The new GFX4 includes all the same great features as the GFX3, but now controls the furnace blower motor. Your humidifier will deliver humidity with or without furnace activity to keep humidity levels constant.

Coming This Fall.
NEW! GeneralAire® Model 5500 Steam Humidifier

One model accommodates 110 or 220 V installations. One Cylinder accommodates regular and low conductivity. Small and effective. Designed for ease of installation and complete satisfaction.

NEW! GeneralAire® Model 3200 Evaporative Humidifier

With a reduced cover size, pad frame, and number of openings in the chassis, hot air from the furnace has no chance to cycle and cool before traveling through the Vapor Pad®. Our state-of-the-art low-profile design not only produces higher output, but is smaller in size to accommodate more installation variables.

Coming This Fall

Several models are available for a variety of UV purification solutions. With an FDA Class II medical device classification, installing one now during the flu season just makes sense.
