Koch Filter P411224 Pleated Air Filter 12x24x1

Product Description

The KOCH FILTER P411224 is a 1-inch pleated air filter sized at 12 inches by 24 inches, designed for residential and light commercial HVAC air handling systems. Pleated media construction increases the effective filtration surface area compared to flat fiberglass panels, improving dust and particulate capture while supporting adequate system airflow. This filter is a standard drop-in replacement suited for forced-air furnaces, air handlers, and packaged units that accept a 12 x 24 x 1 inch filter. Installation requires no tools and is handled by HVAC technicians or qualified service personnel during routine maintenance cycles.

This filter fits systems configured for the 12 x 24 x 1 inch nominal filter size, which is a widely used dimension in residential and light commercial forced-air HVAC equipment. It is appropriate for applications where basic to mid-range particulate filtration is required, including dust, lint, and larger airborne debris. Regularly replacing this filter on a scheduled basis maintains system efficiency and protects downstream coil and blower components from contamination buildup.

Installation Notes

Pleated air filters of this type are installed by HVAC technicians or qualified maintenance personnel. Power down or set the thermostat to the off position before opening the filter compartment to prevent unfiltered air from bypassing the media during service. Confirm airflow direction markings on the filter frame align with the system airflow arrow before seating the filter. Follow the equipment manufacturer and local code guidelines for filter replacement intervals.
