The air distributed into the home is referred to as "supply air". The supply air is forced by the blower (fan) through the heat exchanger and/or evaporator coil to be "conditioned". Then, through the plenum, it goes into our main supply duct. (Trunk lines, photo 3.) The supply duct is sized based on the amount of air it must move.Then you could easily figure what size filter you need for that CFM of airflow to get say 300 ft./m of airflow velocity through a new filter, being that it is the fiberglass filter. We will say in the cooling mode you want to flow 1250 CFM of air volume for a 3 ton AC or heat pump through the system; 1250÷300 is 4.1666 ft.² of free air area ...Originally Posted by tigergrad97. 12" -14"...by appearance anyway. 2-14" would be ok for 3 tons (depending on length and bends/turns. So your a bit small for 3 tons if 1 is 12" and the other 14". Which may be why your current 3 ton struggles on some days. Reply. 11-10-2010, 09:09 PM #10. tedkidd. Professional Member*.

The supply plenum gets filled with cooled or heated air by the HVAC system, which is then ultimately sent through the ductwork. When the cooled or heated air enters a room, the already-present air in the space gets pushed into another series of ducts. These ducts then transport the returned air to the return plenum.
