Cleaning performance 3 facts
- Clean air delivery rate (CADR)
How much clean air the purifier delivers an hour, measured with smoke, dust and pollen. A higher figure cleans a bigger room or the same room faster.
- 350 m³/h
- Room size we compare on
The room size where the purifier changes the air 4.8 times an hour under a 2.5 m ceiling, worked out from its CADR. We use it so every model is compared on the same rule.

The room size the maker states. Makers use different rules, so we show it but never rank on it.
- 70 m²
