Have long wrestled with me if I so anschaffe me a great device. In the last two years I had a lot to do with dry eyes and our floor showed gaps caused by too dry wood. So clearly low humidity. I then first decided to use a nebulizer. But that was nothing. In the morning when you came into the living room was all white. The tiny water droplets had connected to the space dust and reflected on television, glass and all the furniture as a white film. Then bought the air washer from Venta. Unfortunately initially too small for our large living room of about 40 square meters. Although this product was at its height had not yet done a great deal for almost two weeks. Returned as a unit and ordered the large LW45. The it was then. Within a short time we had reached a humidity of about 50%. Since it runs on the lowest setting, and this ideal humidity holds now permanent. My eye irritation has declined and the joints in the floor have also become smaller again On the small stage, he is almost inaudible and interfere in any way. In addition, when you clean the container after a week, you can see only so correctly, which filtered out the dirt Venta air washer and has agesetzt in residual water. Overall, a very good buy.
