I use it for 4 days, it seems to work well but noisy: Level 1 is slightly less noisy that a fan. Level 2 and 3 are unbearable. leaflet recommends leaving lit permance, but try to sleep with this noise, even with the level 1. This is not possible for me. Another disadvantages of size: -the price of the filter which must be changed at least once every 3 months -The machine brews the cold air, you have to thoroughly cover interest you!
