Generalaire 4401 Expandable Media Assembly Air Cleaner

Product Description

The GENERALAIRE 4401 is an expandable micro fiber media assembly designed as a direct replacement filter for the GeneralAire AC-4 whole-house air cleaner. Measuring 25 inches in length by 6 inches in height, this media assembly captures airborne particulates circulating through residential forced-air HVAC systems. The expandable design allows the media to unfold and fill the filter housing, maximizing surface area for particle capture. HVAC technicians and service professionals install this media during routine maintenance intervals to restore air cleaner performance and maintain indoor air quality across the connected duct system.

The 4401 media assembly is used in whole-house air cleaner applications integrated into residential forced-air systems. It is a maintenance replacement part intended for the GeneralAire AC4 air cleaner unit. Typical installation occurs during seasonal HVAC service calls or when media loading reduces airflow through the filter housing. The expandable micro fiber construction suits applications where a high-surface-area media is needed within a compact filter cabinet footprint.

Installation Notes

Installation is performed by a qualified HVAC technician. Before replacing the media, shut down the air handler or furnace at the unit disconnect or breaker to eliminate airflow through the housing during service. Remove the spent media assembly, insert the new 4401 in the correct orientation per the filter cabinet markings, and confirm the housing door latches securely before restoring power. Follow local codes and the equipment manufacturer guidelines for recommended media replacement intervals.
