"CEG Extreme" COVID19 Mask Frame for Halyard H600

This design has been tested and is suitable for community use, but at this time does not meet the full requirements for use in a clinical setting.

I really like this design it seems that an idea like this would be very close to a widely held solution for many people.  I wonder if that material is a bit too expensive though.  I cannot get the material through amazon, 24 inch square sheet is like 60 dollars for five.  To me that is expensive if you want to protect your family for months on end.  

Hey everyone,

I work in healthcare, specifically where Halyard H600 and other similar materials are used.  This material is used to wrap instrument trays that are to be sterilized in an autoclaves for surgery.  It is not only readily available at every surgery center, or hospital, but they throw it away in droves!  I mean, hundreds of pounds of this H600 per day at larger institutions are just tossed into dumpsters. Very frequently, it is used to wrap a tray, and never actually brought into surgery so it's still clean.  It is very resilient, and can be sterilized or cleaned by simply placing it in your own oven.  This material is used in autoclaves at hundreds of degrees under extreme pressure.  

I'm going to connect with a sterilization processing department head to start gathering the unused H600 for distribution to healthcare workers in need.

If you can't access the original material, consider using two layers of blue shop towels. Some have tested at 93% filtration down to 0.3 microns. Search business insider face mask tests

Thanks for your comment. You can alternatively use 2 layers  of 3M Filtrete 1500 or 2200 filters that you dissassemble, 2 layers of blue shop towels, or other alternative materials for community use.

If you cannot access the fabric available medical professionals, consider blue shop towels. Two layers provide excellent filtration. Business insider published an article that tested filtration of mask materials.

Has there been any updates to the test results, in particular the sub-micron particle filtration of the H600 material?
