I bought it in the fall before frost, in 2022. It was very noisy in my opinion. Noisy air flow passing through the design of the humidifier. Over time, some gears began to crackle. I took it apart - there is a motor with a built-in gearbox and a gear hung on it that rotates the drum. In this gearbox, the gears crackle - that's why I often turn off the device at night. At the same time I checked the cooler. By itself, it works almost silently, but as soon as it is inserted into the case, the noise becomes very noticeable. The device humidified in the beginning very well. The hygrometer available in the house clearly showed an increase in humidity (35-40% all winter). And it didn’t feel dry, clothes, blankets, etc. didn’t beat with static electricity. The nose does not dry out - the sensations are normal. In March 2022, I noticed that half of the disks stuck together. Maybe the water was too warm. However, the ability to humidify has noticeably fallen - during the day I always leave it at the maximum fan speed. Due to the abundance of textiles in the apartment and the presence of a cat in the apartment, it is very dusty. However, the device seems to pick up almost none of this. Some dust remains on the top grate. However, I only change the water (every 1-3 days) - it can become a little cloudy. But it doesn't stink. In a bucket, a solid sediment such as scale is washed off with a brush. But not from the drums - they are non-separable.
