Koch Filter P411424 Pleated Air Filter 14x24x1

Product Description

The KOCH FILTER P411424 is a pleated air filter designed for residential and light commercial HVAC systems that require a wider-format filter media. Sized at 14 inches by 24 inches by 1 inch, it fits standard filter slots and returns without modification. The pleated design increases surface area compared to flat fiberglass panels, supporting effective particulate capture while maintaining adequate airflow through the system. Licensed HVAC technicians and knowledgeable DIYers install this filter as part of routine preventive maintenance on forced-air heating and cooling equipment.

This filter is suited for forced-air systems using a 14 x 24 x 1 inch filter slot, found in a range of air handlers, furnaces, and packaged HVAC units in residential and light commercial applications. It is particularly appropriate for systems that run continuously and require a filter that balances dust-holding capacity with low pressure drop to avoid restricting airflow across the blower.

Key Features

• Pleated media design provides increased surface area for improved dust and particulate capture
• Nominal size of 14 x 24 x 1 inches fits standard filter slots without modification
• Supports proper airflow balance across forced-air HVAC equipment
• Suitable for routine replacement in residential and light commercial systems

Compatibility

Designed as an OEM-style replacement pleated air filter for residential and light commercial forced-air HVAC systems accepting a 14 x 24 x 1 inch filter.

Installation Notes

Filter replacement is performed by HVAC technicians or qualified building maintenance personnel. Always shut down the HVAC system at the thermostat and disconnect power before opening the filter access panel. Insert the filter with the airflow direction arrow pointing toward the blower. Follow local codes and equipment manufacturer guidelines for recommended filter replacement intervals.
