Under $100.00! I got this fan from Northern tools and the filters from Walmart. Just built a box around it and for the slots and the hole for the fan I used my CNC. But even without the CNC it was simple. I need simple. the filtering surface is 40×30. It is hard to believe what I have been breathing. This filter catches a lot of dust. It cycles more air than one of the store bought ones. Just wanted to share uncase someone else wanted to biuld one.
