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

Though cloth masks provide only minimal protection in opposition to the spread of COVID-19 and different viruses, the Centers for Illness Control and Prevention (CDC) now recommend that everyone use them when leaving the house. The hope is that this low-risk, comparatively straightforward intervention can make a dent within the spread of COVID-19 by people with no symptoms or extraordinarily delicate ones.

However masks aren’t exactly easy to come back by: Medical-grade ones are already briefly provide 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 recommendations, even non-medical fabric masks are sold out or backordered in many on-line stores. In case you’re attempting to determine if and how you should cover your face in your next essential trip out of the house—for a walk on an uncrowded road or to buy needed groceries, as an example—right here’s a guide to all your options.

Things to search for and keep away from when shopping for a cloth masks

A number of crafters and makers, as well as companies that often sell other fabric products, are now offering non-medical masks for sale. But not all of those masks are created equal. In the event you’re ordering protective equipment online, right here’s what to look for:

Don’t buy medical-grade, filtering masks unless you’re 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 masks ought to cover your nostril and mouth and may have fastenings that preserve it firmly in place while you talk, move, and breathe. If you need to contact your face to adjust your masks, you risk exposing your nostril or mouth to germs.

Ideally, the masks should have some sort 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 following finest thing, and your mask should have a minimum of layers of it.

Your mask ought to be straightforward to sanitize by boiling or throwing within the washing machine. Which means it shouldn’t have fabric glues, delicate materials, or funky decorations (aside from prints on the fabric). Elaborations like sequins (yes, there are individuals selling sequined masks right now) provide surfaces that viral particles can linger on for days.

In case you buy a fashionable cover to go over your mask—some stores are selling glittery material covers and chainmail overlays, for example—remember that this outer layer is being exposed to viral particles. You could 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 different warm-weather gear designed to cover your nostril and mouth are unlikely to be suitable for stopping the spread of COVID-19. Because they’re designed to be as easy to breath by way of as possible, they tend to be made of loose fabrics.

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

Jersey fabrics, towels, and any textiles that stretch while you pull them are possible too loose, she says, as are most sweaters and different knit yarns. So if you really can’t sew or put collectively a mask with hair ties as described below, covering your nostril and mouth with a bandana tied round your face is probably slightly more efficient and simpler to sanitize than a balaclava or wound-up scarf. But all of those workarounds are mostly only beneficial in that they remind you to not contact your face and shield bystanders from the worst of your coughing and sneezing. For those who’re coughing and sneezing, you should really be staying inside.
