Automatic High Output Furnace Humidifier. The Aprilaire Model 700 Humidifier is a whole-home solution that helps you achieve total comfort through humidity control. 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.
