      I like the fact that it matches my Lennox furnace air filter but the humidistat control was dead-on-arrival. Had to buy a Honeywell -stat. Now functions.

      I installed this a week ago and couldn't be happier. I live in a 5 year old 2200sqft. home. The directions were detailed enough for the install. Would've been nice to have the wiring portion a little more specific. Accidentally had it up too high the first night, made all the windows sweat!

      I have to install this humidifier by instruction recommendation on Lennox furnace. The thermostat is setting at 45% of humidity, but the best what we can get in our rooms - 29%-31%, an average is 25%. The house is about 1300 sq.ft. and the system is using the hot water. I'm very upset; the system doesn't work as promised.
