Aprilaire Model 500 Small Bypass Whole House Humidifiers

Chronic low humidity in your home can undermine your indoor comfort and even cause costly damage to your home’s interior. Improve your comfort and protect your home during dry winter months (or year-round) when you use the Aprilaire Model 500 or 500M Whole House Humidifier. This bypass humidifier works with your HVAC or furnace system to deliver comfortably humidified air throughout every room of your home. It functions like an evaporative humidifier, evenly distributing 12 gallons of moisture per day. That’s enough to humidify tightly sealed homes up to 3,000 square feet, average sealed homes up to 1,500 square feet, and loosely sealed homes up to 750 square feet. How It Operates When connected to your HVAC system, the Aprilaire 500 and 500M Bypass Whole House Humidifiers moisturize your home's air using a natural evaporation process. When the humidifier controller triggers a need for more humidity, water flows from the connected water line into a distribution tray. The water flows over Aprilaire’s patented Water Panel evaporator where moisture from the distribution tray is evaporated into the incoming dry air. Humidified air is then distributed throughout your home via your HVAC system’s return duct and with the help of the blower. Ideal for Smaller Homes-Fewer Parts To Install The Aprilaire Model 500 Whole House Humidifier is ideal for smaller homes, requires fewer installation parts, and needs only simple annual maintenance. Bypass Damper: The model incorporates a built-in bypass damper and right/left discharge change-over for easier installation and operation. Built-In Drain: It’s also equipped with a built-in drain to flush mineral build-up from the machine. Plus, no standing water inside the unit means humidified air always remains fresh and clean. Maintenance is a fast once-a-year process. Two Aprilaire 500 Models Available Model 500: Comes with a digital humidity controller that supports both automatic “set it and forget it” operation and manual humidity control.

Thorough instructions and guidance for setting and adjusting an ideal humidity level using the controllers are included with each model.
