That's cool but if you blow compressed air through it anywhere near your nose, it kind of defeats the purpose of using a HEPA filter in the first place.
I skip the compressed air step. If you simply knock most of the dirt and dust off of one of those things, the vacuum sucks like Nickleback once again. Those filters have a lot of area.
