Should the air flow indicator on the filter be pointing towards the inside of the Trane XE90 furnace or to the outside?Post created: 2014-04-17 Type of Equipment: Furnace Views: 207

If I understand the inflow/outflow duct work correctly the airflow indicator arrow on the filter should point inward but want to make sure.
