A guide to purchasing (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 other viruses, the Centers for Disease Control and Prevention (CDC) now advocate that everybody use them when leaving the house. The hope is that this low-risk, relatively simple intervention could make a dent in the spread of COVID-19 by people with no symptoms or extremely delicate ones.

But masks aren’t exactly easy to come back by: Medical-grade ones are already in brief supply for healthcare workers who want them, so healthy individuals shouldn’t even attempt to purchase them. And in the wake of the CDC’s new suggestions, even non-medical fabric masks are sold out or backordered in lots of on-line stores. If you happen to’re trying to determine if and the way it’s best to cover your face in your next essential trip out of the house—for a stroll on an uncrowded avenue or to purchase crucial groceries, for example—here’s a guide to all your options.

Things to search for and avoid when buying a material mask

Plenty of crafters and makers, as well as corporations that often sell other cloth products, are now offering non-medical masks for sale. However not all of those masks are created equal. When you’re ordering protective equipment online, right here’s what to search for:

Do not purchase medical-grade, filtering masks unless you’re immunocompromised or are caring for somebody sick with COVID-19. Hospitals are experiencing excessive shortages of these masks, and they are not shown to provide significant protection for healthy individuals.

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

Ideally, the masks should have some type of adjustable band to reduce gaps between your nostril and your cheeks.

The most effective materials are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following greatest thing, and your mask ought to have a minimum of 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 material glues, delicate materials, or funky decorations (aside from prints on the fabric). Embellishments like sequins (sure, there are people selling sequined masks right now) provide surfaces that viral particles can linger on for days.

When you purchase a fashionable cover to go over your mask—some stores are selling glittery cloth covers and chainmail overlays, for instance—remember that this outer layer is being exposed to viral particles. You must remove it and sanitize it just such as 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-climate 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 straightforward to breath by as potential, they are typically made of loose fabrics.

“You wish 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 fabrics, towels, and any textiles that stretch once you pull them are possible too loose, she says, as are most sweaters and different knit yarns. So in the event you really can’t sew or put collectively a mask with hair ties as described below, covering your nose and mouth with a bandana tied round your face is probably slightly more effective and simpler to sanitize than a balaclava or wound-up scarf. But all of these workarounds are principally only useful in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. If you’re coughing and sneezing, you should really be staying inside.
