A return duct sized equal to the fan coil unit return opening links to a filter box housing a MERV 13 filter with a minimum twenty-four-inch air opening. The filter box requires a flange connection to allow filter removal through the side or bottom, coordinated with field conditions. A twenty-four by twenty-four-inch access door provides access for fan and cooling coil servicing. The return air opening is equipped with a wire mesh screen and one-inch sound lining.
