Have long tried me on the Internet to make smart about humidifiers and / or cleaners. Difficult because opinions diverge yet far. Then I made my own thoughts and I ended up with this one. Why, even a great visual for me with no frills and very quiet. It goes on, technically I find here to use solution brought very good and practical. The humidifier consists of two parts, water tank bottom and top fan. Simply remove water fill finish. Approximately 1.5 l is not much but it is enough, so the inflow of fresh water is naturally guaranteed, what prevents the nucleation. Phillips has but vorgesort and also built a small "cleaning cube", very good, you can buy more. The actual evaporation takes place over a large paper filter and which in turn is supported by a very quiet fan. The paper filter has two clever functions for a he transported the water by capillary action on its entire wide area and acts partly as an air filter. The filter can and should clean weekly with clear water. Furthermore descaling is called for, depending on infestation with normal vinegar solution. The regulation of humidity takes place automatically on request. Finally now the power, in room size of 25 sqm and a ceiling height of approximately 3.65 m to reach a constant humidity of 50% for fully automatic operation of approximately 12 h p. Day. I would buy the product again, because it has convinced me in practice.
