- Cleans and disinfects. The display backlight turns off completely. At the minimum operating speed, the device is very quiet - it does not bother you at night. Once a week or two, when I leave home for a long time, you can turn on the sanitation mode and return after a couple of hours to an almost sterile (feels like) room.
- Writing about the price is trite. In my opinion, the price is justified, but you only know this when you stop using the device and again feel all the "charms" of the city air (although a breather is still installed in the apartment) - the difference is big. The backlight inside the device does not turn off. As far as I understand, it is she who participates in the technological cycle of air disinfection.
