The Tetra Powered Air Purified Respirator can be strapped to a MOLLE backpack/belt/etc.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.

You should have assembled the Mask, Fan Box, and M12 Controller Box at this point.

A 3-row MOLLE attachment point would use the short adaptor, while longer attachments can use the longer adaptor.

You will need these components. Prices fluctuate, and so are not included here. Alternative versions can be sourced, and we welcome edits for tested alternatives.

These tools are recommended. URLs are for tools purchased and used in the building of the prototypes:

Once the PAPRa has been built, it should be worn. This guide provides a simple way to put components together in an over-the-shoulder configuration. The Fan Box has multiple attachment points, so other configurations are possible-- and please let us know if you come up with something you really like!

Cut the webbing into roughly 2 foot strips.

Weave the strap into the box base plate and the MOLLE adaptors:

Use triglides to hold the straps in place:

The m12 controller can also be strapped to the belt:

And now you have a Tetra PAPRa on a MOLLE belt for many hours of comfortable wearing!
