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

Though cloth masks provide only minimal protection towards the spread of COVID-19 and different 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 can make a dent in the spread of COVID-19 by individuals with no signs or extremely mild ones.

However masks aren’t exactly easy to come back by: Medical-grade ones are already in brief provide for healthcare workers who want them, so healthy people shouldn’t even attempt 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. Should you’re making an attempt to figure out if and how it’s best to cover your face on your subsequent essential trip out of the house—for a stroll on an uncrowded street or to purchase needed groceries, for instance—here’s a guide to all of your options.

Things to search for and avoid when buying a fabric masks

Lots of crafters and makers, as well as firms that usually sell different cloth products, are actually offering non-medical masks for sale. However not all of these masks are created equal. If you happen to’re ordering protective equipment on-line, right here’s what to look for:

Do not 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 aren’t shown to provide significant protection for healthy individuals.

Your mask should cover your nose and mouth and will have fastenings that keep it firmly in place while you speak, move, and breathe. If it’s important to touch your face to adjust your masks, you risk exposing your nostril or mouth to germs.

Ideally, the mask ought to have some type of adjustable band to minimize 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 best thing, and your masks should have a minimum of layers of it.

Your masks must be simple to sanitize by boiling or throwing in the washing machine. Meaning it shouldn’t have material glues, delicate materials, or funky decorations (apart from prints on the material). Embellishments like sequins (sure, there are individuals selling sequined masks proper now) provide surfaces that viral particles can linger on for days.

When you purchase a fashionable cover to go over your masks—some stores are selling glittery fabric covers and chainmail overlays, for instance—remember that this outer layer is being uncovered to viral particles. It’s essential 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 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 wish 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 materials, towels, and any textiles that stretch when 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 together a masks with hair ties as described below, covering your nostril and mouth with a bandana tied round your face is probably slightly more effective and easier to sanitize than a balaclava or wound-up scarf. But all of those workarounds are largely only useful in that they remind you not to touch your face and shield bystanders from the worst of your coughing and sneezing. Should you’re coughing and sneezing, it’s best to really be staying inside.
