Aprilaire Model 620 Whole House Bypass Evaporative Humidifier
The Aprilaire Model 620 Whole House Bypass Evaporative Humidifier integrates directly into your HVAC system to deliver 18 gallons of humidification per day, to help protect occupants, furnishings, and building materials from dry air.
Available with manual or automatic controls, the Model 620 uses proven bypass technology to quietly distribute humidity whenever your furnace or air handler runs. This large capacity humidifier efficiently recycles water to minimize water usage while maintaining optimal humidification in spaces up to 5,300 square feet.
Key Features and Benefits of the Aprilaire Model 620 Whole House Bypass Humidifier
- High Capacity: The Model 620 is capable of outputting 18 gallons of moisture per day for large homes and light-commercial spaces up to 5,300 square feet.
- Automatic or Manual Controls: You can choose this humidifier as the AprilAire 620A model with automatic digital controls, or the manually controlled AprilAire 620M model.
- Recirculation Valve: Recycles water through the media panel, reducing wastewater by 55 percent and saving up to 4,650 gallons each year for lower utility costs.
- HydroCore Media Panel: The AprilAire HydroCore Water Panel Cartridge snaps into place quickly, cutting maintenance time and helping ensure peak evaporative output all season long.
- Reversible Bypass Module: Left (standard configuration) or right (reconfigured) airflow configurations adapt to tight mechanical rooms, making installation easier with limited return-air space or unique layout constraints.
- Healthy Air System Compatible: The Model 620 integrates seamlessly with Aprilaire ventilation and filtration components, giving you a complete indoor air package from one trusted brand.
Engineered for Efficiency
The Aprilaire 620 takes a practical approach to evaporative humidification by focusing on water use and streamlined upkeep. Unused water is routed back across the HydroCore panel rather than down the drain, cutting waste while maintaining consistent output rates. An adjustable damper lets you fine-tune static pressure for optimal airflow.
Sylvane’s Expert Take
If you need a high-capacity AprilAire humidifier that installs cleanly on existing ductwork and conserves water, the Model 620 is a strong fit. Its reversible bypass module, control options, and large coverage area simplify specification for both new construction and retrofit jobs. We appreciate the water-recycling feature and simple one-piece HydroCore water panel cartridge. Overall, it is an efficient, low-maintenance path to balanced humidity for large spaces.
