OS Respirator Version 1

A unique prototype respirator, that utilizes swap-able filters, with a theoretically longer (or easier maintained) lifespan than cloth masks.

Disclaimer: Like cloth masks, the OS Respirator is not intended to replace the CDC recommended N95 respirators [1]; however, the OS Respirator is designed to provide protection that is sufficient in the absence of something similar to an N95.

100% Cotton T-shirt
Pillowcase
Linen
Silk
Tea Towel
