All HEPA filters are rated MERV 17 or higher. True HEPA: A consumer air filter labeled True HEPA must meet the DOE standard closest to the DOE standard for a HEPA air filter. With its highest efficiency, it must remove 99.97 percent of all particles that are 0.3 microns in size. InvisiClean, Aviano, Medify, Airthereal, Honeywell, Winix, GermGuardian and Levoit make air purifiers labeled True HEPA.
Eureka also markets vacuum filters such as True HEPA. The Aviano claims to filter particles “as small as 0.03 microns, but that can be a typo in its marketing materials. H13-H14 HEPA filters are within the highest level of HEPA air filtration and are considered medical grade. A true HEPA filter is a 17, the HEPA standard.
This is the most common classification for household HEPA air purifiers. A HEPA filtration system is good for all allergens.

However, in real world use, you may be misled by many brands of air purifiers that claim to have the True HEPA filter. There is a common assumption that the air gap between the fibers should be as small as 0.3 microns, so the True HEPA filter can capture anything larger than this size.
These filters can only capture particles as small as 2 to 5 microns, which means a decrease of more than 600% in the efficiency of a True HEPA filter. However, to be considered a true HEPA filter, a HEPA air filter must be certified to remove 99.97% of all microscopic particles up to 0.3 microns in size, which is the smallest particle size that reaches the lungs. When looking for portable air purifier solutions for your facility, it's essential to know the difference between HEPA, true HEPA, HEPA-type, and other HEPA filters.
