HEM2 has no option for auto-removal of imported HHs from the poker sites' HHs folder. When I play, it imports HHs but the HHs stay in the poker site's (e.g. PokerStars') HHs folder forever. (I think there used to be an option for auto-removal as I have opted off it at some point but I don't remember if it was HEM2.) There is an option to auto-archive after 15 minutes but no option for auto-removal as mentioned.
