Respirator for HEPA Filter Material

thingiverse

My own design after taking a close look at what's available in most building supply stores. The straps should attach to the body or thread through all the eyes as one piece. A silicone cooking sheet or bathing cap will be needed to create the face seal, and if necessary, an inner tube can be used. Top-of-the-line 3M Filtrete furnace filters capture viruses; this material can be cut into disks and fitted to the intake. Other HEPA filters for air cleaners could also be adapted, depending on which popular models are widely available. Exhale ports have not yet been done. Edits, contributions, and comments are always welcome. A group has been created at 3dorchard.com and thingiverse.com to share designs and ideas for fighting the virus. All hospitals should now have access to 3D printers, which will allow them to create special clips or devices to aid heroic hospital workers. Here's a template/model for the flexible face seal that inserts into the slot: https://www.thingiverse.com/thing:4233120 A new reed valve has also been created and can be found here: https://www.thingiverse.com/thing:4296315 Dan from Orchard sent me this link about printing medical parts: https://blog.prusaprinters.org/from-design-to-mass-3d-printing-of-medical-shields-in-three-days/. This article addresses respirators and their ability to protect the wearer, which is similar to my design. However, it relies on users having some technical skills to assemble and test the mask. The silicone from a baking sheet can be used to create a good seal, and it can be cut to fit different face shapes. As for filters, even the N95 material only catches 95% of particles, so there's still a risk involved. But with my design, users have the freedom to choose whatever filter or filter material they want to use. Watching Italian news today, I saw a caregiver wearing a simple dollar store dust mask, which makes her nearly certain to get sick now.
