Filters generally indicate a CADR (Clean Air Delivery Rate in m3 / h). For example, a typical 3 x 3 x 2.8 m (approx. 25 m3) bedroom has 25,000 liters of air to clean. If you can now close windows and doors, CADR is not a problem, as it stays that way after cleaning until more “dirty air” enters the room.
Air purifiers either have a fan or simply let the air back into the room.
And then we look at the ongoing energy and maintenance costs.

First impression – EXCEED
The new series is a cylindrical water cooler compared to 2019 high plate.
These have a soft mode, sleep, auto and turbo.
CADR – PASS – only
- 800 – 190 m3 / h
- 2000i – 330 m3 / h
- 3000i – 400 m3 / h
The CADR sounds good, but is not as high as expected for the specified room size. Our calculations show that the room area needs 1.6 cleanings per hour.
The air purification series Philips 2020 fell victim to the theoretical figures. “From the air that flows through the filter; It’s a theoretical time for one-time cleaning charged by dividing the CADR 400 m3 / h by the room size of 48 m3 (assuming the room has a floor area of 20 m2 and a height of 2.4 m2).‚
We think one time is too low to compare to others using higher ratios.
Filterwirkungsgrad – PASS

- 800 – 99,5 / 99%
- 2000i – 99,97 / 99,9%
- 3000i – Like 2000i and has a volatile gas sensor
Airflow – PASS
Air exits in a spiral upwards. It is not a fan unit.
Sound – PASS
Philips cites dBA (weighted) around 35-65dBA. For real numbers, add around 20-30%. These are within typical limits.
