How The Aprilaire 300 Works

A self-contained evaporative humidifier, the Aprilaire 300 draws air into the unit with a fan. The air then goes through evaporative humidification by passing over a wet water panel before being released into your home. Humidification continues until your set point is reached.

When the onboard humidistat senses that the humidity level has dropped below your set point, the humidification process starts over again.
