I have been looking for a part number for the air filter for these units with no luck. It is not in the service or operator manual for some strange reason. They are owned by 3M now, and neither set of manuals have this part number.. weird... Thanks if you can help me with a part number.

STABNDBY LED AND 46 TEMPERATURE CONTROL BUTTONS ARE WORKING.
