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
  • Floor drain required

Rated 4.3 out of 5 by 20 reviewers.
Rated 4 out of 5 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 4 out of 5 by works great The humidifier assembly and install was the easy part, the wiring schematic is carp. It shows extra connection points for no reason. It could easily be simplified to terminate red and white wires on transformer, take white to humidistat, take other leg of humidistat to motor, connect red wire to motor, done, complete circuit. Plug in transformer. If you are installing the humidistat upstairs its a longer run. Next would be measure and verify where you want to install it. My highboy required two elbows and a four foot section of pipe, not that flexi garbage. Feel free to buy machine screws as well unless you like drilling pilots, also 1/2" are plenty long.

Rated 5 out of 5 by long install, but worth it Good instructions and al lparts were included. Takes a while, but you can do it in steps. Humidity went up as expected after one night. December 10, 2013
Rated 5 out of 5 by Great product I have a few old guitars that need a controlled humidity environment. My two story townhouse is around 1700 square foot. This humidifier did the trick. It took my house from 35% to nearly 50% overnight. I have also noticed that I did not wake up with a dry throat or nasal congestion so I am a very happy camper. It took a couple of hours to install but if you can operate tin snips and do basic wiring, you should not have any issues. Everything I needed was included in the box and the three foot length of 6 inch vent hose was just enough for my application. The unit came with a control assembly so I believe it shuts off the motor after reaching the dialed in humidity level. Overall, it's a pretty basic design that works great. January 6, 2014
Rated 5 out of 5 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
