Koch Filter P412024 Pleated Air Filter 20x24x1 in

Product Description

The KOCH FILTER P412024 is a 1-inch pleated air filter designed for residential and light commercial HVAC systems. Measuring 20 inches by 24 inches by 1 inch, it installs in standard filter slots found in forced-air furnaces, air handlers, and packaged units. The pleated media construction increases surface area compared to flat-panel fiberglass filters, which translates to improved particle capture without excessive restriction to airflow. Licensed HVAC technicians and experienced DIYers install this filter as a routine maintenance replacement to protect equipment and maintain indoor air quality.

This filter fits standard 20x24x1 filter housings commonly found in residential forced-air systems. It is suited for applications where a pleated replacement is specified over a basic fiberglass panel. Typical install locations include return-air grilles, filter racks, and air handler cabinets requiring a nominal 20-by-24-by-1-inch filter. It is a practical replacement for annual or seasonal maintenance schedules.

Installation Notes

Filter replacement is a standard HVAC maintenance task performed by licensed technicians or knowledgeable facility staff. Always set the system thermostat to the off position and confirm the air handler or furnace blower has stopped before opening the filter compartment. Install the filter with the airflow direction arrow on the frame pointing toward the blower. Follow equipment manufacturer guidelines for recommended replacement intervals, typically every one to three months depending on usage and environment.
