The H12 300HB offers convenient whole house coverage in a single bottle design. It adds invisible moisture to your home by moving dry air through a saturated wick. Maintaining proper humidity levels between 30-50% in your home/office/workplace has been scientifically proven to help prevent the flu and allergies. It reduces static electricity, relieves dry skin and scratchy throat, and protects fine furniture and wood floors. Proper humidity makes you feel warmer allowing you to lower your thermostat setting which will save money.

Rated 3.3 out of 5 by 11 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 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
Rated 3.0 out of 5.0��by ideal for the hard of hearing This unit replaced a console humidifier we had used for nearly 20 years. First thing I noticed was how thin the plastic housing was. It feels flimsy and fragile. I did like the single large wick, it fits well and the design makes sense. The single water tank is not large, so if you plan on treating a large area, plan on refilling 2 or 3 times per day. Also, several times the tank did not drain into the console refilling, and the unit stopped, display read it needed filling (F) and the tank was full. Customer service sent a replacement part and a pvc shim to help line things up. Works better now. The fan (which has 4 speed settings) was initially quiet, but in the course of a couple of weeks it went from quiet to very noisy. It rattles like crazy! This thing makes so much noise that we keep the door closed in the rooms we are using. I've checked and tightened all the visible screws, but it made no difference. The humidity level in the house is well maintained using this unit. If you don't mind the noise, buy with confidence. January 7, 2014
Rated 4.0 out of 5.0 by Very satisfied We've had the unit in service for a week. When we started it running the humidity in the house was 25%. In the last week it has fluctuated between 36-42%. (We have it set on 40, running the fan at the lowest speed.) Two downsides are that the fan is fairly loud at higher speeds (but we discovered we don't need to use those speeds), and, as another reviewer noted, the refill tank can be a bit tricky to set in place so that it drains properly. Being careful in putting it in the unit is necessary to insure the valve is properly seated to work properly. We are, however, quite pleased with our purchase. It is working very well. Within a couple of hours of turning it on we noted the house felt warmer. My wife's hands, which crack badly every winter due to dryness (even w/lotions), are much better this week, with no cracking. Throughout the week I have been wearing fewer layer of clothing around the house, without changing the thermostat setting. The controls are easy to use. The refill hose makes refilling the tank simple. We are operating the unit (which is rated for up to 2500 sq. ft.) in a home of about 1400 sq. ft. December 21, 2013
Rated 3.0 out of 5.0 by It works well, but is loud on the higher fan settings Worth the price but it is a little loud on the higher fan settings January 7, 2014
