High-efficiency particulate air (HEPA) filters are at the pinnacle of residential air filtration, as filters must meet stringent standards before being designated as HEPA-compliant. Specifically, any filter labeled as HEPA must capture at least 99.97% of all particles measuring 0.3 microns or larger.
To provide perspective, there are 25,400 microns in a single inch; a single bacterium is no smaller than 0.3 microns in diameter, with many being as large as 60 microns. This scale demonstrates the extreme capability of HEPA filters and how stringent these standards really are. For more information, contact an air conditioning service in Lady Lake FL.
