Hepa Filter Holder for BVMs

thingiverse

This is a HEPA filter holder for BVMs. I created this filter holder because there was a shortage of commercial products available. The filters were 1.25 inch square, made from HEPA-rated vacuum cleaner bags that captured "HEPA Media Traps 99.97% of Particles Down to 0.3 Microns." A storage box for replacement HEPA filters is also included. I used 75% infill because the holders would be used by ambulance teams. I chose PETG because it offers water and chemical resistance. Some samples were soaked in 70% alcohol and others in 25% bleach without showing any visual effects. Printing settings were: Nozzle at 260C, bed temperature at 70C, flow rate at 60%, and cooling at 50%. Please note that I do not have the knowledge or equipment to verify the level of protection this filter holder provides. It is up to the user to determine the actual level of protection and use it accordingly.
