A guide to buying (or making) a face masks 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 advocate 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 people with no symptoms or extremely gentle ones.

However masks aren’t exactly easy to come by: Medical-grade ones are already in short provide for healthcare workers who need them, so healthy individuals shouldn’t even try to purchase them. And within the wake of the CDC’s new recommendations, even non-medical fabric masks are sold out or backordered in many on-line stores. In case you’re making an attempt to figure out if and how you must cover your face in your next essential trip out of the house—for a walk on an uncrowded road or to purchase essential groceries, for example—right here’s a guide to all of your options.

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

Numerous crafters and makers, as well as firms that normally sell other material products, at the moment are providing non-medical masks for sale. But not all of those masks are created equal. In the event you’re ordering protective equipment on-line, right here’s what to search for:

Do not purchase medical-grade, filtering masks unless you are immunocompromised or are caring for someone sick with COVID-19. Hospitals are experiencing excessive shortages of these masks, and they aren't shown to provide significant protection for healthy individuals.

Your masks ought to cover your nostril and mouth and should have fastenings that keep it firmly in place while you talk, 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 should have some sort of adjustable band to attenuate gaps between your nostril and your cheeks.

The most effective fabrics are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following finest thing, and your masks should have not less than layers of it.

Your mask ought to be straightforward to sanitize by boiling or throwing in the washing machine. That means it shouldn’t have fabric glues, delicate supplies, or funky decorations (apart from prints on the material). Embellishments like sequins (sure, there are folks selling sequined masks proper now) provide surfaces that viral particles can linger on for days.

In case you buy a fashionable cover to go over your mask—some stores are selling glittery material covers and chainmail overlays, for example—keep in mind that this outer layer is being exposed to viral particles. You must remove it and sanitize it just like you would with the masks itself.

What a couple of balaclava or scarf?

Rachel Noble, a public health microbiologist at UNC at Chapel Hill, tells PopSci that balaclavas and different 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 straightforward to breath by way of as possible, they are typically made of loose fabrics.

"You need 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-quality bedsheet."

Jersey materials, towels, and any textiles that stretch while you pull them are likely 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 simpler to sanitize than a balaclava or wound-up scarf. However all of those workarounds are mostly only useful in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. In case you’re coughing and sneezing, it's best to really be staying inside.
