The A-2500 HEPA units feature 3-stage filtration including HEPA 99.97%.  The HEPA filter at the end of the unit before NPBI populates the air is a MERV 17, and filters out airborne pathogens and particles.  This unit also features a MERV 15, 95% efficient bag filter which acts as a second line of defense to add even greater filtration of both large and small particles. 

The purpose of the bag filter is to extend the life of the more costly HEPA filter and add filtration.  At the air intake side of the machine is a washable, MERV 8 pre-filter pad.  This spongy pad filters out the largest particles and dust to keep the large filter protected and give them a longer life.
