What is True HEPA? What makes it so special?
HEPA stands for “High Efficiency Particulate Arrestor.” True HEPA refers to a high-efficiency class of HEPA filter media rated 99.97% efficient at 0.3 microns. What makes True HEPA special is its high particle capture efficiency. True HEPA filtration has been used for many years in nuclear facilities, manufacturing clean rooms and medical facilities where clean air is absolutely required. The American Lung Association refers to HEPA as the most efficient mechanical filters for removing small particles, which can be breathed deep into the lungs.
