Amazon product: Aprilaire Model 500M Manual Whole House Medium Capacity Furnace Humidifier for up to 3,000 Square feet
Customer Reviews:
Perfect! As described. Keep in mind that it’s a product for professional installation therefore you will require some parts not included. If you have a furnace that runs air all the time because of an air quality cabinet be warned not to wire the fan signal wires, it will run the water continually.
