Description
The Field Controls 731011625 Filter is a folded filtration unit rated at MERV 13, measuring 16 by 25 by 4 inches with a 3.75-inch actual depth, capable of capturing airborne particles as small as 0.3 to 1.0 microns, including fine dust, pollen, mold spores, and bacteria-carrying droplets. The extended depth increases media surface area, allowing the filter to hold a higher particle load before airflow restriction affects system performance. Within HVAC systems, this filter sits in the return air section of an air handler or furnace, screening the incoming airstream before it passes over the coil and blower.
