A guide to purchasing (or making) a face masks for COVID-19
Though cloth masks provide only minimal protection towards the spread of COVID-19 and different 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 can make a dent within the spread of COVID-19 by folks with no signs or extraordinarily gentle ones.
But masks aren’t precisely easy to come by: Medical-grade ones are already in short supply for healthcare workers who need them, so healthy individuals shouldn’t even attempt to buy them. And within the wake of the CDC’s new suggestions, even non-medical material masks are sold out or backordered in lots of online stores. If you happen to’re making an attempt to determine if and how you must cover your face on your next essential journey out of the house—for a stroll on an uncrowded road or to buy vital groceries, as an illustration—right here’s a guide to all your options.
Things to search for and keep away from when buying a cloth mask
Lots of crafters and makers, as well as corporations that often sell other cloth products, at the moment are providing non-medical masks for sale. But not all of those masks are created equal. In case you’re ordering protective equipment on-line, here’s what to look for:
Do not purchase medical-grade, filtering masks unless you might be immunocompromised or are caring for someone 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 masks should cover your nostril and mouth and will have fastenings that hold it firmly in place while you talk, move, and breathe. If it’s a must to contact your face to adjust your masks, you risk exposing your nose or mouth to germs.
Ideally, the mask ought to have some kind of adjustable band to attenuate gaps between your nose and your cheeks.
The simplest materials are waterproof and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the next greatest thing, and your mask should have at the least layers of it.
Your mask needs to be simple to sanitize by boiling or throwing within the washing machine. That means it shouldn’t have material glues, delicate supplies, or funky decorations (apart from prints on the material). Elaborations like sequins (yes, there are people 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 material 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 such as 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 other 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 attainable, they tend to be made of loose fabrics.
“You need to select 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 materials, towels, and any textiles that stretch whenever you pull them are likely too loose, she says, as are most sweaters and different knit yarns. So in case you really can’t sew or put together a masks with hair ties as described beneath, covering your nose and mouth with a bandana tied around your face is probably slightly more effective and simpler to sanitize than a balaclava or wound-up scarf. But all of those workarounds are mostly only beneficial in that they remind you not to 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.
