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

About the quality of "air washing". There is no air washing. Designed for 40 sq. M. Stands in a room of 12 sq. M. There is absolutely no difference in dust settling on the surface with and without washing. The maximum that it can do is in a small amount of dust within a radius of half a meter or a meter from itself. Already after the purchase and bewilderment from the lack of air washing, I saw in the "Miracle of Technology" program on NTV testing all kinds of air cleaning devices, and so an air washer with a similar design also practically did not clean anything. About air humidification. Humidification is ineffective. The main parameter of a humidifier is how many ml of water it can evaporate in 1 hour. Examples about what relative humidity was and became after using the humidifier are incorrect, since the achievement of this humidity depends on a huge number of parameters, such as humidity in other rooms, and how often the door to these other rooms is opened, how often and how long you ventilate, and what is the temperature and humidity of the air at that moment on the street, how hard the heating radiators work, etc. It evaporates water naturally, which means that the rate of evaporation depends on the air temperature in the room. At a temperature of 22-23 degrees recommended by sanitary standards, the evaporation rate is approximately as follows: 1 speed - 130ml/hour 2 speed - 170ml/hour 3 speed - 250ml/hour Humidity above 40% practically did not rise, after a minute of airing at -30, the humidity fell below 20% and rose to the level of 40% for 8-12 hours. As a result, VENTA went to the pantry, and I bought the cheapest ultrasonic Chinese humidifier with a humidification rate of 400 ml / hour for 1800. It does not wash the air, just like VENTA, but it humidifies much more efficiently, working quieter than VENTA even at its 1st speed. Sorry for the wasted money. I sold it on ebay for the same 10,000 that I bought - fortunately, they have risen in price. She crossed herself. Chinese works flawlessly.
