The LUKJAN CA50251414A is a furnace filter box designed for use in residential and light commercial HVAC installations. This sheet metal filter box provides a dedicated housing for air filtration at the furnace or air handler, maintaining clean airflow through the system before it reaches the heat exchanger or coil. Measuring 14.5 inches by 25 inches by 14 inches, it accommodates standard filter sizes in that footprint. HVAC installers use this type of box during new construction or replacement work when a proper filter section is needed in the supply or return duct configuration.
This filter box is suited for furnace and air handler applications where a dedicated filter housing needs to be integrated into the duct system. It is listed under the furnace boxes category and fits within standard furnace and air handler fitting configurations. The 14.5 x 25 x 14 inch size makes it compatible with common residential duct layouts. It is referenced under model AGM270142514H, which may be used for cross-reference purposes when sourcing a replacement or matching an existing installation.
Referenced as a replacement or equivalent for AGM270142514H (AGM 270 series). Designed as an OEM-style furnace filter box for residential and light commercial furnace and air handler installations.
Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes. Shut down and de-energize the furnace or air handler before cutting into existing ductwork or making connections. Secure all seams with appropriate sheet metal screws and duct sealant to prevent air bypass around the filter. Verify that the installed filter size matches the box dimensions before returning the system to service.
