HEPA_Filter_Canister

I needed to build an enclosure for my printer to scrub the air clean of nano particles. This thing fits snug into a 3" bore from a hole saw. It holds a small HEPA filter and activated charcoal filter. Uses 4 M4 bolts to hold the top and bottom together.

Print both flat for no supports.

Enviro Care for Kenmore EF-2 canister replacement. Order off amazon. The charcoal filter is cut to size foam filter.

I used an 80MM 23 cfm fan to perform the air changes within the enclosure.
