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.
The test the CADR comes from. AHAM AC-1 and the DOE test are independent and comparable. A maker's own test is not.
The CADR measured with tobacco smoke, the finest of the three test particles. It is the figure to read for wildfire smoke.
The CADR measured with dust.
The CADR measured with pollen.
The CADR measured for particles under 2.5 microns.
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.
How many times an hour the maker assumes the air is changed when it states a room size.
A filter of activated carbon that takes out smells and some gases. It does not catch particles.
The sound level at the lowest speed, as the maker measures it.
The sound level at the highest speed, as the maker measures it.
The power the purifier draws at its highest speed.
Air delivered for each watt, the ENERGY STAR measure. Higher is better.

The fan speed follows the air quality the sensor reads.
What the purifier weighs. It counts most if you move it from room to room.

The ozone the purifier gives off, in parts per billion. California allows at most 50.
The CADR is verified by AHAM, the US trade body that runs the test.
The warranty the maker gives in the Netherlands. Consumer law here stands apart from it and can last longer.
