Respirator for HEPA Filter Material by ShuttleSpace

Last crawled date: 4 years ago

My own design after looking 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.
Will need the silicone cooking sheet or a bathing cap to create the face seal. Maybe even an inner tube if the situation is desperate.
The top of the line 3M Filtrete furnace filters capture viruses, this material can be cut into disks and fitted to the intake. There are also other HEPA filters for air cleaners that could be adapted. Need to see which popular models are widely available
I didn't do any exhale ports yet.

All hospitals should have 3D printers now and I'm sure there will be special clips or devices that can be 3D printed to help the heroic hospital workers.
Here's the template/model for the flexible face seal that inserts into the slot.https://www.thingiverse.com/thing:4233120
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/ It addresses the respirators and their ability to protect the wearer. My design here relies on the user having a bit of technical ability to assemble and test the mask. The silicone from the baking sheet should make a good gasket. It can be cut to suit the different face shapes.
As for the filter material, the N95 material catches 95% so even that is a risk.
With my design here, the sky's the limit for whatever filter or filter material you want to use.
Watching the Italian news today, I saw a care giver wearing a simple dollar store dust mask, so she's almost certain to get sick now.
