Review on Buy the Original White Venta LW25 Humidifier for Exceptional Air Quality by Siu ᠌

Bought Vent'u LW25 three days ago. I bought for a large room, but first I decided to test it in a small room. The area of ​​the room is 9 square meters. m, ceiling 2.5 m, initial humidity (before turning on the Vent) - 26%, air temperature in the room +22 degrees, outside -1 degrees. The results of the Vent's application are as follows: at the first speed (the lowest) it keeps the humidity 42-47%, at the second speed the humidity is 52-55%, at the third speed after two or three hours of operation the humidity rises to 58% (windows sweat) . Before going to bed, it turns on at the second or third speed for a couple of hours, then it works all night at the first speed. Quite loud noise at the second or third speed, but during the day it is quite acceptable. At the first speed, the noise is quiet, it is quite acceptable to sleep under such noise. I pour water once a day, in the evening. Water consumption 3-4 liters per day.
