Koch Filter 16X21FC Fan Coil Air Filter 16x21x1

Product Description

The KOCH FILTER 16X21FC is a 1-inch fan coil air filter designed for exact-fit filtration in fan coil units and air handlers. Measuring 16 inches by 21 inches by 1 inch, it fits snugly into the filter rack to maintain proper airflow across the coil surface. It captures dust, debris, and airborne particulates from return air before they can accumulate on the coil. HVAC technicians and mechanical contractors use this filter as a direct replacement during routine maintenance or system servicing on fan coil and air handler installations.

This filter is suited for residential and light commercial fan coil applications where a 16 x 21 x 1 inch filter size is required. Fan coil units are common in hotel rooms, apartments, office buildings, and multi-family residential buildings where individual zone control is needed. The filter installs in the return air side of the unit to protect the coil from fouling and maintain system efficiency. It is a standard replacement interval item typically swapped during scheduled preventive maintenance visits.
