__FORCETOC__
==Prototype==
[[File:MVR_Assembly.png|thumb]]

==Design Questions==
*How will restricting the airflow as the virus reduce the function of the lungs.
*How much air flow is required?
**what is the volume, speed, pressure and duration of normal breathing?
**what is the volume, speed, pressure and duration of a Cough?
**what is the volume, speed, pressure and duration of a Sneeze?
How with the "extra air volume in the mask (re-breathing what you exhausted) affect "oxygen transfer in the lungs?
*What are the design criteria of approve masks?
*What are the filtering capabilities (limitations) of the HEPA filter material.
**What criteria are we looking for?
**What are the tradeoffs?
*What are the different face sizes configurations.  How many sizes will be needed?
*How to measure, evaluate leakage.

==Create==
Moulds can be made my anyone with CNC, 3D printer.
Machine shops can make moulds.
Can vacuum forming industry make these?
Can HEPA filter people make filters to size?
