Founded in 1954 and headquartered in Madison, Wisconsin, Aprilaire invented the first residential humidifier and has been producing whole-home indoor air quality equipment for over 70 years. The HydroCore Series includes the Model 620 bypass humidifier at 18 gallons per day and the Model 720 fan-powered humidifier at 21 gallons per day. The E050 Series whole-home dehumidifier is rated at 50 pints per day. Aprilaire products are made in the USA. HVAC contractors and residential indoor air quality specialists specify Aprilaire products for whole-home humidity control, air purification, and ventilation applications.

Product Lines

HydroCore Series Whole-Home Humidifiers

Aprilaire's HydroCore Series covers bypass and fan-powered whole-home humidifiers for integration with forced-air residential HVAC systems. The Aprilaire Model 620 is a bypass humidifier rated at 18 gallons per day; the Aprilaire Model 720 is a fan-powered humidifier rated at 21 gallons per day with its own blower motor for independent operation. Specified for whole-home humidity control in dry climates and heating-season applications.

Whole-Home Dehumidifiers

Aprilaire's whole-home dehumidifier line includes the E050 Series at 50 pints per day, measuring 10 by 10 by 25 inches and weighing 46 pounds, for basements, crawl spaces, and mechanical room installation. The Aprilaire E050W adds Wi-Fi control via the Aprilaire Connect app. Specified for residential applications where HVAC cooling doesn't provide sufficient dehumidification or where year-round dehumidification is required.

Air Purifiers

Aprilaire's whole-home air purifier line uses an Event-Based air cleaning approach, integrating with the residential HVAC thermostat to run air cleaning cycles based on occupancy and household events. The Aprilaire Healthy Air Monitor senses indoor temperature, humidity, and particle levels to inform purifier operation. Specified for whole-home particle reduction in forced-air systems where standalone room air purifiers don't cover the full conditioned space.

Ventilators

Aprilaire's ventilator product line provides controlled fresh air delivery to comply with ASHRAE Standard 62.2 residential ventilation requirements. Aprilaire ventilators integrate with the residential HVAC system to deliver outdoor air on a controlled schedule, diluting indoor contaminants. Specified for new construction and existing home ventilation upgrades where ASHRAE 62.2 compliance is required.

Thermostats

Aprilaire's thermostat line includes whole-home control systems managing heating, cooling, humidification, dehumidification, ventilation, and air purification through a single interface. Designed for compatibility with Aprilaire IAQ products and standard residential HVAC equipment, specified when the system includes multiple Aprilaire IAQ products that benefit from integrated control.

Why Contractors Specify Aprilaire

Aprilaire invented the first residential humidifier in 1954 and has been producing whole-home indoor air quality equipment for over 70 years from Madison, Wisconsin. Aprilaire products are made in the USA. The HydroCore Series humidifier line covers bypass (Model 620, 18 GPD) and fan-powered (Model 720, 21 GPD) configurations for residential forced-air systems. The E050 whole-home dehumidifier at 50 pints per day covers the capacity range for residential whole-home dehumidification. Aprilaire's product line spans humidification, dehumidification, air purification, ventilation, and thermostats within a single manufacturer catalog.

How to Choose an Aprilaire Product

The most important decision variable when selecting an Aprilaire humidifier is the humidifier type: bypass or fan-powered. Aprilaire bypass humidifiers (Model 620) require the furnace blower to circulate humidified air and suit installations where the blower runs continuously during heating season. Aprilaire fan-powered humidifiers (Model 720) incorporate their own blower motor for independent operation, appropriate when the blower doesn't run continuously or higher moisture output is needed.

For dehumidification, the Aprilaire E050 Series at 50 pints per day covers most residential basement and whole-home applications; the E050W adds Wi-Fi control. For air purification, Aprilaire air purifiers with Event-Based cleaning are specified for whole-home particle reduction in forced-air systems. For ventilation, Aprilaire ventilators are specified for ASHRAE 62.2 compliance in new construction or existing home upgrades. Consulting Aprilaire's sizing tools and technical documentation confirms the appropriate model for the home's square footage, HVAC configuration, and IAQ objectives.

FAQs

Where are Aprilaire products manufactured?
Aprilaire products are made in the USA. The company is headquartered in Madison, Wisconsin, where Aprilaire invented the first residential humidifier in 1954.
What warranty does Aprilaire offer on its whole-home humidifiers and dehumidifiers?
Aprilaire warranty terms vary by product. Specific warranty documentation for HydroCore Series humidifiers, E050 dehumidifier series, and other Aprilaire products is available through Aprilaire's official product resources and the authorized Aprilaire dealer or contractor.
What's the difference between the Aprilaire Model 620 bypass humidifier and the Aprilaire Model 720 fan-powered humidifier?
The Aprilaire Model 620 is a bypass humidifier rated at 18 gallons per day that requires the furnace blower to circulate humidified air. The Aprilaire Model 720 is a fan-powered humidifier rated at 21 gallons per day with its own blower motor for independent operation. The Model 720 is appropriate when higher moisture output or independent blower operation is needed; the Model 620 suits standard bypass installation where the furnace blower runs continuously during heating season.
What capacity Aprilaire dehumidifier is right for a basement installation?
The Aprilaire E050 Series whole-home dehumidifier at 50 pints per day (10 by 10 by 25 inches, 46 pounds) covers the capacity range for most residential basement and whole-home dehumidification. The appropriate capacity for a specific basement depends on the space size, moisture load, and climate zone. The E050W adds Wi-Fi control via the Aprilaire Connect app.
Is the Aprilaire E050 dehumidifier compatible with the Aprilaire thermostat?
The Aprilaire E050 whole-home dehumidifier is designed for integration with residential HVAC systems and Aprilaire controls. Compatibility between the E050 and a specific Aprilaire thermostat depends on the thermostat model and wiring configuration — consulting Aprilaire's product compatibility documentation and installation guides confirms the appropriate control interface for a specific system.
What Aprilaire product is right for a new construction home that needs ASHRAE 62.2 ventilation compliance?
For a new construction home requiring ASHRAE 62.2 mechanical ventilation compliance, Aprilaire's ventilator product line provides controlled fresh air delivery integrated with the residential forced-air HVAC system. The specific ventilator model depends on the home's square footage, occupancy count, and the ventilation rate required by ASHRAE 62.2 for the specific climate zone.
