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

Though fabric masks provide only minimal protection in opposition to the spread of COVID-19 and other viruses, the Centers for Disease Management and Prevention (CDC) now recommend that everyone use them when leaving the house. The hope is that this low-risk, relatively simple intervention can make a dent within the spread of COVID-19 by individuals with no symptoms or extraordinarily gentle ones.

However masks aren’t precisely easy to come back by: Medical-grade ones are already briefly provide for healthcare workers who need them, so healthy individuals shouldn’t even attempt to buy them. And in the wake of the CDC’s new suggestions, even non-medical fabric masks are sold out or backordered in many online stores. If you happen to’re trying to figure out if and the way it is best to cover your face on your next essential journey out of the house—for a walk on an uncrowded street or to purchase essential groceries, for example—right here’s a guide to all your options.

Things to search for and keep away from when shopping for a cloth masks

A number of crafters and makers, as well as companies that usually sell different cloth products, at the moment are offering non-medical masks for sale. However not all of those masks are created equal. In the event you’re ordering protective equipment on-line, right here’s what to look for:

Don’t buy medical-grade, filtering masks unless you’re immunocompromised or are caring for somebody sick with COVID-19. Hospitals are experiencing excessive 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 may have fastenings that preserve it firmly in place while you speak, move, and breathe. If it’s important to contact your face to adjust your masks, you risk exposing your nostril or mouth to germs.

Ideally, the mask should have some sort of adjustable band to attenuate gaps between your nose and your cheeks.

The best fabrics are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the subsequent best thing, and your mask ought to have a minimum of two layers of it.

Your masks should be straightforward to sanitize by boiling or throwing within 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 (sure, there are folks selling sequined masks proper now) provide surfaces that viral particles can linger on for days.

If 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. You will need to remove it and sanitize it just such as you would with the masks 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-weather gear designed to cover your nostril and mouth are unlikely to be suitable for stopping the spread of COVID-19. Because they’re designed to be as simple to breath by as doable, they are typically made of loose fabrics.

“You need to choose a really, really tightly woven material,” 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 once you pull them are possible too loose, she says, as are most sweaters and other knit yarns. So when you really can’t sew or put collectively a masks with hair ties as described beneath, covering your nostril and mouth with a bandana tied around your face is probably slightly more efficient and easier to sanitize than a balaclava or wound-up scarf. But all of those workarounds are principally only helpful 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.
