The Midwest Mask is a variation on the Deaconess design by Deaconess Hospital in Evansville, IN. We chose to modify the pattern with an emphasis on the ability to be sterilized and re-used as needed. To accomplish this, we suggest cloth ties as opposed to elastic.
The design and assembly are straightforward and can be made using readily available materials: 100% tightly woven cotton or NWPP (non-woven polypropylene), which is used in surgical grade masks and reusable shopping bags. OLY*fun fabric is a good NWPP fabric with the same density as that used in surgical masks (25 gsm).
The mask is able to withstand the high temperatures of being boiled or autoclaved in order to be fully sterilized.
Please include the printed form found under Packaging Instructions with each mask.
These masks are purely meant as a way to reduce the spread of airborne pathogens and is not guaranteed or rated in any way to prevent infection.

You can make this pattern using entirely cotton fabric, entirely NWPP (non-woven polypropylene, such as OLY*FUN or that used in reusable shopping bags), or a mix of both.
Main Fabric: cut 2 rectangles: 6” by 9”
100% cotton (prewashed and dried for shrinkage) OR NWPP
Strap Fabric: 4 straps, each 16"-18" in length
100% cotton sewn using the instructions below OR use 100% cotton twill tape OR bias tape OR use NWPP folded in half and sewn down the side.
If you are using twill tape, skip this step. If you are using NWPP for the straps, do not iron! Just cut a 1/2"-1" wide strip, fold in half, and sew it down the side. NWPP does not fray at the edges like cotton. If you are using bias tape, just sew it closed up the side as well.
Cut 2” wide strips of fabric for the straps . Cut them as long as possible; you can shorten them later.
If you are familiar with making bias tape, this is the same process, with the only notable difference being that your strips do not need to be cut on the bias. Fold the long edges of the strap inward towards the middle, creating a windowpane fold. Iron down.
Fold in half again along the center and iron.
Sew along the edge to secure the fold.
Cut to 16”-18” in length. 
sewing machine required, pins optional
Stack the two 6” by 9” rectangles right sides together. 
Sew along the top starting about 2” from the corner. Insert the end of one strap in the corner and sew in place. As long as it’s secured, you’re good. We’re looking for efficiency and effectiveness, not beauty.
Continue sewing along the edge, inserting straps into each corner. All straps should be in between the two rectangles (like a pillow). Stop sewing when you have about a 2” wide gap left at the top.
Turn the mask right side out. Sew up the little gap that’s left open.
Form three pleats on each edge and pin in place.  It doesn’t matter if they go up or down, but both sides must go the same way.
Sew (topstitch) around the whole mask once more to secure pleats and seal.
Once assembled, please do a final wash and dry cycle on high heat to begin the sterilization process.
Print and fill this form to include with each mask (6 per page).
Once done, immediately put each mask into its own ziplock bag with a filled out information sheet and set aside for drop-off. This will keep the mask as clean and germ-free as possible during transportation and delivery to the end user.

 NWPP is the fabric I prefer, but cotton is much more abundantly found. Surgical masks are made from NWPP that is the same density as OLY*fun (25 gsm), and are shown to be much more effective at filtration. As for cotton, two layers appears to be the ideal amount as shown by some research studies conducted by Cambridge University in 2009. As for the NWPP, I cannot find evidence that suggests increasing the number of layers past two has any discernable effect on filtration or waterproofing, but rather makes breathing more difficult and sewing the pleats is a nightmare and a half. If you have found evidence to the contrary, please contact me (firstname.lastname@example.org)!
 A rotary cutter is helpful here. Also helpful to note that cotton will rip along the weave in a straight line—simply measure and make small cuts and rip away.
 Ideally, 18”, but optimize the usage of your scrap cotton.
 NWPP doesn’t have sides but cotton does.
 Alternatively, you can form the pleats as you sew.
Most patterns suggest sewing straps from elastic for DIY face masks. While I absolutely agree that elastic is more comfortable and easier to sew than the cotton straps, it's not quite as hardy when it comes to sterilization, and right now it's very hard to source! If you have elastic you would like to use, please make sure it's latex free (sometimes hard to tell), and know that it may not be able to be reused. Thanks!
