Stackable Hepa

This is a TinkerCad Remix of the BentoBox V2 Hepa box and Lid. Which makes the Hepa box movable (Hepa under carbon filter). While I was at it, I created an additional Lid that should allow more air flow.

I purchased a BentoBox from Voxel (Voxel PLA & PETG are great to use). If this was an option when I purchased from Voxel (voxelpla.com) I would have chosen it.

After assembling I noticed that the air draw goes through the Hepa Filter first and then through the Carbon.

I have several manufactured air purification systems, and this is backwards to how they work. They pull through the carbon and then through the Hepa! I did some research and found only 1 manufacture that has this pulling Hepa then through carbon.

Asking an AI for clarification: "carbon should come before HEPA in an air purifier filter system. A carbon pre-filter catches large particles before they reach the HEPA filter, which can extend the life of the HEPA filter. The HEPA filter then captures the microscopic particles that pass through the carbon filter. The carbon filter traps chemicals and odors that might damage the HEPA filter, while the HEPA filter catches any remaining particles. Carbon filters are also good for removing odors and VOC gasses, but they can pollute your air with carbon dust. Using a HEPA filter after the carbon filter will remove any carbon dust."

In the case of 3d printing I really would rather have the Hepa filter catch the carbon (even though I may have to replace it more often). Having the carbon dust pushed into my printers, bearings, rods etc. didn’t seem helpful.
