The GENERALAIRE 401-13156 is an expandable, high-efficiency air cleaner media filter rated MERV 11, designed for whole-home air cleaning systems. It filters airborne particulates including humidifier dust, lead dust, auto emissions, and milled flour at 65 to 79 percent efficiency for particles in the 1 to 3 micron range and 85 percent efficiency for particles in the 3 to 10 micron range. The expandable media design increases surface area for effective filtration without excessive airflow restriction. HVAC technicians and qualified installers use this filter as part of routine preventive maintenance on whole-home air cleaner systems.
This media filter is intended for use in the GENERALAIRE RP 2400 air cleaner system. It is suited for residential applications where indoor air quality is a priority, particularly in homes with occupants sensitive to dust, fine particulates, or common airborne contaminants. The MERV 11 rating makes this filter appropriate for general residential environments requiring above-standard filtration performance without stepping up to higher-restriction media.
Designed for use with the GENERALAIRE RP 2400 air cleaner system.
Filter replacement should be performed by a qualified HVAC technician or trained service professional. Shut down the air handler and air cleaner system before opening the cabinet or removing the existing media filter. Follow the manufacturer's recommended replacement interval and inspect the filter housing for debris before installing the new media. Dispose of the used filter in accordance with local waste guidelines.
