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

April 24, 2020 business

Although material masks provide only minimal protection towards the spread of COVID-19 and different viruses, the Centers for Disease Control and Prevention (CDC) now advocate that everyone use them when leaving the house. The hope is that this low-risk, comparatively simple intervention could make a dent in the spread of COVID-19 by folks with no signs or extremely mild ones.

But masks aren’t exactly simple to come back by: Medical-grade ones are already in brief provide for healthcare workers who need them, so healthy individuals shouldn’t even try to purchase them. And within the wake of the CDC’s new suggestions, even non-medical material masks are sold out or backordered in lots of online stores. In the event you’re trying to determine if and how you need to cover your face in your next essential journey out of the house—for a stroll on an uncrowded avenue or to purchase vital groceries, as an illustration—here’s a guide to all your options.

Things to search for and keep away from when buying a material mask

Lots of crafters and makers, as well as corporations that usually sell different fabric products, are now providing non-medical masks for sale. But not all of those masks are created equal. If you’re ordering protective equipment online, here’s what to look for:

Don’t buy medical-grade, filtering masks unless you are immunocompromised or are caring for someone sick with COVID-19. Hospitals are experiencing extreme shortages of those masks, and they don’t seem to be shown to provide significant protection for healthy individuals.

Your masks ought to cover your nostril and mouth and should have fastenings that keep it firmly in place while you speak, move, and breathe. If it’s important to touch your face to adjust your mask, you risk exposing your nostril or mouth to germs.

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

The most effective materials are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the next greatest thing, and your masks ought to have at the least layers of it.

Your masks needs to be simple to sanitize by boiling or throwing in the washing machine. That means it shouldn’t have fabric glues, delicate supplies, or funky decorations (aside from prints on the fabric). Gildings like sequins (yes, there are folks 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 masks—some stores are selling glittery fabric covers and chainmail overlays, for example—do not forget that this outer layer is being exposed to viral particles. You need to remove it and sanitize it just like you would with the masks itself.

What about a balaclava or scarf?

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

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

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