A MERV13 filter removes greater than 50% of particles sized 0.3 to 1.0um per the chart in the article below. If a particle in this range passes the first time greater than 50% should have been removed. On a second pass, will it be 50% of the remainder? This would imply after the air has been cycled through at least twice a MERV13 h as removed at least 75%, correct?
