Like many of you, I’ve looked at the Trend and Triton powered air masks. And like many of you, I decided to make do without one because they are fairly pricey.
Well, today in my travels I found a link from a steampunk site (yes, my old hp laptop is going to become wood-clad and steam driven very soon) for a DIY powered mask.
This is another Jake Von Slatt project. He used a car air filter, though I think I am going to use a cabin air filter since almost all of them are HEPA rated now.
-- Made lots of sawdust and pounded some nails. Haven't finished anything, though.
