AirPure 300 Review: A Genuinely Quiet Purifier for Medium Rooms
The one we'd point most people to first — quiet, efficient, and cheap to keep running.
Check price on Amazon →What we liked
- Genuinely quiet on the lower two fan speeds
- True HEPA filter rated for rooms up to ~35m²
- Replacement filters are cheap and easy to find
- Simple controls — no app needed to use it well
What we didn't
- Top fan speed is loud enough that you'll only use it when you're out
- No air-quality display on the base model
We ran the AirPure 300 as a daily driver in a 28m² living room for three weeks, on the middle fan speed during the day and the lowest overnight. The short version: for most people in a normal-sized room, this is the one to get.
Does it actually clean the air?
On the middle speed it cleared visible cooking haze from the room in well under ten minutes, and the carbon layer took the smell with it — not masked, gone. A true-HEPA unit at this size is doing real work on fine particulates, and the AirPure 300 didn't struggle in a room a fair bit bigger than its rating.
Living with it
The thing that separates a purifier you keep running from one you switch off is noise, and this is where the 300 earns its score. The lowest setting is a soft wash of sound you forget within a minute. The middle setting is fine for a room with a TV on. The top setting is loud — useful for clearing a room quickly while you're out, not something you'll sit next to.
Running costs
Filters are the hidden cost of any purifier, and the 300's are cheap and widely stocked — you're not locked into a pricey proprietary cartridge. Budget for a replacement roughly twice a year with normal use.
