wtf does this even achieve? it blows semi sterile air into a contaminated room. the clean air coming out will be contaminated within seconds... literally wtf is the point of this? there isn't even a prefilter to prevent massive build of shit onto the hepas.  this is completely fucking asinine secondly, systems that blow sterile air into a room already exist and are mounted to the wall or ceiling. they aren't cheap either, but their application is specifically for clean rooms and the like. attempting to do this for a classroom is like pissing in an ocean of piss. i hate niggers so much it's unreal.
