How to choose air purifiers
Match clean-air delivery to the room
Look for a stated CADR and the room size used to calculate it. A purifier should cycle room air several times per hour for meaningful results.
Filter stages
A particle filter captures airborne particles; activated carbon targets some gases and odours. Check replacement intervals and genuine filter cost.
Noise and sensors
Automatic modes depend on sensor quality. For bedrooms, compare low-speed noise and display dimming as well as maximum performance.
Check before ordering
Check current compatibility, dimensions, specification and warranty, and confirm the included accessories.
