So did your new filter have arrows on one edge of the filter? If so, you failed to show us the arrows. Did you point the arrows up or down? If it said "up" next to the arrows then the arrows should point up because the word "up" indicates which side goes up. However, if it said "air flow" next to the arrows then the arrows should point down because the direction of air flow is downward. Without that information this video is incomplete.

@@njsongwriter it’s a fabric filter that can support airflow in either direction.. But thank you for watching.
