An oversized filter won't sit properly, causing air

your HVAC system.

It should fit snugly with no gaps, but not so
tight that it's difficult to insert or remove.
Proper Filter Installation
Install the filter with the airflow arrow pointing
toward the HVAC system's blower, matching
the airflow direction inside the unit.
Consequences of Incorrect
Installation
Restricts airflow, reduces efficiency, increases
energy bills, and can allow dust to bypass the
