A guide to purchasing (or making) a face mask for COVID-19

Though material masks provide only minimal protection against the spread of COVID-19 and other viruses, the Centers for Illness Control and Prevention (CDC) now recommend that everybody use them when leaving the house. The hope is that this low-risk, relatively simple intervention could make a dent in the spread of COVID-19 by folks with no symptoms or extremely mild ones.

However masks aren’t precisely simple to return by: Medical-grade ones are already in short supply for healthcare workers who want them, so healthy people shouldn’t even attempt to purchase them. And within the wake of the CDC’s new suggestions, even non-medical material masks are sold out or backordered in many on-line stores. If you happen to’re making an attempt to figure out if and the way it is best to cover your face in your subsequent essential trip out of the house—for a stroll on an uncrowded road or to buy essential groceries, for instance—right here’s a guide to all your options.

Things to search for and keep away from when buying a cloth masks
Numerous crafters and makers, as well as companies that usually sell different fabric products, at the moment are providing non-medical masks for sale. However not all of those masks are created equal. In case you’re ordering protective equipment on-line, right here’s what to look for:

Do not buy medical-grade, filtering masks unless you might be immunocompromised or are caring for somebody sick with COVID-19. Hospitals are experiencing extreme shortages of these masks, and they are not shown to provide significant protection for healthy individuals.
Your mask should cover your nose and mouth and will have fastenings that keep it firmly in place while you discuss, move, and breathe. If it’s a must to touch your face to adjust your mask, 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 best materials are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the next finest thing, and your mask should have no less than two layers of it.
Your mask should be straightforward to sanitize by boiling or throwing in the washing machine. That means it shouldn’t have fabric glues, delicate materials, or funky decorations (aside from prints on the fabric). Embellishments like sequins (yes, there are folks selling sequined masks proper now) provide surfaces that viral particles can linger on for days.
In the event you buy a fashionable cover to go over your masks—some stores are selling glittery material covers and chainmail overlays, for instance—do not forget that this outer layer is being exposed to viral particles. You will need 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 preventing the spread of COVID-19. Because they’re designed to be as simple to breath by way of as attainable, they are usually made of loose fabrics.

“You wish to select a really, really tightly woven material,” Noble says. “We’re talking 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 other knit yarns. So in case you really can’t sew or put together a masks with hair ties as described below, covering your nose and mouth with a bandana tied round your face is probably slightly more efficient and simpler to sanitize than a balaclava or wound-up scarf. However all of those 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. In the event you’re coughing and sneezing, it is best to really be staying inside.
