Rated 3.2 out of 5 by 33 reviewers.
Rated 5.0 out of 5.0 by Best one I've ever had I've had 5 different humidifiers over the past 8 years --- the ones with filters were an expensive pain to clean and the drugstore brands were noisy or minimally effective. This Holmes Ultrasonic is by far the best. I bought it at Sears in 2013; it lasted 3 years when it quit misting, although the motor would run. Couldn't find another one locally, so bought a Homedics which I returned the next day due to a high pitched whistling sound it made. Found my reliable Holmes online at their website and ordered it. Great customer service. It is relatively quiet as humidifiers go and makes a not unpleasant white noise type sound. The variable mist control is a plus. March 21, 2016
Rated 5.0 out of 5.0 by Easy Operation I bought this apx 6 weeks ago. The humidity level in my home is now very comfortable. Very easy to fill and maintain. It does seem to be noisy but after a couple days you get used to the sound. Overall this is a great product. February 28, 2016
Rated 3.0 out of 5.0 by Problem I bought this about a month ago and had a problem with it on the first day. I ran it for about 8 hours and turned it off when I went to bed. Next morning water was all over the place. It seems when turned off the cap would leak water into the unit and spill out. Called a told them my problem and they sent out another cap. So far it is working fine however I keep in in a pan just in case. February 12, 2016
Rated 4.0 out of 5.0 by No filters to change! Our first ultrasonic humidifier, and not our last. We have had the filter type humidifiers for years and are very pleased with the quietness and ease of operation of the ultrasonic unit. The only drawback so far is that the tank does not stand on its own when you are filling it. It can be quite cumbersome in the sink. February 13, 2016
Rated 1.0 out of 5.0 by Scam DO NOT BUY! Buyer be aware! The unit was working ok for little over a year until a small o-ring gasket inside the water tank to regulate water release has completely disintegrated and in need of replacement. The Holmes support indicates they don't sell the part and I need to buy a whole new unit! wow! February 11, 2016
Rated 5.0 out of 5.0 by Excellent features Excellent product bought last month and working great February 12, 2016
Rated 3.0 out of 5.0 by Good It's good but make a high pitched noise, almost like A white noise. February 10, 2016
Rated 4.0 out of 5.0 by Decent Humidifier/Better Customer Service The humidifier does its job. I had an issue where the container cracked within 30 days from the inside, but after a ten minute conversation with customer service I had a whole new humidifier delivered within 5 days. February 4, 2016
