Rated 3.1 out of 5 by 14 reviewers.
Rated 3.0 out of 5.0 by The product does not live up to its description on the website. The website description includes "Quiet night mode" but in reality it is just the lowest fan speed setting which is not quiet and reduces the output allowing overnight humidity to drop. Its bottle is much too small and requires at least three fillings per day just to maintain 40% in our 2400 square feet home during the heating periods. Disappointed but will keep it. Have to have one running for health. December 31, 2013
Rated 4.0 out of 5.0 by given as gift Gave this to my brother as Christmas Gift. He uses a wood stove to heat his house in NH. He did say it is not convenient to fill it. Also did say it works great. Not too sturdy though so you have to be careful not to bump into anything when wheeling it to sink to refill with hose. I will say I am not sure what he thought they would be made out of !! Plastic is what they all are made from. January 5, 2016
Rated 3.0 out of 5.0 by Home humidifier The humidier was purchased to replace one that we had used for many years. The materials in the new one are much cheaper then the old one. It seems to work well but time will tell if it holds up like the old one did. December 15, 2015
Rated 1.0 out of 5.0 by Not so great! The first unit failed within two months of use. The fan motor on the low setting would not come up to speed and just make a loud humming noise. If you changed the speed to a higher setting it appeared to function ok. The problem with that was, I did not need to run it any higher than low. I returned the unit, which went well, and now the second unit is doing the same thing, just not as often as the first unit did. I have not returned the second unit yet, but will if the problem persists and/or worsens. June 2, 2015
Rated 5.0 out of 5.0 by Works very well This unit works great brought our humidity level up on the first day and maintains it The high speed is a bit loud but during the day time hours you don't notice it and just drop the speed at night works great I'm very glad we purchased it March 31, 2015
Rated 5.0 out of 5.0 by Excellent Unit Of course something plumbed so you don't have to add water would be better but at this price very impressive. It works very well in maintaining nice humidity levels. No more static shock! March 24, 2015
Rated 2.0 out of 5.0 by Sorry I Bought it! One of the worst purchases I ever made. The unit is loud and disruptive. Uses more water than any humidifier I have ever seen. Not pleasurable to continually refill.. Don't plan on sleeping with the unit on any higher fan speeds. A complete waste of money - get something else. February 14, 2015
Rated 1.0 out of 5.0 by what a joke If you want to spend all your time adjusting the tank This is the tool for you. Its noise level is loud enough to drown out a naggin spouse. What a waste of money October 10, 2014
