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

Though cloth masks provide only minimal protection in opposition to 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, relatively straightforward intervention could make a dent within the spread of COVID-19 by people with no symptoms or extraordinarily gentle ones.

However masks aren’t exactly simple to return by: Medical-grade ones are already in brief supply for healthcare workers who want them, so healthy individuals shouldn’t even try to purchase them. And within the wake of the CDC’s new recommendations, even non-medical material masks are sold out or backordered in lots of on-line stores. If you’re attempting to determine 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 avenue or to purchase obligatory groceries, for example—right here’s a guide to all of your options.

Things to look for and keep away from when shopping for a cloth mask
A lot of crafters and makers, as well as companies that normally sell different material products, at the moment are offering non-medical masks for sale. But not all of these masks are created equal. For those who’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 extreme shortages of these masks, and they are not shown to provide significant protection for healthy individuals.
Your mask ought to cover your nose and mouth and may have fastenings that keep it firmly in place while you speak, move, and breathe. If it’s important to contact your face to adjust your mask, you risk exposing your nostril or mouth to germs.
Ideally, the mask should have some type of adjustable band to attenuate gaps between your nose and your cheeks.
The simplest materials are waterproof and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the subsequent best thing, and your mask ought to have at the very least two layers of it.
Your mask needs to be easy to sanitize by boiling or throwing in the washing machine. Meaning it shouldn’t have cloth glues, delicate supplies, or funky decorations (other than prints on the fabric). Elaborations like sequins (sure, there are folks selling sequined masks right now) provide surfaces that viral particles can linger on for days.
Should you purchase a fashionable cover to go over your mask—some stores are selling glittery fabric covers and chainmail overlays, for instance—do not forget that this outer layer is being uncovered to viral particles. You will need to remove it and sanitize it just such as 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-climate 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 via as doable, they are typically 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-quality bedsheet.”

Jersey fabrics, towels, and any textiles that stretch whenever you pull them are doubtless too loose, she says, as are most sweaters and other knit yarns. So for those who 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 effective and simpler to sanitize than a balaclava or wound-up scarf. But all of these workarounds are largely only beneficial 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 must really be staying inside.
