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

Though cloth masks provide only minimal protection against the spread of COVID-19 and different viruses, the Centers for Illness Control and Prevention (CDC) now advocate that everybody use them when leaving the house. The hope is that this low-risk, comparatively simple intervention could make a dent within the spread of COVID-19 by individuals with no signs or extremely mild ones.

But masks aren’t precisely easy to come by: Medical-grade ones are already briefly provide for healthcare workers who want them, so healthy folks 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 lots of on-line stores. For those who’re trying to figure out if and the way you need to cover your face in your next essential journey out of the house—for a stroll on an uncrowded street or to buy obligatory groceries, for instance—right here’s a guide to all your options.

Things to search for and keep away from when buying a material mask

Lots of crafters and makers, as well as companies that usually sell other material products, at the moment are providing non-medical masks for sale. But not all of those masks are created equal. When you’re ordering protective equipment online, here’s what to look for:

Don’t purchase medical-grade, filtering masks unless you might be immunocompromised or are caring for someone sick with COVID-19. Hospitals are experiencing extreme shortages of these masks, and they don’t seem to be shown to provide significant protection for healthy individuals.

Your masks should cover your nostril and mouth and should have fastenings that keep it firmly in place while you speak, move, and breathe. If you need to contact your face to adjust your masks, you risk exposing your nostril or mouth to germs.

Ideally, the masks should have some sort 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 next finest thing, and your masks ought to have a minimum of layers of it.

Your mask needs to be easy to sanitize by boiling or throwing in the washing machine. Meaning it shouldn’t have material glues, delicate supplies, or funky decorations (other than prints on the material). Gildings 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 cloth covers and chainmail overlays, for instance—keep in mind that this outer layer is being uncovered to viral particles. You need to remove it and sanitize it just like 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-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 easy to breath via as potential, they tend to be made of loose fabrics.

“You want to select a really, really tightly woven fabric,” 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 whenever you pull them are seemingly too loose, she says, as are most sweaters and different knit yarns. So if you really can’t sew or put collectively a masks with hair ties as described under, 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. But all of these workarounds are largely only useful in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. If you happen to’re coughing and sneezing, you need to really be staying inside.
