The Vapor Pad is coated with a specialized hydrophilic material that absorbs water. As warm furnace air passes through, the water evaporates into your home. Over time, mineral deposits accumulate and restrict airflow. Attempting to wash the pad will strip away the hydrophilic coating and deform the mesh, rendering the humidifier unable to produce moisture. How often should I change the GA900 Vapor Pad? It is recommended to replace your Vapor Pad 1 to 2 times per humidification season. Homes with heavy heating demand or hard water should inspect and replace the pad more frequently to prevent mineral buildup from choking system airflow. Which humidifier models use this replacement pad? The GA900 fits all GeneralAire 900 and 1000 series whole-home humidifiers. It is the direct replacement for the previous GA19 pad. Which side goes up during installation? Always insert the vapor pad into the housing frame with the black mark positioned on top.
