I was fed up with constantly filling portable humidifiers and cleaning up all the mineral deposits so I bought this. Install was straighforward but time consuming. Bottom line: this will easily humidify a large house and the only maintenance is changing the filter each year. The filter traps all the minerals or they wash down the drain and there is virtually no cleanup. So much nicer than scrubbing caked on deposits with vinegar in my portable unit. Be prepared for a bigger water bill. When running it wastes a lot of water, but I figured I offset the higher water bill with a smaller heating bill because you feel warmer with more humidity and we were able to reduce the inside temp 2 degrees.

I installed the unit using hot water to speed up humidification. The outer vent in the photo is just to cool the blower motor and is separated from the air duct by an internal barrier. After installation, a loud whistling noise occured even when it was powered off. Seems that there are several small round holes in the barrier that once upon a time were used to mount something. Once they were plugged, it ran quietly. Aprilaire really needs to remove these holes.
Its built in fan drives air thru a honeycomb block that has alot of wet surface area. Water went in hot (120F) but came out (10F) colder than the room air. House humidity jumped 10% in a few hours and then stopped rising. It took nearly two weeks of continuous operation before the humidity rose again. I think that wood, carpets and fabrics must have been absorbing most of the moisture that it was producing. Now it runs an hour or two a day to maintain the set point.
The electronic control has a remote outdoor air temperature sensor that changes the units set point to prevent condensation on cold windows or glass doors. So if you want that feature a little more effort is needed to run the wire outdoors. The control works well and looks good.
The unit has been running for 3-months now and I am happy with its operation.

We purchased the 700 in 2004 and it has been nothing but a headache for us. The first two years the water panel wouldn't stay wet. The installer blamed it on the saddle attachement to the water pipe. He came out and cleaned the saddle and claimed it worked but we never had anything but dry air. About 2007 we had someone come out and tell us the panel holder doesn't distribute the water well and they came out with a new version that has fabric in it. Bought that and it helped for a year and the fabric came loose and had to buy another. (in addition to replacing the panel each season). Finally last year we had someone install a real valve to replace the saddle. Then this unit started pouring water all over the floor. Apparently the low-flowing saddle was masking other problems. Some low-flow, inlined device was broken. (read $.01 piece of plastic) I ordered a new hose for it and put it in. The new hose was so stiff that part of it broke on trying to install it. Duct tape helped hold it in place. Turn on the water and NOTHING... back to no water again and a dry panel = dry house. Generally this unit has me running to the furnace room every day since we owned it. It has never worked right despite having 3 different companies come out to service it. The general features of this thing that I don't like are:
- water panel: I just don't believe that this puts as much water in the air as one could
- fan: The fan is outside of the duct work blowing unconditioned air into the duct which is supposed to deliver humid air to the system. But I feel more air coming out than going in and isn't it reducing the heat in the duct by inserting cold basement air?
- vent: The vent on this thing is a giant hole in the summer. The unit is off in the summer and the cold air just blows out. One may suggest that I leave this thing on all year and just turn off the water... that would help but the way these are wired is to turn on only when heat is asked for. We keep our house fan on all the time to balance the system and the 700 only comes on when heat is generated. So even in the winter, conditioned air is escaping through this unit.
- water delivery: The pipe it goes through is entirely proned for error and anyone with harder water than us will suffer tremendously.
This is probably the worst house purchase we have made since 1998.
