- really cleans the air.
- even at the first speed the fan is so noisy that I personally can't sleep. that is, it makes a quiet noise, probably within the promised 25 dB, but it will still be difficult to fall asleep under it in a room of 12 square meters. but I have a very fine ear. After a year, another drawback was revealed: the device has "protection against working with an empty bucket." So, we have hard water, and apparently the salts now open this contact all the time, even when the bucket is full. As a result - the device cannot be turned on, it does not work - it shows that the bucket is empty. Terribly disappointed. The main thing is that the guarantee may not accept this thing, they will say that it was necessary to use an additive to soften the water. But firstly, I sometimes added citric acid there to soften the water, it did not help. And I don’t want to add chemistry, because we breathe this as a result.
