Filters are rated using the MERV (Minimum Efficiency Reporting Value) scale, which ranges from 1 to 20. Additionally, a noticeable decrease in airflow from the vents or an increase in dust accumulation on surfaces are clear signs that the filter is no longer performing its duty.
Observing the filter visually is the best practice; if you can no longer see light through the mesh, it is time for a replacement regardless of the calendar date. Slide the new filter into the housing, ensuring the arrow points toward the blower motor to maintain proper airflow dynamics.
