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 suggest that everyone use them when leaving the house. The hope is that this low-risk, relatively easy intervention can make a dent in the spread of COVID-19 by folks with no symptoms or extremely mild ones.
But masks aren’t exactly straightforward to return by: Medical-grade ones are already briefly provide for healthcare workers who need them, so healthy individuals shouldn’t even try to purchase them. And in the wake of the CDC’s new recommendations, even non-medical material masks are sold out or backordered in lots of online stores. In case you’re trying to determine if and the way you should cover your face on your subsequent essential journey out of the house—for a walk on an uncrowded avenue or to buy essential groceries, as an example—here’s a guide to all your options.
Things to search for and avoid when shopping for a material mask
Plenty of crafters and makers, as well as firms that often sell other fabric products, are now offering non-medical masks for sale. But not all of these masks are created equal. Should you’re ordering protective equipment online, here’s what to search for:
Don't buy medical-grade, filtering masks unless you're immunocompromised or are caring for someone sick with COVID-19. Hospitals are experiencing extreme shortages of those masks, and they aren't shown to provide significant protection for healthy individuals.
Your mask should cover your nostril and mouth and may have fastenings that maintain it firmly in place while you speak, move, and breathe. If you must contact your face to adjust your mask, you risk exposing your nose or mouth to germs.
Ideally, the masks ought to have some sort of adjustable band to minimize 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 next best thing, and your masks ought to have not less than two layers of it.
Your mask should be simple to sanitize by boiling or throwing within the washing machine. Meaning it shouldn’t have fabric glues, delicate supplies, or funky decorations (apart from prints on the material). Gildings like sequins (sure, there are individuals selling sequined masks right now) provide surfaces that viral particles can linger on for days.
For those who buy a fashionable cover to go over your masks—some stores are selling glittery cloth 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 masks itself.
What about a 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 nose 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 way of as possible, they are usually made of loose fabrics.
"You need to select a really, really tightly woven cloth," Noble says. "We’re talking 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 doubtless too loose, she says, as are most sweaters and other knit yarns. So in case you really can’t sew or put collectively a mask with hair ties as described under, 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 beneficial in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. Should you’re coughing and sneezing, it is best to really be staying inside.
