Though cloth masks provide only minimal protection in opposition to the spread of COVID-19 and different viruses, the Centers for Disease Management and Prevention (CDC) now recommend that everybody use them when leaving the house. The hope is that this low-risk, comparatively simple intervention can make a dent within the spread of COVID-19 by individuals with no signs or extraordinarily gentle ones.
However masks aren’t precisely easy to come by: Medical-grade ones are already in short provide for healthcare workers who want them, so healthy people 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. If you’re attempting to determine if and how you must cover your face on your subsequent essential journey out of the house—for a walk on an uncrowded road or to purchase obligatory groceries, as an example—right here’s a guide to all of your options.
Things to search for and avoid when buying a cloth masks
A number of crafters and makers, as well as corporations that often sell other cloth products, at the moment are offering non-medical masks for sale. But not all of these masks are created equal. When you’re ordering protective equipment on-line, right here’s what to search for:
Do not purchase medical-grade, filtering masks unless you are immunocompromised or are caring for somebody sick with COVID-19. Hospitals are experiencing extreme shortages of those masks, and they don’t seem to be shown to provide significant protection for healthy individuals.
Your mask ought to cover your nose and mouth and may have fastenings that maintain it firmly in place while you speak, move, and breathe. If you have to contact your face to adjust your mask, you risk exposing your nose or mouth to germs.
Ideally, the mask should have some form of adjustable band to attenuate gaps between your nostril and your cheeks.
The best fabrics are waterproof and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the next best thing, and your mask ought to have no less than two 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 supplies, or funky decorations (other than prints on the fabric). Embellishments like sequins (sure, there are folks selling sequined masks right now) provide surfaces that viral particles can linger on for days.
If you happen to 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. It’s essential to remove it and sanitize it just such as 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 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 as doable, they are usually made of loose fabrics.
“You wish to select 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-high quality bedsheet.”
Jersey materials, towels, and any textiles that stretch when you pull them are seemingly too loose, she says, as are most sweaters and different knit yarns. So in the event 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 principally only helpful in that they remind you not to touch your face and shield bystanders from the worst of your coughing and sneezing. In case you’re coughing and sneezing, it is best to really be staying inside.
