Coway Airmega 150 review
A simple, cheap-to-run purifier for a bedroom or nursery.
Verdict
The cheapest to run on our list, with a genuine H13 filter. The colour ring shows air quality at a glance, without an app. Well built for the money.
Keep it to one room. Winix's budget models edge it in lab tests.

How it handles Perth's air
- Bushfire smoke: fair. Fine for a small closed bedroom; too small for anything bigger.
- Pollen: good in a bedroom with the door shut.
- Dust: good.
- Pets: good.
Watch out
Coverage is small, there's no app or scheduling, and Coway doesn't publish a CADR.
