SLORespirator
We have modified the Billings Respirator model to include a larger filtration area, revised chin seal, thinner walls to allow heat-molding to a user's face, and added a cap similar to the LowellMakes mask to allow the entire mask to be sanitized between patients. This provides a safe, effective, and locally producable way to markedly extend the supply of n95 masks.
We have achieved subjective n95 fit testing on a wide variety of people and would like this model approved for clinical use. We feel that as this device is essentially a holder for NIOSH-approved n95 material and therefore should be considered an extension of already approved equipment rather than an entirely new device. Thank you!
These print well if to be face-down on the bed without support material. We had some issues with the filter insert and bed adhesion, which was fixed with a 2 line brim.
