This is going to be the strangest question that was ever used to start an article: Have you ever blown your nose after having worked in the shop all day? It’s gross, isn’t it? All that sawdust floating around air-bourne! That tissue just contains the stuff that your nose was able to filter. The rest is in your lungs. Gross, eh? Also not super healthy.
So, wait! What’s this about an exoskeleton?!
I used 1×2’s to wrap my box in all the right places so it accepts a furnace filter. It sucks in dirty, sawdust-filled air, and shoots it out into a furnace filter. Cleaning the air, and maybe even saving my lungs.
