Humidifiers

The Aprilaire Model 600 Humidifier is a top-performing bypass humidifier and helps you fight dry air all season long. 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.

• Features a built-in bypass damper, which means fewer parts to install
• Delivers up to 50% more moisture than competitive units
• Optimizes humidity levels in your home
• Helps reduce susceptibility to colds, the flu, and other respiratory ailments

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 on-going operating costs.
