A guide to purchasing (or making) a face mask for COVID-19
Though cloth masks provide only minimal protection towards the spread of COVID-19 and other viruses, the Centers for Illness Management and Prevention (CDC) now advocate that everyone use them when leaving the house. The hope is that this low-risk, relatively straightforward intervention could make a dent within the spread of COVID-19 by individuals with no symptoms or extremely gentle ones.
However masks aren’t precisely straightforward to come by: Medical-grade ones are already in brief supply for healthcare workers who need them, so healthy folks shouldn’t even attempt to buy them. And in the wake of the CDC’s new recommendations, even non-medical cloth masks are sold out or backordered in many online stores. In case you’re trying to determine if and the way it’s best to cover your face on your next essential journey out of the house—for a walk on an uncrowded street or to purchase needed groceries, for example—here’s a guide to all your options.
Things to search for and keep away from when shopping for a fabric mask
A lot of crafters and makers, as well as corporations that usually sell different fabric products, at the moment are offering non-medical masks for sale. However not all of those masks are created equal. If you’re ordering protective equipment on-line, here’s what to look 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 masks should cover your nose and mouth and should have fastenings that preserve it firmly in place while you discuss, move, and breathe. If you need to contact your face to adjust your masks, you risk exposing your nose or mouth to germs.
Ideally, the masks ought to have some kind of adjustable band to attenuate gaps between your nose and your cheeks.
The most effective materials are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the subsequent best thing, and your masks ought to have a minimum of layers of it.
Your masks must 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 (other than prints on the fabric). Embellishments like sequins (sure, there are people selling sequined masks proper now) provide surfaces that viral particles can linger on for days.
In case you buy a fashionable cover to go over your mask—some stores are selling glittery cloth covers and chainmail overlays, for instance—do not forget 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 a few balaclava or scarf?
Rachel Noble, a public health microbiologist at UNC at Chapel Hill, tells PopSci that balaclavas and other warm-climate gear designed to cover your nose and mouth are unlikely to be suitable for stopping the spread of COVID-19. Because they’re designed to be as simple to breath through as attainable, they are typically made of loose fabrics.
“You need to choose a really, really tightly woven cloth,” 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 fabrics, towels, and any textiles that stretch when you pull them are probably too loose, she says, as are most sweaters and different knit yarns. So in case you really can’t sew or put together a mask with hair ties as described beneath, covering your nose and mouth with a bandana tied round your face is probably slightly more effective 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 to not touch your face and shield bystanders from the worst of your coughing and sneezing. Should you’re coughing and sneezing, it’s best to really be staying inside.
