Check the whole fit.

Match actual width, height and depth to your opening and seal. A shared nominal size alone does not prove compatibility.

Check system airflow before upgrading. If airflow is already weak, have the filter and system checked. A high-MERV one-inch filter needs particular care; a lower printed resistance does not guarantee suitability.

Test context and interpretation

* Manufacturer maximum-rated airflow marker. This does not establish your installed airflow.

Printed initial resistance; not an independent measurement. Other test conditions unestablished.

Filter differential pressure is only one part of system resistance. These points do not establish your delivered airflow, fan energy use, loaded performance or safe service interval. No interpolation is applied.
