Koch Filter 18X30X1 Pleated Air Filter Merv 8

Product Description

The KOCH FILTER 18X30X1 is a medium-efficiency extended-surface pleated panel air filter rated MERV 8. It uses a specialized fiber blend developed specifically for extended-surface applications, delivering mechanical filtration with high dust-holding capacity and low pressure drop. The actual dimensions are 17.5 inches x 29.5 inches x 0.75 inches within a nominal 18 x 30 x 1 inch frame. With an airflow capacity of 1,125 CFM, this filter maintains its MERV 8 rating before and after conditioning when tested to ASHRAE Standard 52.2-2012. It is suitable for residential and light commercial air handling systems and is sold as a single unit.

This filter is installed in forced-air HVAC systems where a nominal 18 x 30 x 1 inch filter slot is used. It fits standard return-air grilles and filter racks configured for that nominal size. The MERV 8 rating makes it appropriate for environments where capture of lint, dust mites, mold spores, and fine dust is a priority without imposing excessive static pressure on the air handler. Replacement is recommended every three months under typical residential operating conditions.

Compatibility

Designed as a drop-in pleated panel filter replacement for forced-air HVAC systems requiring a nominal 18 x 30 x 1 inch filter in a return-air grille or filter rack.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Power down or set the thermostat to the off position before replacing the filter to prevent unfiltered air from bypassing into the system during changeout. Confirm the actual slot dimensions match the filter actual size of 17.5 x 29.5 x 0.75 inches before inserting. Airflow direction arrows on the filter frame must align with the direction of air movement toward the air handler.
