“The Aprilaire humidifier works great and was also recommended to me to help get rid of a static electricity problem in my house which also was very successful.”
“** 2 year update:I still love this humidifier it has never caused me issues that required replacement parts. The only maintenance i've done is changing pads every 6 months to a year and wipe down the inside with vinegar water to clean it up. Also twice the small orfice clogged causing water to slow or stop and humidity to drop. Easy fix with a small wrench and needle.**Original review:First of all, this humidifier is a lifesaver. It works amazingly well. But I'm reviewing because I want to help buyers who have a Carrier thermostat and furnace. My Carrier Infinity Touch thermostat did not use all the standard wires that most thermostats use. The wiring instructions for this unit did not apply to my system at all unfortunately because my Carrier thermostat was wired up with just 4 wires: +power, -power, data+, and data-. At first I thought the install wouldn't be possible because of the wiring but then I realized that my furnace computer board had a "hum" pin on it. In my case, the output was 24v AC, which is exactly what the Aprilaire unit was expecting in order to trigger the relay to activate humidification. So What I did was plug the two loose wires from the humidifier directly to "Hum" and the "C" terminal on the furnace. WARNING: Not all furnace "hum" terminals are 24v AC, so you need to make sure your unit has the correct voltage on that pin before doing that. Because the wiring was this way, my thermostat had to directly control the humidifier, so i did not use the aprilaire humidistat that comes with it. The most trouble in the whole install that I faced was that initially, my Carrier Infinity Touch thermostat would not allow me to control the humidity. At first, all the humidity settings were greyed out so I couldn't click them. If this happens to you, you need to enable the humidifier "accessory" on the thermostat. This is how: Go to the main menu on your thermostat (dont try this on the phone app), then click and hold the "service" button until it turns green (about 10-15sec). Then you should see a hidden menu that the technicians are supposed to use. From there, go to "setup" then scroll and click "accessories". Then click "humidifier". Now you can tell the system that you have a humidifier plugged in. You can also set a reminder for 6 months or a year or whatever to change your humidifier filter. The other option "humidifier with fan" is a little bit vague but i have it enabled and it works how i want it to. If the humidity drops down, the furnace fan and the humidifier both turn on, even if the heater itself is not heating. This was my desired feature. Now you will be able to control all those settings for humidity that were greyed out before. I highly recommend enabling "window protection" if you live in a cold climate. Because this humidifier works really well and it will cause some condensation on your windows (especially upstairs) if you are not careful. Humid air rises! Check your windows and keep an eye on them because if they get moisture on them that means your attic can also get moisture and you really don't want that. I Hope this helps at least one person! Thank you Aprilaire!P.S. I had no water flowing on my humidifier after the first install, but i realized there is a tiny yellow restrictor hole that got plugged with something so i stuck a fine needle in it and water works fine now. I Haven't had an issue with that since. The restrictor is just after the solenoid on my 700 model.”
“After a month of use, it only raised the humidity in my 2300 sq ft house 7%. It is attached to hot water, in the supply duct and turned up to max setting. I am disappointed in it's performance.”
