Review on Aprilaire 600 Whole Home Humidifier: Automatic High Output Furnace Humidifier for Homes up to 4,000 Sq. Ft. by Veronica Johnson

Excellent home system. I have two of these, one for the house and one for the parents. The installation is not something I would recommend for a beginner. Help guides are full until it comes to wiring. The wiring isn't clear unless you have a little experience or knowledge working with or on stoves. There are a few YouTube videos that walk you through the process, which again lacks thoroughness in the wiring part. If you have any questions, the technical support is very helpful.
