Can I hear the Air Protector One?

The noise level of the Air Protector One depends on the strength is has been set and can also be adjusted automatically. Since the noises of the fans at level 1-2 (25-35db) are barely audible, the air cleaner can run during normal working hours and in automatic mode. At maximum power level 4 (55db), the noises of the built-in blower are clearly audible, so we recommend these power levels for intensive air cleaning, e.g. during breaks or when no one is in the room. This way, it ensures a particularly low noise level.
