Aprilaire Whole-House Humidifiers (2024)

• Aprilaire 400 Whole House Humidifier

Automatic WATER SAVER Furnace Humidifier
The Model 400 is a drain-free humidifier, featuring evaporative technology to minimize water use.

Aprilaire introduced the first evaporative humidifier for forced air furnace systems back in 1954. Since that time, Aprilaire continues to lead the industry in whole-home humidification systems. Our evaporative humidifiers work by piping water into the distribution tray located at the top of the humidifier. The water is uniformly distributed across the width of the tray and through a scientifically designed system of outlets. It flows by gravity over the water panel evaporator. Dry, hot air from the HVAC system is moved through the moisture-laden water panel evaporator. Natural evaporation takes place, the water is turned to vapor, and the humidified air is circulated throughout your home.

Included in the box: Installation instructions and template, humidifier with built-in bypass damper, 24 VAC transformer, automatic digital humidifier control, and outdoor temperature sensor, saddle valve, solenoid valve, and water panel

• Aprilaire 800 Whole House Steam Humidifier

High Output Humidifier

Aprilaire Model 800 steam humidifiers use electrode technology and are simple to install, operate, and maintain. With electrode technology, electrical current flows between submerged electrodes, resistance of the water to the electric current heats the water. The submerged electrodes are found in a replaceable canister. At the end of a humidifier season, the canister – including the electrodes, is replaced. No cleaning, no scrubbing, simply replace the canister and you’re ready for the next humidifier season. Electrode technology requires impurities in the water to promote the transfer of electricity. For this reason, water filtration is not required with electrode technology, minimizing the complexity of the installation and ongoing operating costs.
