The Aprilaire APR 400 is a bypass humidifier that integrates seamlessly with central heating and cooling systems. Its purpose is to regulate and optimize indoor humidity levels throughout the year, particularly during periods of low humidity, such as winter.

Installation of the APR 400 involves connecting the humidifier to the ductwork of your furnace and a water supply. The bypass design ensures that air from the heating or cooling system passes through a water panel, where it absorbs moisture before being distributed throughout the home.

One of the primary benefits of using a humidifier like the APR 400 is the improvement of indoor air quality. Proper humidity levels can alleviate dry skin, reduce static electricity, and even help preserve wooden furniture and musical instruments.

Additionally, monitoring and adjusting humidity levels based on seasonal changes will help you make the most of your Aprilaire APR 400 and create a comfortable living environment.
