I have used many humidifiers. Don't like the ultrasonics. I just wanted something that would boil water and humidity my house in the winter. So easy to clean. Perfect. Please support AllergyBuyersClub. I love their recommendations and descriptions.
Having owned numerous Air-O-Swiss, Venta, and other humidifiers sold on this site over the years I am familiar with how these work. My main complaint about this one is that upon beginning to use, I noticed that the water container became slimy and smelly when it came time to refill, which is very frequently if you have it set at 50% and live in a dry climate. So, filling constantly, and them the slimy factor. I use filtered water from a Berkey, as I have done with all my other humidifiers and have never had this problem. Perhaps it has something to do with the opaque plastic rather than the transparent polycarbonate used in similar models. I purchased two of these. They are not as "quiet" as some of the reviews mentioned, but not horrible. The garbles of higher output setting will certainly bother you if you are a light sleeper.
