Koch Filter P412428 Pleated Air Filter 24x28x1

Product Description

The KOCH FILTER P412428 is a 1-inch pleated air filter sized at 24 x 28 x 1 inches, designed for HVAC systems that require non-standard filter dimensions. The pleated media construction increases surface area compared to flat fiberglass panels, supporting effective particulate capture while maintaining adequate airflow across the air handler or furnace. This filter is installed by HVAC technicians and qualified service professionals during routine maintenance or filter changeout service calls.

This filter fits residential and light commercial HVAC applications where the standard 1-inch filter slot calls for a 24-by-28-inch frame. It is well suited for forced-air systems including gas furnaces, air handlers, and heat pumps that use a return-air filter rack or cabinet-mounted filter slot. Its non-standard dimensions make it a targeted replacement for systems that cannot accept common off-the-shelf sizing.

Key Features

• Non-standard 24 x 28 x 1 inch sizing for specialized HVAC filter slots
• Pleated media design increases dust-holding capacity over flat panel filters
• 1-inch depth fits standard single-slot filter racks and cabinet returns
• Supports airflow balance while capturing airborne particulates

Compatibility

Designed as an OEM-style replacement pleated air filter for residential and light commercial forced-air HVAC systems requiring a 24 x 28 x 1 inch filter.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel during scheduled maintenance. Power down the air handler or furnace at the disconnect or thermostat before removing the old filter. Insert the new filter with the airflow arrow on the frame pointing toward the blower. Follow local codes and the equipment manufacturer's service guidelines for filter replacement intervals.
