After the first time I turned it on, I thought I'd return it right away. The dehumidifier made a terrible noise, respectively. something resonated inside him. After about 10 minutes of searching for a possible cause, I found that the sensor, or rather the "scale" with the magnet for detecting the maximum amount of water in the tank, was resonating. Just about 10 cm of el. tapes and the problem was solved. Otherwise, the dehumidifier does work, but don't expect it to collect moisture from larger rooms for its size. It's up to 20m2, I don't think it's more than that. If your windows get dewy overnight, for example. in the living room, that'll solve your problem, but I wouldn't put it in the daytime or in the bedroom at night.

After the modification, it is relatively quiet in the final

Surprisingly, it works - dehumidifies

price/performance ratio

Unfortunate "sensor" for water quantity - resonates

During the day the noise level is OK, but when the pump turns on, or whatever it is, it is quite audible

Very inaccurate humidity indicator

I'm reducing the humidity in a block of flats where it's normally around 60% over the winter. I always reduce it to about 50% at about 21-22 degrees and it will run at peak performance in about 2 hours. It has an automatic dehumidification function, but that doesn't mean it turns itself on when the humidity rises and off when it reaches the desired humidity. As soon as it drops 5% below the desired humidity, the dehumidification is switched off, but some kind of circulation continues, so it hums in the same way that you don't know whether it is still dehumidifying or just circulating. So it's not possible to leave it on all day at home with the expectation that it will do its job and then switch off. No, he'll go for three days straight, but only a few hours of it will really be a drag. I find this function nonsense, it doesn't have much to do with automatic dehumidification, so we have another humidity detector at home and we turn the dehumidifier on accordingly. The timer works though, it shuts itself off. The noise level is not very high, I have it a short distance from my bed and I can fall asleep with it.

design

silent

after starting the device, an unpleasant pungent plastic smell wafted from the device, which did not disappear even after 20 hours of operation. We took another brand and there was no similar problem, if anything, after the break-in within an hour nothing was felt.
