A guide to purchasing (or making) a face mask for COVID-19

April 23, 2020 business

Although cloth masks provide only minimal protection in opposition to the spread of COVID-19 and other viruses, the Centers for Illness Management and Prevention (CDC) now suggest that everybody use them when leaving the house. The hope is that this low-risk, comparatively simple intervention can make a dent in the spread of COVID-19 by folks with no signs or extremely delicate ones.

However masks aren’t precisely straightforward to come back by: Medical-grade ones are already briefly supply for healthcare workers who need them, so healthy folks shouldn’t even try to purchase them. And within the wake of the CDC’s new suggestions, even non-medical fabric masks are sold out or backordered in many online stores. Should you’re trying to determine if and the way you should cover your face on your next essential journey out of the house—for a walk on an uncrowded street or to purchase essential groceries, as an illustration—here’s a guide to all your options.

Things to search for and avoid when buying a fabric masks

Numerous crafters and makers, as well as firms that usually sell different cloth products, are actually providing non-medical masks for sale. However not all of these masks are created equal. In the event you’re ordering protective equipment on-line, right here’s what to look for:

Do not buy medical-grade, filtering masks unless you might be immunocompromised or are caring for somebody sick with COVID-19. Hospitals are experiencing extreme shortages of those masks, and they are not shown to provide significant protection for healthy individuals.

Your mask should cover your nose and mouth and may have fastenings that preserve it firmly in place while you speak, move, and breathe. If it’s a must to contact your face to adjust your mask, you risk exposing your nose or mouth to germs.

Ideally, the mask should have some form of adjustable band to minimize gaps between your nose and your cheeks.

The simplest fabrics are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the next best thing, and your mask should have at least two layers of it.

Your masks should be easy to sanitize by boiling or throwing in the washing machine. Which means it shouldn’t have fabric glues, delicate supplies, or funky decorations (other than prints on the material). Embellishments like sequins (sure, there are people selling sequined masks right now) provide surfaces that viral particles can linger on for days.

If you happen to purchase a fashionable cover to go over your mask—some stores are selling glittery cloth covers and chainmail overlays, for example—keep in mind that this outer layer is being uncovered to viral particles. You need to remove it and sanitize it just like you would with the mask itself.

What a few balaclava or scarf?

Rachel Noble, a public health microbiologist at UNC at Chapel Hill, tells PopSci that balaclavas and other warm-climate gear designed to cover your nose and mouth are unlikely to be suitable for stopping the spread of COVID-19. Because they’re designed to be as easy to breath via as attainable, they tend to be made of loose fabrics.

“You need to select a really, really tightly woven fabric,” Noble says. “We’re speaking about something that’s approximately the density of the weave of a bandana, or a really high-high quality bedsheet.”

Jersey materials, towels, and any textiles that stretch once you pull them are probably too loose, she says, as are most sweaters and different knit yarns. So when you really can’t sew or put together a mask with hair ties as described below, covering your nose and mouth with a bandana tied around your face is probably slightly more effective and easier to sanitize than a balaclava or wound-up scarf. But all of those workarounds are largely only beneficial in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. Should you’re coughing and sneezing, you should really be staying inside.
