MERV 11 PREpleat® Benefits & Features

This MERV11 filter has an 85% or greater average particle size efficiency and 3x higher efficiency on 1-3 micron particles than a MERV8. 1-3 micron particles can penetrate deeply into the lungs and can carry viruses and bacteria, so 3x higher efficiency on these particles is quite significant. Higher efficiency will also better protect your HVAC equipment.
