A Mask is One Piece of the Puzzle

Remember that a mask, while important, is just one component when it comes to reducing the spread. It’s most important to stay at home, keep your distance, and wear a mask if you need to go out near other people (like at a store).

  1. Stay In Place (at home)
  2. Keep your Distance (6 feet or more)
  3. Cover Your Face (with a non-pro mask)

The Science Behind Using Masks

These articles outline why DIY masks are important to help curb the spread of COVID-19. It’s wise to wear a DIY mask when out in public places where people are close together, like grocery stores, as the virus spreads through the air when people talk and via asymptomatic people (those who may not even know they have it).

Mask Handling Precautions

It’s extremely important to handle the mask correctly, especially during and after use, as the mask may have virus particles on it.

  • During Use: Don’t touch or fiddle with the mask (remember, don’t touch your face or the contaminated mask!)
  • After Use: Carefully remove the mask by the straps, being sure not to touch the front of the mask, which may be contaminated. If you don’t have a safe place to hold the mask while out, wait until you get home to remove it (or toss in a container/bag). Then discard the removable filter, clean your hands with hand sanitizer and drop the mask in water with soap and hand wash.

    Tip: take along a washable Tupperware container to place your mask in after use. Wash both the mask (without filter) and container when home.

Making Your Own Mask – Common Design Themes

The articles and videos below share some common themes:

  • Ideally use two layers of pre-washed materials (e.g. tightly woven cotton t-shirts or pillowcases) with a removable insert (e.g. paper towel, coffee filter, etc.) to allow for washing.
  • Wash fabric materials first to ensure they don’t shrink in later washes.
  • Ensure a tight fit around the edges of your face and nose (use nose wire, ideally)
  • Hand wash the mask with soapy water after use and dry.

Materials for Mask

It’s generally considered best to have two layers of pre-washed, tightly-woven fabric (high thread count cotton such as 600 thread count pillowcases, kitchen towel, denim), with a removable filter insert in between (such as a paper towel).

For the fabric, hold it up to a bright light. “If light passes really easily through the fibers and you can almost see the fibers, it’s not a good fabric.” According to a 2013 study, tea towels, antimicrobial pillowcases, and cotton-blend fabrics were found to be more effective at filtering out small particles than 100 percent cotton T-shirt fabric, a scarf, and silk (see chart in this article).

In addition, you may have different materials layers for the mask. For example, the material that sits directly against your mouth should be comfortable, washable tightly knit fabric, ideally made out of something that wicks moisture such as a polyester, nylon, or a spandex-cotton blend, like athletic clothes often have.

NOTE: Most scarves and bandannas are NOT good materials as they are too porous.
