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

Although fabric masks provide only minimal protection against the spread of COVID-19 and other viruses, the Centers for Disease Management and Prevention (CDC) now suggest that everyone use them when leaving the house. The hope is that this low-risk, comparatively easy intervention can make a dent in the spread of COVID-19 by people with no symptoms or extraordinarily gentle ones.

However masks aren’t exactly easy to come by: Medical-grade ones are already in short 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 suggestions, even non-medical fabric masks are sold out or backordered in lots of on-line stores. Should you’re attempting to determine if and how you need to cover your face in your next essential journey out of the house—for a walk on an uncrowded avenue or to buy mandatory groceries, for instance—right here’s a guide to all your options.

Things to search for and avoid when shopping for a fabric masks
Plenty of crafters and makers, as well as firms that usually sell other fabric products, are actually providing non-medical masks for sale. But not all of these masks are created equal. In the event you’re ordering protective equipment on-line, 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 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 will have fastenings that keep it firmly in place while you talk, 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 kind of adjustable band to minimize gaps between your nose and your cheeks.
The simplest materials are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following greatest thing, and your masks should have a minimum of two layers of it.
Your masks must be straightforward to sanitize by boiling or throwing within the washing machine. Which means it shouldn’t have material glues, delicate supplies, or funky decorations (other than prints on the material). Elaborations like sequins (sure, there are individuals selling sequined masks right now) provide surfaces that viral particles can linger on for days.
Should you buy a fashionable cover to go over your masks—some stores are selling glittery cloth covers and chainmail overlays, for example—remember that this outer layer is being exposed to viral particles. You need to remove it and sanitize it just like 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 different warm-climate 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 way of as attainable, they tend to be made of loose fabrics.

"You want to select a really, really tightly woven fabric," 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 possible too loose, she says, as are most sweaters and other knit yarns. So if you really can’t sew or put together a masks with hair ties as described below, covering your nostril and mouth with a bandana tied around your face is probably slightly more effective and easier to sanitize than a balaclava or wound-up scarf. But all of those workarounds are largely only useful in that they remind you not to contact your face and shield bystanders from the worst of your coughing and sneezing. If you’re coughing and sneezing, it's best to really be staying inside.
