Product review (5 stars): Exactly what I needed.
Because of my furnace and ducting set up, I was very limited on where I could put a bypass humidifier. This product was exactly what I needed. It is super simple and it works. Our humidity has gone from 10% average to 40%. It has only been a week and I am hoping the it can get higher yet so that the humidifier won't be running every time the furnace is. The humidistat is basic but that is fine with me. There is a lack of wire that come with it but I had some anyway.
