Hepa Filter Holder for BVMs

pinshape

This is a HEPA filter holder for BVMs. Designed with urgency, this filter holder was created due to a critical shortage of commercial products available on the market. The filters used are 1.25 inch square and sourced from HEPA rated vacuum cleaner bags that boast an impressive rating: "HEPA Media Traps 99.97% of Particles Down to 0.3 Microns". Additional to the filter holder is a compact storage box designed specifically for replacement HEPA filters. To ensure maximum durability, I employed a 75% infill rate and chose PETG as the primary material due to its exceptional water and chemical resistance properties. A series of rigorous tests was conducted to further validate these claims: some samples were submerged in 70% alcohol, while others were exposed to 25% bleach - neither showed any signs of compromise. Printing parameters included a nozzle temperature of 260C, a bed temperature of 70C, a flow rate of 60%, and cooling at 50%. Please note that I lack the knowledge and equipment necessary to verify the level of protection provided by this filter holder. It is therefore essential for users to assess the actual level of protection it offers and utilize it accordingly.
