AprilAire helps make your home a Healthy Air environment with the Model 400M 17 Gal. Water Saver Humidifier. This whole-house humidifier is designed for homes up to 5,000 sq. ft. delivering optimal relative humidity to balance out the dry, hot air created by furnaces. Its innovative design uses 100% of the water that enters the system, utilizing a unique evaporative process that's perfect for homes with a septic system. Plus, it saves on water and energy costs. The included manual humidistat lets you control the humidity level throughout your home. 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. You'll 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 using the existing blower fan in your HVAC system. The water panel is essential to the process, ensuring the removal of impurities from the water and providing uniform, high evaporation for whole-house humidification. AprilAire invented the whole-house evaporative humidifier in 1954 and this unit is designed utilizing global components. It offers multiple options for installation, making it simple to experience the benefits of balanced humidity throughout your living space.
