AprilAire, a leader in Healthy Air solutions, has unveiled the Model 620 Large Bypass Evaporative Humidifier, the most innovative product in its category since AprilAire invented bypass humidification in 1954. Expanding the HydroCore™ Humidifier Series, the Model 620 introduces groundbreaking efficiency, water savings, and simplified installation—offering clear benefits for both contractors and homeowners.
Performance and Efficiency
The AprilAire 620 delivers 18 gallons of humidification per day while using 55% less wastewater compared to previous models. Its innovative recirculation valve distributes 3X more water across the panel for optimal saturation, reducing drain water and saving up to 4,650 gallons per year—equivalent to 35,000 plastic water bottles.
These improvements position the 620 as one of the most sustainable humidifiers available, helping families maintain healthy indoor environments while conserving resources.
Contractor-Friendly Design
The 620 integrates contractor feedback to streamline installation and servicing:
- All-in-one HydroCore™ Water Panel Cartridge allows for annual replacement in about one minute.
- Modular design supports faster installs with fewer steps.
- New airflow damper adjustment optimizes performance for high-pressure systems.
- Catch-all drain system prevents leaks by directing all water safely into the basin.
These features reduce installation time, minimize callbacks, and improve contractor profitability.
Homeowner Benefits
Balanced indoor humidity is proven to:
- Reduce the incidence of respiratory infections
- Minimize allergy and asthma symptoms
- Protect wood furniture, flooring, and valuables from damage due to dry air
By integrating into the AprilAire Healthy Air System®, the Model 620 provides a whole-home solution for maintaining optimal Indoor Air Quality (IAQ).
Strategic Importance
