If you want maximum cleanliness, then buy this thing + humidifier (so that dust settles on the floor) + robot vacuum cleaner (to collect fallen dust every day) + vacuum cleaner with wet cleaning and aquafilter (so that it does not throw dust back into the air). This is my best solution to the dust problem so far. Some pros: It seems to clean the air. Responsive to pollution. Feels smoke, steam from the tobacco heating system (begins to make a lot of noise). Can be automated via the app to enable silent (night) mode at night. In addition, at high speeds, it mixes the air in the room (it is useful if it is calm on the street, and the air is stagnant in the apartment). Cons below: Don't count on it to get rid of the dust. This thing draws in air locally, only around itself. The robot vacuum cleaner regularly picks up a bunch of dust from the floor.
