AprilAire 500M Whole House Humidifier with Manual Control

Say goodbye to dry indoor air with the Aprilaire 500M Bypass Humidifier with Manual Control working through your HVAC system. This humidifier is designed to add balanced humidity to your home by working directly with your HVAC system. Built for smaller homes, this whole-home solution helps maintain more comfortable indoor air by introducing moisture as heated air circulates through your ductwork. Dry indoor air can lead to a range of issues, from discomfort like dry skin and irritated sinuses to static electricity and potential damage to wood furnishings. The Aprilaire 500M helps address these concerns by delivering consistent humidity throughout the home, supporting a more comfortable living environment during dry seasons.

The bypass-style humidifier uses the HVAC system’s airflow to distribute moisture and maintain even coverage across multiple rooms. With a built-in bypass damper, installation is more streamlined, which reduces the need for additional components while allowing for simple seasonal adjustments between heating and cooling months. The included manual humidistat gives you direct control over humidity levels, allowing you to adjust settings based on your comfort preferences and changing conditions. Designed for flexible installation, the unit can be mounted on either the supply or return duct and configured for left or right-side orientation. With dependable performance and straightforward operation, the Aprilaire 500M is an effective way to manage indoor humidity and improve overall comfort throughout your home.

Note: professional installation is required to ensure proper installation, operation, and regular maintenance.
