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

Although 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 everybody use them when leaving the house. The hope is that this low-risk, relatively easy intervention could make a dent in the spread of COVID-19 by individuals with no signs or extremely gentle ones.

But masks aren’t exactly straightforward to come by: Medical-grade ones are already in short supply for healthcare workers who want them, so healthy people shouldn’t even try to buy them. And in the wake of the CDC’s new recommendations, even non-medical cloth masks are sold out or backordered in lots of on-line stores. In case you’re making an attempt to determine if and the way it’s best to cover your face in your subsequent essential trip out of the house—for a stroll on an uncrowded road or to buy obligatory groceries, as an illustration—right here’s a guide to all your options.

Things to search for and avoid when shopping for a material mask

Lots of crafters and makers, as well as corporations that usually sell different fabric products, are actually providing non-medical masks for sale. But not all of these masks are created equal. If you’re ordering protective equipment online, right 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 aren’t shown to provide significant protection for healthy individuals.

Your mask should cover your nose and mouth and will have fastenings that maintain it firmly in place while you discuss, 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 masks ought to have some kind of adjustable band to minimize 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 best thing, and your mask should have no less than layers of it.

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

If you buy a fashionable cover to go over your mask—some stores are selling glittery material covers and chainmail overlays, for example—remember that this outer layer is being exposed to viral particles. You could 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 other warm-climate 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 simple to breath by way of as attainable, they are usually 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 if you pull them are possible too loose, she says, as are most sweaters and other knit yarns. So in the event you really can’t sew or put collectively a mask with hair ties as described below, covering your nose 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. However all of those workarounds are mostly only beneficial in that they remind you not to contact your face and shield bystanders from the worst of your coughing and sneezing. In the event you’re coughing and sneezing, it is best to really be staying inside.
