Desktop Air Filter

I designed this air filter to put in my daughter's room to help filter out allergens. It uses a shop-vac HEPA filter and a 140mm pc fan. You'll also need a 12v power supply if your fan doesn't come with one. Assembly is simple. The top and bottom caps plug into the filter, the fan screws to the top cap, and the fan shroud clips over-top of the fan. The decorative grill is optional to hide the filter.
