J. T. Faull. MERV means Minimum Efficiency Reporting Value (MERV) and is an industry standard that measures the overall effectiveness of air filters. And the pressure drop measurements show that the air was moving through it easily, too. A 1" MERV 13 pleated filter has a pressure drop of around 0.27, and a 1" MERV 8 has a pressure drop of around 0.14. Higher pressure drop = less airflow.
