Rated 3.8 out of 5 by 4 reviewers.
Rated 1 out of 5 by Failed to work after day one. Humidifier arrived in great condition and shipping was fast. However, it failed to atomize water after being operated for only one day. It was never run dry, it simply wouldn't mist the water after I filled it the second time. Capacity is more like 1.8 gallons, not 2.8 as advertised. I called the manufacturer to have the unit replaced under warranty, and was told that they were out of stock and I should try to return it to my local Home Depot. Local Home Depot gladly accepted my return and credited my account. March 3, 2013
Rated 5 out of 5 by Silent and easy setup humidifier for bedroom I replaced a Honeywell fan model with the Holmes Utrasonic. It is much quieter, there is a gentle whisper when it operates, if quiet is what you are looking for this is an option. Setup and operation are very simple. The one disadvantage is that the reservoir has to be removed and turned upside down to fill from the bottom. It can be messy and awkward since there is no real grip on the bottom. If you do not have a tub or faucet with large clearance below filling the reservoir will be awkward. Probably not suitable for elderly. All in all a good product with one design flaw.

Rated 5 out of 5 by Great Product. I have owned this humidifier for several years and it works great in my living room area. February 11, 2013
Rated 4 out of 5 by Works as advertised Easy to operate and fill. Works all night on about half a reservoir of water. Only draw back is draining it each morning and cleaning it every week. This is necessary though and is part of the discipline. I do recommend the product. November 12, 2013
