Default HVAC return vent

Hello,

I would like to ask if anyone know the return for HVAC by the thermostat should have a filter in it? I know that the one at the system in the garage has a filter so that dust does not make the coils dirty.

Where I am from in VA, we do not have filter at the return vent. It may reduce the dust to go into the duck work; but I am not sure if it prevents or reduces the amount of air returning to the system which may not be good and cause the system work more often.

Thank you.
