That information about filtering is stellar..thanks so much!
I don't really do nitrous anymore, unless I am a little stoned or drunk, chillin out, and someone drags out a whippit. It gives me a bit of a rush of mellow, and makes me talk like Darth Vader ("Together we can rule the Galaxy, as father and son"). I am not a big fan of the asphyxiation part though. If I lose any more brain cells, I may go into deficit!
