Effectively relieve dry nose, throat lips and itchy skin with the virtually silent Dual Mist Humidifier with ION exchange filter. Will help you breathe easier and sleep more comfortably. This ultrasonic humidifier disperses warm or cool mist. A split nozzle for bi-directional mist for wider coverage. Sleek design with easy to use control knobs. Large, transparent blue water tank with easy-carrying handle. ION exchange filter demineralizes and treats water to reduce scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles to deposit into the air.

Rated 4.0 out of 5 by 9 reviewers.
Rated 3.0 out of 5.0 by Just OK The humidifier produces a good stream of mist, but probably not quite enough for the claimed 500 sqft. It was initially very quiet and I was delighted, but in just a few days of operation it became much louder with an annoying drone, almost enough to return it. The water tank is inconvenient to fill, and it is impossible to remove without dripping some water, but I could put up with that in return for its original very quiet operation. February 3, 2015
Rated 5.0 out of 5.0 by Excellent Humidifier. Worth the price. really pumps out plenty of humidity to our living area and bedroom. Just be careful on the high settings, it actually pumps out too much mist to be absorbed into the air. Leaves droplets on the floor 60-70%, is perfect. January 27, 2015
Rated 3.0 out of 5.0 by Some kinks We have only had the unit for 2 weeks. The nozzle that puts out mist was leaking when first started using it. Called company (maker of unit) and reported this. They quickly sent a new nozzle replacement to us which works without leaking. Very good mist output. Good size water reservoir but the cap where you fill unit with water is very difficult to open even if it is not over tightened. After the filled reservoir is placed back on the unit it has made an unusual sound after turned on, for a seconds. This has occurred about three times so far, which did not happen when we were initially running it. If it happens again will contact company for advice. Otherwise, it does run quietly.

Rated 5.0 out of 5.0 by Good investment The unit is very good in generating increased humidity in a room. January 28, 2015
Rated 5.0 out of 5.0 by finally, an versatile and easy to clean humidifier! After decades of exasperating attempts to make drug store humidifiers work for ordinary bedrooms (either too much or too little vapor), I am thrilled with this machine. It has a wide range of settings (at top level actually helped our entire house), allowing use in average bedroom without making everything damp. AND it is easy to clean. I recommend it without reservation. January 11, 2015
Rated 4.0 out of 5.0 by Works Bought this to replace the humidifier we had in the bedroom. It works better than the model we previously had. January 21, 2015
Rated 4.0 out of 5.0 by This product is quiet as well as effective. I am pleased with the ease of the setup of this product, as well as how quiet...practically silent it is. My apartment was extremely dry and causing sinus problems for me. After using this humidifier for only a week, I noticed the difference. Additionally, I like that this device has an auto-shut-off if the water level gets low during the night, or if I forget to switch it off when I leave the house. March 5, 2013
Rated 3.0 out of 5.0 by it is rather small in size- enough to use in a bedroom. I like the warm mist option. It is rather small in size only enough to use in a medium sized bedroom. I like the quiet quality of the humidifier. February 21, 2013
