3D printer air filtration with HEPA and activated carbon.
This is a combination activated carbon and HEPA filter for 3D printing. It uses 75x30mm fans (either one or two) to draw air through a wall of activated carbon pellets and then through a HEPA filter.
The filter can be printed with one fan for filtration only, or with a second fan to provide chamber exhaust or additional airflow.
A method of mounting the filter to 2020 extrusions is coming soon.
Documentation is available.
