My patent-pending lung to 100mm duct adapter makes an excellent pre-filter, absorbing large particulates into your bloodstream before passing on the excess to my cludgy filter box I made a few months back.
They say there's a significant overlap between the dumbest human and the smartest bear. This disclaimer is for you smart bears out there: This video is a joke, I did not actually use it and no, I will not be sharing this design with you. It's a trade secret and highly proprietary.
Maybe check out my previous video where I made the filter box if you want more stupid jokes, and the CTRL ONE if you want something more serious.
