This AprilAire humidifier, model 720A, is a furnace-mounted whole-home humidifier designed to maintain optimal humidity levels throughout the entire house. Installed next to the furnace, this model introduces moisture directly into the HVAC system’s ductwork, ensuring even distribution of humidity in every room — unlike portable humidifiers that only cover a small area.
AprilAire is one of the most trusted and popular brands in the humidifier market, known for high-quality, reliable performance. The 720A model has a daily capacity of up to 21 gallons, allowing it to efficiently humidify homes up to 6,250 square feet, depending on insulation and climate. It runs on 24VAC, drawing power from the furnace without requiring a separate electrical connection.
What sets the 720A apart is its automatic digital control system, which uses dual sensors (indoor humidity and outdoor temperature) to continuously monitor and adjust the humidity level for optimal comfort and energy efficiency. This “set and forget” feature makes it ideal for homeowners seeking low-maintenance air quality improvement, especially those with respiratory conditions like asthma.
The AprilAire 720A comes with a 5-year limited parts warranty, and with proper use and regular maintenance, it has an expected lifespan of 7 to 10 years, making it a durable and dependable solution for whole-home humidification.
