Though cloth masks provide only minimal protection against the spread of COVID-19 and other viruses, the Centers for Disease Management and Prevention (CDC) now advocate that everyone use them when leaving the house. The hope is that this low-risk, comparatively straightforward intervention can make a dent in the spread of COVID-19 by individuals with no signs or extremely gentle ones.
However masks aren’t precisely simple to return by: Medical-grade ones are already in short supply for healthcare workers who want them, so healthy individuals shouldn’t even attempt to buy them. And in the wake of the CDC’s new suggestions, even non-medical cloth masks are sold out or backordered in lots of on-line stores. Should you’re trying to figure out if and how it is best to cover your face in your next essential trip out of the house—for a stroll on an uncrowded avenue or to purchase necessary groceries, as an example—right here’s a guide to all your options.
Things to look for and avoid when buying a fabric masks
Lots of crafters and makers, as well as companies that normally sell different cloth products, are actually providing non-medical masks for sale. But not all of these masks are created equal. If you happen to’re ordering protective equipment on-line, here’s what to search for:
Don’t purchase medical-grade, filtering masks unless you might be immunocompromised or are caring for someone sick with COVID-19. Hospitals are experiencing excessive shortages of these masks, and they don’t seem to be shown to provide significant protection for healthy individuals.
Your mask should cover your nostril and mouth and should have fastenings that hold it firmly in place while you discuss, move, and breathe. If it’s important to contact your face to adjust your masks, you risk exposing your nostril or mouth to germs.
Ideally, the mask should have some form of adjustable band to minimize gaps between your nose and your cheeks.
The best fabrics are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following greatest thing, and your mask should have at the least layers of it.
Your masks must be straightforward to sanitize by boiling or throwing in the washing machine. Which means it shouldn’t have fabric glues, delicate materials, or funky decorations (apart from prints on the fabric). Gildings like sequins (sure, 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 masks—some stores are selling glittery material covers and chainmail overlays, for instance—remember that this outer layer is being exposed to viral particles. You should remove it and sanitize it just like you would with the mask 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-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 through as attainable, 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-quality bedsheet.”
Jersey fabrics, towels, and any textiles that stretch while you pull them are seemingly too loose, she says, as are most sweaters and different knit yarns. So when 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 efficient and simpler to sanitize than a balaclava or wound-up scarf. However all of these workarounds are largely only beneficial in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. When you’re coughing and sneezing, it’s best to really be staying inside.
