  • Woks great for us.

    This humidifier has three settings. I didn't realize that when I made the purchase, so it was a pleasant surprise. I have ran it non-stop since we received the package. It works well and has increased the humidity as needed. I made the purchase to achieve the ideal humidity level for my husband's guitars. The light is helpful if you need a night light. We haven't used it other than to turn it on to see how it looks.

  • A Must Have for this Winter

    I feel like I found the Holy Grail of humidifiers. After so many trials and errors with different humidifiers, this is a keeper. I run it on high so I need to fill it more often but not a problem because it is so easy to fill and use. I don't have the sinus dryness now that I am using the heater and my skin is not dry. I bought it for health reasons, but I'm also getting beauty benefits as well.

  • Excellent Humidifier

    I would definitely recommend, it made a real difference. I bought 3 of these. One for each of my kids bedrooms and it made a huge difference. No more dry noses and throats.

  • Easy to use

    My triplets room needed a humidifier. I love how easy it is to fill and operate. My three year olds know how to operate it. They turn on the light. The soothing blue light is their night light. Watching the water dance in the tube lulls them to sleep. Glad I purchased this.
