Sepia-toned photo of a room containing the airmaze filters within Crowley Milner's, taken from a photo album of air conditioning installations done by the Detroit Ice Machine Company in 1937. Several large walls of filters are in the room. Shutters are on the group on the immediate right. Duct work runs along the floor. A door is positioned in the center of the wall on the right. "M-2020," is printed in the lower left corner of the photo, corresponding to the description "Airmaze Filters," on the table of contents page (2008.039.003). The photo is mounted on a linen photo album page with a flap on the left hand side with three holes for binding.
