I use this in my bedroom and it really keeps the air clean, and is so quiet, you don't even know it's on. Since I don't drive, I gave the one for the car to my grandson. It is a really good buy.
This is by far the best humidifier I have ever purchased. It works well and blows out a very strong stream of cool vapor. The design is nice. It doesn't have that "medical" look that other humidifiers have *** . I've only owned this unit for a week, so as far as build up of lime, or whatever hard water has, I cannot comment. Highly recommend.
