Hi Gary,

   I called OEM parts, the person I spoke to had no
idea that some of the AC line filters came from
decomissioned screen rooms. He invited me to come down
and take a look at the inventory, being that I'm in
Massachusetts I declined.
  Do you know how I can specify the screen room
filters?

Thanks,
Warren
