Rated 4.0 out of 5.0 by Paul Simple, Foolproof Humidifier
I've had this humidifier installed for about a month (December) of heating season, and it seems to be performing well in my environment. I live in a 1,900 sq. ft. 80 year old house, which is not tight, located in Michigan's Upper Peninsula.
The installation was an all day affair, mostly not because of the humidifier itself, but the existing furnace and ductwork. The ductwork is older and seems to be heavier gauge, and very difficult to cut with snips. In a prior house I had used a sabre saw to make cuts for a humidifier. In addition, it was tight maneuvering no matter what cutting tool one is using. So be prepared to spend much more time than the rosy picture painted in the description.
Another difficulty with the install was the bypass duct supplied will be too short for many (most?) installations. It is supposed to be 36" long, and I managed to stretch it to 35", but it was a major job trying to get it connected at both ends. It got pretty mangled in the process. I ended up ordering an 8 ft. piece of semi-rigid 6" duct and replacing the piece that came with the humidifier. Just order the longer duct when you order the humidifier and save yourself a ton of frustration.
This humidifier is not completely quiet, and the drum turns whenever humidification is required, not just when the furnace is running. You can't hear it when the furnace is running, but you can when the furnace is off, depending on ambient noise in your house. A minor issue that may annoy some.
The humidistat and its recommended settings may not be the most accurate, so get a humidity meter if you don't already have one and double check your settings. You can then adjust the humidistat setting based on what you are actually experiencing.
One of the things I like about this humidifier is its absolute simplicity, with seemingly nothing that could or should go wrong. The replacement pads can be gotten dirt cheap in quantity. And it fit my ductwork, which many humidifiers don't fit.

Rated 3.0 out of 5.0 by Rich 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.

Rated 2.0 out of 5.0 by Fred lasted 7 1/2 years, but didn't add a lot of Humidity
I got this installed in my home 7 1/2 years ago. Now the motor has went out and I need a new one. I didn't have a humidifier at first so after it was installed, I was able to tell a slight difference. However, I had to go to Walmart and buy humidifiers for each of my three bedrooms because it didn't put out enough. Also, I don't know if I just have hard water or if the little bit of metal on the parts are causing it, but each year I have an extremely large amount of white corrosion build up inside of it, and have to take it apart to clean it, and change the filter. I wont be buying another one.

Rated 1.0 out of 5.0 by Ken Waste of money
First you have to install it. Which I wouldn't mind if it worked. It's roughly 2 hours of labor to do it yourself. I have had this product about a year and it does absolutely nothing. Don't waste your money you will be buying a new one to replace it. The plug in model that you fill with water did 10x better job then this. I was hoping that the whole house model would save time not having to fill water jugs all the time. But the system can't get the humidity of 20% unlike the plug in models that could raise it to 50% in a few days. I wouldn't recommend buying this

The unit was missing the clips to hold the drum to the shaft, also the drain hose clamps were to large for the drain tube, sent Honeywell an email and they told me to go buy a replacement drum. I did that along with smaller clamps for the drain hose. Will not purchase any products from Honeywell again.

Rated 4.0 out of 5.0 by Nate Pretty good!
2 winters so far. First winter installed w/out in-line water filter on hot supply line: water reservoir and drum pad didn't make it til Spring. Ugly plumbing situation combined w/Chicago water left unit caked with hard water buildup, deposits and smelled musty. Second winter with in-line 5 year fridge water filter on cold supply line: the difference in adding a supply line filter is unreal. Water in pan is crystal clear, no funky smells and humidity is a steady 47% in a 2500 sqft home of 3 levels. Pan is perfectly clean and the drum pad won't need replacing next winter thanks to this:
Don't let negative reviews turn you away from this unit. I'm sure it's no-joke frustrating to install if you're not handy.

Rated 4.0 out of 5.0 by Louis 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.

Rated 5.0 out of 5.0 by David Good Humidifier and easy to install
Replaced a flow thru type that only kept the house at 25%. This was an easy replacement - was able to use old duct work and electrical. Drum type is now keeping the house at 46% easy. Since the water tray comes out it will be easy to clean and maintain. Very quiet operation and uses much less water. Old one used about 50 gallons a day. This one uses only what gets evaporated to house. Pad can be cleaned or replaced once a year.
