Is there a difference between a true HEPA filter and a HEPA filter?

The main differences between HEPA-type and True HEPA filter are the filtration efficiency. In general, HEPA-type filter has a 99% efficiency rate of capturing particles as small as 2 microns. True HEPA filter up the game with a better 99.97% efficiency rate at particles as small as 0.3 microns.
