Review on Smart & Clean HealthAir UV-03 Air Purifier, white by Mateusz Walkowski ᠌

When you first turn it on, it immediately works with a malfunction. Checked in several rooms. There was no strong dust in the rooms, it was clean. First, within a minute "determines the level of PM 2.5", the indication is green, the speed is first 2 then 1, the value of the PM 2.5 parameter gradually decreases from about 80 to 10-12. After about 30-60 seconds, it starts flashing red, "H" appears in the value of PM 2.5. Nothing about this value in the instructions is not said. The instructions from the "similar" Kitfort 2812 air purifier indicate what the "H" value means: "At medium air pollution, the device indication will change to yellow/orange, with very strong air pollution - to red. At the same time, if the air pollution level exceeds 300 µg/m3, then it is dangerous to be in the room without appropriate respiratory protection. The touch panel will display the value "H" and the indicator will flash red. Leave the room or put on a mask." The rooms are clean, the minimum level of PM 2.5 content is initially shown, but then the "critical excess" of the level is sharply determined. The purifier is not working properly.
