Doesn't "HEPA" refer to the quality / fineness of the filtering?

My Dyson cleaner has a HEPA filter, I think thats a trade name to a filter element for catching dust and dirt etc. It seem,s cruise ships are fitting Ultra Vilolet system to kill them little bugs off in there air conditioning systems air handling units.
