I have the Glowforge Air Filter, mostly for the acrylic I cut, but I wanted the option to vent out a nearby window for less harmful materials and stuff that’ll clog the filter quickly, like draftboard.
I think I’ve created a pretty solid setup for selecting between the window and the filter and thought I would share—and solicit feedback if you think I’m making a grave aerodynamic error!
More clamps, y-fittings, and blast gates than I needed (but cheaper than buying separately): https://www.amazon.com/POWERTEC-70201-4-Inch-Three-Machine-Collection/dp/B01N21P1WE
Probably could have gotten a cheaper hose but this one is pretty sturdy: https://www.amazon.com/gp/product/B00SJRDHUQ/
Oh and I decided to try this as a pre-filter; others have linked similar products but this one is the perfect size if you cut it in half: https://www.amazon.com/gp/product/B07JZ3QBX9/
I have a blast gate for each exhaust so one doesn’t try to blow into / suck from the other. I tried to keep angles to a minimum. I can also seal the window gate so critters don’t try to get in.
Let me know what you think!
