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 Illness Management and Prevention (CDC) now recommend that everyone use them when leaving the house. The hope is that this low-risk, comparatively straightforward intervention can make a dent within the spread of COVID-19 by individuals with no symptoms or extraordinarily delicate ones.

But masks aren’t exactly straightforward to return by: Medical-grade ones are already in short supply for healthcare workers who need them, so healthy folks shouldn’t even try to purchase them. And in the wake of the CDC’s new recommendations, even non-medical fabric masks are sold out or backordered in lots of online stores. In the event you’re attempting to determine if and the way you should cover your face in your subsequent essential trip out of the house—for a walk on an uncrowded road or to buy vital groceries, as an illustration—right here’s a guide to all your options.

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

Plenty of crafters and makers, as well as corporations that normally sell other material products, are now providing non-medical masks for sale. However not all of these masks are created equal. For those who’re ordering protective equipment on-line, here’s what to look for:

Do not purchase medical-grade, filtering masks unless you are 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 masks ought to cover your nostril and mouth and will have fastenings that maintain it firmly in place while you talk, move, and breathe. If you have 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 reduce gaps between your nostril and your cheeks.

The simplest materials are waterproof and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following greatest thing, and your mask ought to have no less than two layers of it.

Your mask needs to be straightforward to sanitize by boiling or throwing within the washing machine. That means it shouldn’t have material glues, delicate materials, or funky decorations (aside from prints on the fabric). Gildings like sequins (yes, there are folks selling sequined masks right now) provide surfaces that viral particles can linger on for days.

If you purchase a fashionable cover to go over your mask—some stores are selling glittery material covers and chainmail overlays, for instance—keep in mind that this outer layer is being uncovered to viral particles. You could remove it and sanitize it just such as 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 other warm-weather 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 straightforward to breath through as possible, they are usually 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-quality bedsheet.»

Jersey fabrics, towels, and any textiles that stretch while you pull them are doubtless too loose, she says, as are most sweaters and different knit yarns. So if you happen to really can’t sew or put collectively a masks with hair ties as described beneath, covering your nostril and mouth with a bandana tied round your face is probably slightly more effective and simpler to sanitize than a balaclava or wound-up scarf. However all of these workarounds are principally only beneficial in that they remind you not to touch your face and shield bystanders from the worst of your coughing and sneezing. For those who’re coughing and sneezing, you should really be staying inside.
