Put an end to desert-like air in your home. The average humidity in the Sahara Desert is 25%. In wintertime, the average humidity inside some homes can be even lower, leading to dry skin, "carpet shock", cracking woodwork and more. Reliable Honeywell Whole House Humidifiers work with your home's heating and cooling system to maintain a proper, comfortable humidity level throughout the home. They will save you money by allowing you to turn down your thermostat a few degrees because humid air feels warmer. Plus, you don't have the hassle of refilling the unit like you do with portable humidifiers.

  • Good humidification; for all homes 2,000 sq. ft. or less
  • Easy installation
  • Water supply automatically refreshes daily

Rated 4.0 out of 5 by 30 reviewers.
Rated 3.0 out of 5.0 by Installed easily, but had to troublshoot noise issue Product works. Total install time was about 2.5 hours. I replaced the flexible hose with round sheet metal ductwork. Also, the required water line was already in place from an older humidifier install. Here's the catch: the humidifier produced a periodic "fog horn" like sound after the install. It took me a couple of weeks of rushing to the basement when the noise occurred to determine the cause. The cause? The plastic discs that hold the foam roller in place had to be pushed closer together than I intuitively thought (based on the directions). Somehow their was a friction-based noise that echoed throughout the house via the ductwork. December 30, 2014
Rated 4.0 out of 5.0 by Good unit. Installation requires some DIY skills Installation was actually pretty straight forward but there were a few "short comings" in the kit that I think people should be aware of. the supplied duct is just way too short. I have a "highboy" style air handler and the return and supply ducts are pretty much right next to each other. Only a few inches apart actually. I had some trouble getting the supplied duct to reach far enough. it's 3 feet I think but if you need to bend it 90 degrees you lose a foot of length. Measure first and see if you need a longer duct. save yourself a trip. Also, the duct has a block off plate that isn't really sized properly. IF you cut a full circle into the supply ( as the instructions indicate) the block off plate will only cover about 75% of the opening which is just way too much. Solution: Cut the hole smaller and in a somewhat oval shape. A bit more work but the shutter will then fully block the duct when it's not in use. The kit comes with a plastic water supply line ( PEX? ) So if your building code locally requires copper, you'll need a new line. Again save yourself a trip and get it while you are at the store. Finally, you will need a near by outlet and water pipe to tap into. If there is no outlet near your furnace, you'll need to have one put in. Finally, one of the little plastic bits on the drain was too big to fit properly in the unit and I had to use a dremel to file it down to size. Given all of this, I wouldn't take on this job like this unless you were pretty handy. I was able to get it done in a few hours. As for the function of the unit, it seems to be working well. Once I got all those little installation details worked out, everything works very well. No leaks or anything and it worked the first time I turned it on. The humidity level in the house is coming up nicely and it requires basically no work from here on in. November 15, 2012
Rated 5.0 out of 5.0 by HOUSE HUMIDIFIER We purchased this humidifire to replace a console unit that we purchased 5 years ago. It still worked well however I got tired of putting water in the console model. The installation and instructions was self explanatory. As this is new I can say that as of now it works well and I like where you can regulate the amount of humiidity you want in your place of residence. November 3, 2015
Rated 2.0 out of 5.0 by Parts were damaged in a sealed box The drum end had a manufacturing defect that did not allow for the motor to engage it. Honeywell Customer Service was worthless. The issue could not be found until the entire installation was complete, so I have to take it all apart to return it. There is no way to get just the piece that is needed. Check every component very closely before starting installation..... November 7, 2015
Rated 4.0 out of 5.0 by easy to install humidifier was easy to install every thing to install was in the box the instructions were good November 10, 2015
Rated 5.0 out of 5.0 by If replacing another drum unit, read this... This humdifier works great and has definitely made a difference in our home. Installation would have been fairly easy if this had been a new install but when replacing an older drum unit, it was all the small things that added up - stubborn fittings that wouldn't come loose on the old unit, and the duct work supplied with this unit not being long enough. I believe this unit comes with 4' of bypass duct, which was a tad too short so I had to run out and get an 8' piece. Once installed, the unit performs beautifully. January 18, 2010
Rated 5.0 out of 5.0 by Nice Humidifier design and operation I have had a "pass through" humidifier for years - have not had a drum one like this for a long time. But, my pass though kept leaking and I bought this one. Whomever engineered this product did a wonderful job. The instructions, parts, and assembly went very well. Everything worked as advertised........ January 4, 2009
Rated 5.0 out of 5.0 by Great humidifier Just like the instructions say: Each installation will be different and I had a few challenges, but just a little common sense and everything went together superbly. Our water line source is PVC (which isn't covered in the installation booklet) so I drilled an 1/8" in hole and secured the tap to it and it works great. Our air quality has improved from Sahara desert uncomfortable to a very nice humidity level that will make a huge difference on our dry itchy skin. Great little unit - highly recommended. We packed up our room unit humidifiers for the next garage sale. February 12, 2011
