Rated 1.9 out of 5 by 35 reviewers.
Rated 4.0 out of 5.0 by Works just fine I have had several of these, & use two of them in a large room with a valuable grand piano and a high-output wood stove. They DO raise the humidity meaningfully. Yes, you have to clean the wicks in hot water and dish soap now & then; if you don't, the output drops. Read the instruction book. To the buyers who complain that they are filling it twice a day, but it's not working, I say: just where do you think all that water is going? January 8, 2015
Rated 1.0 out of 5.0 by Worst humidifier I have ever had The fan no longer works and I haven't even had it a year. It gives off a very little humidity and is basically a piece of junk. This was a replacement for the first one that didn't work. How many times do you replace it until one finally gets one that will work. How do I get a refund on this? January 8, 2015
Rated 1.0 out of 5.0 by cool mist tower humidifier Very poor product. Constantly clogs up. Filters are overpriced and only last a short time. Does not maintain humidity in a small bedroom. Overpriced for the lack of quality and poor performance. Would not ever buy this product again December 14, 2013
Rated 1.0 out of 5.0 by Poor Product The humidifier was ordered online and delivered UPS. The box was pretty beat up and had holes in it. The product did not work well at all. It never increased over 45% humidity in the room we used it (bedroom). So, I wouldn't recommend this product at all. March 3, 2015
Rated 2.0 out of 5.0 by Bion-who? Never heard of the name brand and the selection at HD was very very poor. (This was pretty much one of two to choose from I decided to give it a try. ) Although I did like the digital display on the percent of humidity level in room, it was why I eventually returned it to HD for a complete refund. The display would never read a humidity level above the 25-35% range. I even moved and tested it in smaller areas/rooms. It did not work or improve. I eventually purchased a Honeywell brand unit and have had success. February 3, 2015
Rated 4.0 out of 5.0 by good unit trick to using this is making sure wick doesn't go dry. If you use it to try to do a large area, use the timer at 5-6 hrs in the coldest winter. I love it !! January 10, 2015
Rated 2.0 out of 5.0 by Worst Humidifer Ever I wanted to love it this since the tower look is very sleek and I have been searching for a humidifier for months. But the fan started making clicking sounds a week after I got it. Very very noisy and the filters only lasted two weeks. The humidity never went above 25 and just blew lukewarm air into the room. Water tank is very awkward to use. Don't waste your money on this one. November 20, 2014
Rated 2.0 out of 5.0 by Reconsider other humiifiers Not worth the price. After a few days, fan becomes very noisey and makes clicking sound. Thought I had a bad one , returned it and the second one does the same! Must refill constantly. Has a very nice design and look to it but worthless. September 30, 2012
