The H12 400HB 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.

Rated 3.4 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by good one for the price this is the second one we bought the first one lasted 15 yrs November 1, 2014
Rated 5.0 out of 5.0 by Works better than any of the other "whole house" humidifiers I've purchased over the years. Quiet, efficient, almost too good. Unlike every other "whole house" humidifier I've ever purchased, with the settings on low, my home stays comfortable. Even my cat appreciates the no-shock, no static level we now enjoy!

Rated 4.0 out of 5.0 by Humidifies Well. A bit noisey all night (tank fill noise) Product humidifies well. However, after you fill the plastic tank as recommended, the water slowly fills all night. In doing so, it goes "clunk" "clunk" "clunk" "clunk" every two minutes and is still keeping us up in the evening ...hoping we will just get used to it. I think the design is flawed in that they need to have a something to allow to breath after you flip it over and let it empty into the main resevoir..not sure. Besides that, we like it. June 10, 2014
Rated 3.0 out of 5.0 by Review of console humidifier To be fair, there can be no comparison between the quality of the humidifier I purchased twenty years ago and the one I have purchased recently to replace it. The general quality of the older appliance wins, hands down. Having said that, I will say that this product has the largest water reservoir of any that I could find on the market which is a plus. Still it must be refilled twice a day to maintain 30% humidity on the main level of my house (1350sqft), unlike the one I replaced which had a reservoir that was good for 3 days. One other negative is that the water container, which is quite heavy when full, has to be inverted and lifted into the device rather than filled in place and is quite difficult to "seat". Other than that it is not a bad machine. It looks good and is relatively quiet when run on low speed. February 6, 2015
Rated 5.0 out of 5.0 by Winter Helper This humidifier is way better than some of the smaller models I've seen in the stores. When the fan is on the low setting it is pretty quiet and still provides all the humidity I need to help out with dry air from our central air heater. February 4, 2015
Rated 4.0 out of 5.0 by Humidifier Product is great but shipping was bad, it was damaged , was scratched up looks bad but runs well April 21, 2015
Rated 3.0 out of 5.0 by Cheap but effective Overall, I have learned to live with the shortcomings of this unit. It uses very cheap materials. The plunger to electronics section is very difficult to line up when assembling. The water tank does not easily line up with the chassis that releases the water. The filter is done after less than 2 months of use. Other that that it does work, so far. January 13, 2015
Rated 4.0 out of 5.0 by It works! Can be a little bit loud on the upper fan levels but othewise it serves th purpose. August 26, 2014
