How It Works

Fan-Powered Performance

1
Sensor Reads
The automatic digital control monitors indoor humidity and outdoor temperature, triggering the humidifier only when needed.
2
Water Flows
The hybrid fan actively pushes air through the HydroCore™ panel — it doesn't rely on furnace airflow alone. This doubles evaporative efficiency and works independently of your HVAC system.
3
Air Absorbs
Dry air from the return duct passes through the moisture-laden Water Panel via the bypass damper, absorbing humidity naturally.
4
Whole-Home
Humidified air is distributed through your existing ductwork to every room — no portable units, no refilling, no maintenance headaches.
Benefits

Why Choose the Aprilaire 720?

Fan-Powered Performance

The built-in hybrid fan actively pushes air through the panel — it doesn't depend on furnace airflow. This means 2× the evaporative efficiency and faster humidity recovery, even in the largest homes.

Industry-Leading Capacity

At 21 GPD, the 720 delivers more moisture than any other Aprilaire evaporative humidifier. High-speed mode maximizes output; low-speed mode reduces noise while still delivering 19 GPD.

Healthier Air

Maintaining 40–60% relative humidity reduces airborne viruses, eases allergy and asthma symptoms, and prevents dry skin and bloody noses all winter.

Saves Energy

Properly humidified air feels warmer at lower temperatures. You can turn the thermostat down a degree or two and still feel comfortable — saving on heating bills.

60% Less Wastewater

The recirculation valve recycles water across the panel, reducing wastewater by 60% compared to previous models. Saves up to 15,000 gallons per year — better for your wallet and the environment.

Protects Your Home

Dry air cracks hardwood floors, splits furniture, peels wallpaper, and loosens joints. A whole-home humidifier prevents thousands in damage every winter.

Buyer Guide

Is the Aprilaire 720 Right
for Your Home?

Your home is over 3,000 sq ft
The 720 is rated for tightly constructed homes up to 6,250 sq ft. Its fan-powered design means it works even when the furnace isn't running — ideal for large open-concept homes, multi-story builds, and homes with extensive woodwork.
You need humidity that doesn't depend on furnace runtime
Bypass humidifiers only add moisture when the furnace blower runs. The 720's built-in fan operates independently, delivering humidity on demand — even during mild weather when the furnace cycles less frequently.
You want the quietest, most efficient option
The 720 offers high and low fan speeds. Low speed delivers 19 GPD with reduced noise — perfect for furnaces near living spaces. High speed maxes out at 21 GPD for rapid humidity recovery.

What's the difference between fan-powered and bypass?
A bypass humidifier relies on your furnace blower to push air through the water panel — it only humidifies when the furnace runs. A fan-powered humidifier like the 720 has its own built-in fan, so it can add moisture independently of the furnace. This means faster humidity recovery, higher capacity, and consistent humidity even during mild weather.
How big of a home can the 720 handle?
The 720 is rated for tightly constructed homes up to 6,250 sq ft — the largest coverage of any Aprilaire evaporative humidifier. For average construction, it covers up to 3,000 sq ft. If your home is smaller than 2,000 sq ft, the bypass 620 is more cost-effective.
Is the fan noisy?
The 720 offers high and low fan speed settings. On low speed, it operates at a quiet hum while still delivering 19 GPD — you won't notice it over normal household noise. High speed is slightly louder but delivers maximum 21 GPD output for rapid humidity recovery. The fan module can be configured left or right to optimize airflow and reduce noise in tight installations.
How often does the Water Panel need to be replaced?
Once per heating season for most homes. If you have very hard water, you may want to replace it mid-season. The digital control includes a service indicator that reminds you when it's time. The Water Panel (Model 10) slides out in seconds — no tools needed. One panel comes included with the unit.
Should I connect it to hot or cold water?
Aprilaire recommends connecting to hot water when possible. Hot water increases the evaporation rate and complements the heat from your furnace. The unit works with cold, hard, or soft water too — but hot water gives the best performance. Note: tankless water heaters may not trigger on the low flow rate, so a standard tank water heater is preferred.
What humidity level should I set?
The ideal range is 35–45% relative humidity in winter. The automatic digital control adjusts based on outdoor temperature — when it's very cold outside, it lowers the target slightly to prevent condensation on windows. Most GTA homeowners set the target around 40% and let the automatic control handle the rest.
