Making PPE Amidst SARS-CoV-2 Part I
Update: see our new mask design here.
We're facing a crisis right now and we're unfortunately ill-prepared to respond.
That's why we have joined the effort to develop an effective mask that can be made locally.
This is our first take and we're looking for feedback from medical professionals.
Our goals in this design were:
- Make a highly effective mask
- Make it easy and quick for others to make
- Make it reasonably comfortable
- Use the least number of custom parts
- Use the widest variety of off the shelf parts
Key features of the mask are:
- it prints in under 3 hours and has 1 printed part
- nose cone features common filter material like air filters or vacuum bags
- hose clamp is best but can also use zip-ties or rubber bands
- foam liner makes it comfortable
- filter material fits over nose cone
- held down by hose clamp (makes it easy to swap)
- we're experimenting with putting the filter inside and making it easier to swap
- foam liner hot glued in for comfort
- we used an FDA approved silicone foam we had lying around - we realize most folks won't have that. Almost any foam will do.
