Air Purifiers Reviews
Air purifier claims are notoriously difficult to verify independently. CADR (Clean Air Delivery Rate) figures are measured in controlled laboratory conditions that may not reflect performance in a furnished UK living room. We measure particle reduction in a standardised test space and assess filter replacement costs — often the largest long-term expense.
Ratings reflect editorial confidence and evidence quality. Read our review methodology for full details.

How We Review
We introduce a standardised quantity of smoke particles into a 25m² test room and measure PM2.5 reduction at 30 and 60 minutes. We also measure sound levels at 1m in each mode and calculate the annual cost of filter replacement.

Do air purifiers actually work?
Yes, HEPA-filtered air purifiers effectively reduce airborne particles including allergens and smoke. Performance varies by room size, fan speed, and filter quality. Our reviews measure real-world particle reduction.
How often do I need to replace the filter?
Replacement intervals range from 6 to 18 months depending on usage and air quality. We calculate the annual filter cost in each review so you can compare total cost of ownership.
