Great humidifier at a great price!!

I am so very happy with this top notch humidifier. It has been mostly on solid since I received it with no problems at all. It is very quiet and produces a large amount of mist. As quick as my furnace dries out my place the humidifier puts back the moisture in my home so it is much more comfortable now. Thank-you walmart for directing my to this awsome product. It is exactly what I truly needed.

Nice to breathe moist air.

This really puts out the mist, even on low. It is very quiet and in my opinion it has only one dislike. If your electricity should go off for even just the least second, the machine shuts off. It does not turn itself on again. It's nice to know your power went off while you were out, or while you were asleep, but also during that time, your moist air was lost. My last machine lasted almost 4 years, 24/7 but it was not this brand, so I am hoping this one can do as well. I have used it only for moisture since we live in a very dry climate, and I think the plants like it too.

Excellent Humidifier for the Price.

Very easy to fill, quiet, puts out ample mist, and the timer is handy. It has a nice soft light which I don't use as it's close to my bed. The angle of the mist output can be changed which I found to very handy. I'm able to keep my room at a comfortable humidity level with this unit. Well worth the price.
