That air conditioner hanging from the window of your apartment has a filter, likely a thin layer of foam attached to the inside of it. So does the central air unit that pushes refrigerated air through the ducts of your home, only it’s probably a cellulose or fiberglass style that slides in next to the main ductwork.
