Cool Mist

In my opinion, this is an adequate humidifier. No, it is not a "silent" machine, but it efficiently does its job. (I personally like the "white noise".)It is very reasonably priced. Major drawback that I found - difficult to maintain - the cleaning ritual must be rigourously adhered to, otherwise, the filter will get moldy. I live in So. California, where it is quite dusty. This results in a lot of particulate matter getting trapped in the filter, which, in the end, is part of what you want it to do. I find the filter-changing to be more of a nuisance than I'd like. (I have purchased these online separately from Kaz.) The design of this humidifier is a little lacking - the plastic tends to crack easily, and you have to work to get the filter to sit properly in the housing. Since this is the first humidifier I've owned, I can only state what my experience has been - it may be that all cool mist humidifiers have to be pampered.
