Medical Mask

Introduction: Medical Mask

These masks can go directly to the hospitals. Until the government catches up with the demand many of our nurses assistants across the nation are going without masks all together. Nurses and doctors that are lucky enough to be provided masks are given one to keep. One. the N 95 mask are meant to be disposed of after use. and they are not easily sanitized as the material they are made out of breaks down when wet .There’s an outpouring across the nation of nurses asking us to make masks. These masks \ can be run with bleach through the washer and reused.

Our local healthcare worker warriors on the front lines are risking their lives right now and the lives of their loved ones going to the hotspot to get us through this.

Supplies

  • Filter Fabric or other cloth
  • Wire
  • Sewing supplies
  • Electrical Tape

Step 1: Cut Fabric

I used an appetizer plate and an business card as a template.

Step 2: Sandwich the Filter

Cut 2 peices of the sew through cotton you have and one piece of HEPA vacuum bag, household air filter cartridge, or non-woven sewing interfacing. If you don't have anything tea towel type material will work

Pin it

Step 3: Sew

Sew A quarter inch seam allowance leaving a 2 inch gap, and then sew a circle 5/8s inch inside of that all the way

Step 4: Insert Wire

Take 14 inches or so of wire with a rubber casing that will keep shape if bent And push it between the two seems.

Twist together and tape them tightly with electrical tape

Step 5: Sew

Finish the outer seam

Step 6: Even Out

Now It should look like this even out the raffles as best you can

Step 7: Straps/Ties

I used binding so it can be tied but at this point, but if you have elastic you could sew it to the end of that stick out. If you use binding essentially a long 2 inch wide strip of fabric that is folded so over the raffles but not the wire

Step 8: Use

Now it should look something like this the wire will allow it to conform to the users face

    Question 1 year ago on Step 6

    Was the wire you used solid or braided? Was it copper (likely) or aluminum? Do you know what gauge wire it is? You refer to the jacket being "rubber" but was probably something else (e.g. THHN). Was it imprinted? The imprinting may look like nonsense, but it identifies the gauge and type of conductor and the jacket used. Finally... are you sending this through a washing machine?

    Question 1 year ago

    Do the materials you listed have the right micron filtration to work as a medical mask? Interesting tutorial all the same.

    Interfacing is what’s used in this tutorial it’s almost identical to the barriers in Surgical masks and it manufactured as a non woven like n95 not as good as course as is there is no available information on particle Flow thru interfacing but it is is definitely better then just cotton. It can stand up to being washed and bleached unlike merv 13 and higher vent filters. Something is better then nothing. And this is better then the plain cotton masks being made by many as it conforms to the users face and has an extra barrier. Cotton are 65 percent particle barriers so this is somewhere between 65 and 95 percent. Below is a pic of a surgical mask material next to rayon interfacing

    Ah thanks, and yes I agree something is better than nothing. Expecially for sick people who might have to travel, so they don't spread as much. Thanks!

    Great idea, nice design.
    Masks don't need to filter out individual virions, as they desiccate and inactivate once their snot droplet evaporates. Purpose of the masks is to filter out the droplets. Remember the more "effective" the filter, the work of breathing increases, to the point where you rip of the mask and gulp for air. So it's always a trade-off. Commercial N95s can indeed be gently handwashed with a little dish soap and water, and air dried overnight. I use a small spray bottle and spritz mine with denatured alcohol after each shift.
