The file 'Creality K1 Max Carbon Hepa Filter 3D Printer Model' is (FCStd,step,stl) file type, size is 1.7MB.
I wanted to add a hepa filter for my K1 max, while keeping the original Carbon filter. I had some extra hepa filters from my Roborock S5 max vacuum cleaner so I used two of them to reduce the static pressure.
Print this, put the carbon filter first, then the two hepa fiters. Use a bit of teflon tape around the part that goes in the printer to reduce vibration noise and get a better fit.
It really works well! no more smells with ASA/ABS prints. You should run the fan at 100% to counter the increased static pressure, but the noise partially blocked by the filters so overall it is not too bad noise wise.
I uploaded the STEP file, the STL file and my messy FREECAD file.
Enjoy!
