To address the shortage of respiratory PPE, Tetra Bio Distributed (TBD) created a half-facepiece powered air purifying respirator (PAPR) named PAPRa. We designed and iterated upon 3D printed models and custom electronics to create a PAPR which meets N95 fit standards yet could be built using resources common in the US maker community. We are now focused on manufacturing a NIOSH regulatory compliant device while maintaining open source designs and licensing, a balance that, to our knowledge, has not been achieved in the powered respirator space.
