Hepa is held to a higher standard…think of it like a coffee filter. If you made coffee with a piece of screening (like a screen door) that’d be like a regular filtre…it’ll only catch the big stuff. Now think of a hepa filter like using 2 regular coffee filters…it’ll filter out more of the smaller bits.
