Face Mask Pattern from Hospital Facility-be safe

They have lots of the large ponytail ties in the picture at the grocery misc hair isle as of 3-29-2020-  They come 24 in a package so -12 masks per package... I got 4... so I am going back today with masks donation to them and get some more.

Here is the link for Youtube video instruction and pdf pattern for this style filtered mask... you can use ponytail ties or read microbiologist notation under the video

Couple of extra tips from a PhD Microbiologist (pathogen and air quality experience) and avid sewist. You can use fine men’s shirting or high thread count sheets for fabric. You can use a third layer of cotton fabric in center if you can’t access HEPA quality fabric. Also you could use a non woven interfacing for that interior layer. The idea is that the three layers of woven fabric are offset from one another causing air when it migrates in or droplets when they migrate out to not have a straight path. If you use non woven interfacing even better because it is a complex matrix. The entering particulates collide so to speak with the fibers and are captured. Also you can consider a synthetic fabric for the middle layer since many polyesters and nylon are charged and can better capture charged cells. Instead of the pony holders I’ve used fold over elastic about 28 inches long to bind each short side of the mask. This leaves stretchy tails for tying (makes it easier to fit) as you just zig zag across folded over elastic from one end to the other. Many have also used garbage bag wires and plastic floral stems for the nose piece, you can sandwich it in duct tape so it stays waterproof. I suggest inserting it into a 4” casing made with fold over elastic sewn to the lining side of the mask. This way you can reinsert new wire as needed. Lastly after you turn it consider top stitching around to increase durability. Good work guys!
