Reusable facial mask frame filter

Hello, I've reworked the design to accommodate various filters. The seal and nasal accommodation have been significantly improved, so I believe you could utilize a rigid plastic like PLA. It's about placing the filters on the outside in the cavity visible from the outside and closing them with caps that are secured by tightening. Once printed, the mask simply needs filing of its surfaces and gluing neoprene adhesive or EVA rubber for sealing. This design is quite robust and can be reused since it's disinfectable between uses; all you need to discard is the filters. The design is almost watertight, making breathing easy. You can use makeup remover discs as filters. I must point out that this design isn't certified, and I cannot guarantee its effectiveness against coronaviruses. However, I believe it offers a good level of protection that could reduce the risk of contagion.
