is louder.

A 360-square-foot purifier with a disable-able ionizer, a washable carbon filter, and the best value in the category. Discontinued in 2025; replacement filters run until 2032.

A nine-hundred-dollar German-built purifier with a ten-year warranty, five pounds of carbon, and zero ionizer. Overkill for clean air; correct for asthma, smoke regions, or anyone done with compromise.

A PECO-and-HEPA hybrid that chemically destroys pollutants instead of trapping them, with an FDA medical-device clearance to back it up. The filters cost more than some purifiers.

Strong, quiet, simple, and wrapped in a swappable fabric sock that actually looks nice in a living room. The catch is buried in the spec sheet: the ionizer is always on, and that's why it loses points.

A mid-size HEPA purifier that clears a real room without sounding like a hair dryer. The app is forgettable, the filters are cheap, and it just runs.

A 930-square-foot HEPA purifier with a real-time air quality sensor and a quiet fan that doesn't drone. About $450, and it earns the corner it sits in.
