Bought because of an allergy to birch. They put it, the sensor showed 020 particles in the air, which is not enough. After 5 minutes it became 001. This is in Hong Kong at the corner of Rublyovka and Kutuzovsky, where the air is obviously terrible. I still have a question about the assessment :) but, after half an hour of operation of the unit, even with the window open, all allergy symptoms disappeared. So I don't care about the numbers on the screen anymore. Plus, after a week of work, there was no dust on the black furniture. So the thing works :)
