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

Although fabric masks provide only minimal protection against the spread of COVID-19 and other viruses, the Centers for Disease Control and Prevention (CDC) now suggest that everyone use them when leaving the house. The hope is that this low-risk, relatively simple intervention can make a dent in the spread of COVID-19 by folks with no signs or extraordinarily delicate ones.

However masks aren’t precisely straightforward to come back by: Medical-grade ones are already in short provide for healthcare workers who want them, so healthy individuals shouldn’t even try to buy them. And in the wake of the CDC’s new recommendations, even non-medical cloth masks are sold out or backordered in lots of online stores. In the event you’re trying to determine if and the way it is best to cover your face in your subsequent essential journey out of the house—for a stroll on an uncrowded road or to buy mandatory groceries, for instance—right here’s a guide to all of your options.

Things to search for and keep away from when buying a cloth mask
A number of crafters and makers, as well as corporations that often sell different material products, are actually providing non-medical masks for sale. But not all of those masks are created equal. When you’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 extreme 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 keep it firmly in place while you speak, move, and breathe. If you need to touch your face to adjust your mask, you risk exposing your nostril or mouth to germs.
Ideally, the masks should have some sort of adjustable band to attenuate gaps between your nose and your cheeks.
The simplest materials are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the next best thing, and your masks ought to have at the least layers of it.
Your masks should be simple 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 material). Gildings like sequins (yes, there are people selling sequined masks proper now) provide surfaces that viral particles can linger on for days.
If you purchase a fashionable cover to go over your mask—some stores are selling glittery fabric covers and chainmail overlays, for instance—keep in mind 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 preventing 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 wish to choose 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 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 the event you really can’t sew or put together a masks with hair ties as described below, covering your nose and mouth with a bandana tied round your face is probably slightly more effective and easier to sanitize than a balaclava or wound-up scarf. However all of these workarounds are principally only helpful in that they remind you to not contact your face and shield bystanders from the worst of your coughing and sneezing. Should you’re coughing and sneezing, you need to really be staying inside.
