How We Test Air Purifiers

CADR Rating

Clean Air Delivery Rate measures actual air cleaning speed in m³/hour. Higher is better. We recommend minimum 300 CADR for living rooms.

Noise Level

Measured in decibels (dB). Under 30dB is whisper-quiet for bedrooms. Under 45dB is acceptable for living spaces.

Energy Costs

Annual running costs based on 8 hours/day use at UK electricity rates (34p/kWh). Lower wattage = lower bills.

Filter Costs

Annual replacement filter costs vary from £30-£100+. Factor this into total ownership cost.
