Cleaner air,
without the guesswork.
We ran every major air purifier through the same particle, noise and filter-cost tests. Search 100 reviews or let us match you to one.
Real-room testing
Every unit, the same four ways
No sponsored rankings. Each purifier runs an identical protocol so the scores compare like for like.
Particle capture
We seed a sealed room with fine particulate and log the fall from 0.3µm up, minute by minute.
Noise floor
Sound is metered at 1m on every fan speed, from whisper sleep mode to full turbo.
Coverage & CADR
Clean-air delivery is mapped against room size so ratings reflect real spaces, not spec sheets.
Running cost
Filter price and lifespan are tracked to a true cost-per-year, not just the sticker.
