Buying guide

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.

Common questions

How do I choose air purifiers?

Start with your main use, compatibility and the specifications that affect everyday ownership.

Is the most expensive model always best?

No. Choose the model that fits your routine without paying for features you will not use.

How current are the details?

Product details and availability can change. Confirm them with the retailer before buying.
