A Guide To Buying (or Making) A Face Mask For COVID-19

Though fabric masks provide only minimal protection against the spread of COVID-19 and different viruses, the Centers for Disease Control and Prevention (CDC) now advocate that everybody use them when leaving the house. The hope is that this low-risk, relatively simple intervention can make a dent in the spread of COVID-19 by people with no signs or extremely gentle ones.

But masks aren’t precisely easy to come by: Medical-grade ones are already in brief supply for healthcare workers who want them, so healthy people shouldn’t even try to buy them. And in the wake of the CDC’s new recommendations, even non-medical fabric masks are sold out or backordered in lots of on-line stores. In case you’re trying to figure out if and how you need to cover your face in your next essential journey out of the house—for a stroll on an uncrowded road or to purchase needed groceries, as an example—here’s a guide to all of your options.

Things to look for and avoid when buying a material mask
A lot of crafters and makers, as well as corporations that often sell different material products, are now offering non-medical masks for sale. However not all of these masks are created equal. When you’re ordering protective equipment online, here’s what to search for:

Don't buy 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 aren't shown to provide significant protection for healthy individuals.
Your masks should cover your nose and mouth and should have fastenings that keep it firmly in place while you speak, move, and breathe. If it's a must 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 reduce gaps between your nose and your cheeks.
The simplest fabrics are waterproof and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following finest thing, and your masks should have at the least layers of it.
Your mask needs to be straightforward to sanitize by boiling or throwing in the washing machine. That means it shouldn’t have cloth glues, delicate supplies, or funky decorations (aside from prints on the fabric). Gildings like sequins (sure, there are folks selling sequined masks right now) provide surfaces that viral particles can linger on for days.
When you buy a fashionable cover to go over your mask—some stores are selling glittery material covers and chainmail overlays, for example—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 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 nostril 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 typically made of loose fabrics.

"You want 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-quality bedsheet."

Jersey fabrics, towels, and any textiles that stretch whenever you pull them are possible too loose, she says, as are most sweaters and other knit yarns. So should you really can’t sew or put together a mask with hair ties as described under, 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 those workarounds are principally only beneficial in that they remind you not to contact your face and shield bystanders from the worst of your coughing and sneezing. When you’re coughing and sneezing, it is best to really be staying inside.
