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

Although fabric 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 everyone use them when leaving the house. The hope is that this low-risk, relatively easy intervention can make a dent within the spread of COVID-19 by people with no signs or extremely mild ones.

But masks aren’t precisely simple to come back by: Medical-grade ones are already in brief provide for healthcare workers who want them, so healthy folks shouldn’t even attempt to buy them. And in the wake of the CDC’s new recommendations, even non-medical fabric masks are sold out or backordered in lots of online stores. Should you’re attempting to determine if and the way you need to cover your face on your subsequent essential trip out of the house—for a walk on an uncrowded avenue or to buy necessary groceries, as an illustration—right here’s a guide to all your options.

Things to look for and avoid when buying a material mask

A number of crafters and makers, as well as firms that normally sell different material products, are now providing non-medical masks for sale. But not all of these masks are created equal. For those who’re ordering protective equipment online, here’s what to look 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 those masks, and they are not shown to provide significant protection for healthy individuals.

Your mask should cover your nostril and mouth and should have fastenings that preserve it firmly in place while you talk, 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 masks ought to have some kind of adjustable band to minimize gaps between your nose and your cheeks.

The best materials are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the subsequent finest thing, and your mask ought to have no less than two layers of it.

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

In the event you buy a fashionable cover to go over your masks—some stores are selling glittery cloth covers and chainmail overlays, for instance—do not forget that this outer layer is being uncovered to viral particles. You need to remove it and sanitize it just such as you would with the masks 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-climate 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 simple to breath by way of as doable, they are typically made of loose fabrics.

«You need 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 probably too loose, she says, as are most sweaters and other knit yarns. So in case you really can’t sew or put together a mask with hair ties as described beneath, covering your nostril 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. However all of those workarounds are mostly only helpful in that they remind you not to contact your face and shield bystanders from the worst of your coughing and sneezing. In case you’re coughing and sneezing, you must really be staying inside.
