AprilAire helps make your home a Healthy Air environment with the Model 300 13 gal. Evaporative Humidifier. This whole-house humidifier is designed for homes up to 3，900 sq. ft.， delivering optimal relative humidity to balance out the dry air experienced in colder climate regions. Versatile design can be used in homes heated with mini-splits， boilers， radiant heat and other ductless systems and homes heated with ducted， forced-air systems where a duct-mounted humidifier is not practical. Use the digital humidistat to set the target humidity level and the onboard sensor actively monitors your home's air， automatically turning on and off the unit as needed. While balanced humidity exists between 40-60%， it's important to remember that outdoor temperature and other home factors will impact what relative humidity level is attainable and recommended for your house. Enjoy balanced humidity thanks to the evaporative process， which works by passing hot， dry air from your furnace over the interior water panel to add moisture before returning the humidified air into your home with the built-in fan. The water panel is essential to the process， ensuring the removal of impurities from the water and providing uniform， high evaporation. AprilAire invented the whole-house evaporative humidifier in 1954 and this utilizing US and global components. Multiple options for installation make it simple to experience the benefits of balanced humidity.
