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

June 6, 2020 00:49

Though fabric masks provide only minimal protection against the spread of COVID-19 and other viruses, the Centers for Disease Management and Prevention (CDC) now suggest that everybody use them when leaving the house. The hope is that this low-risk, comparatively simple intervention could make a dent in the spread of COVID-19 by individuals with no signs or extraordinarily delicate ones.

However masks aren’t exactly easy to come back by: Medical-grade ones are already in short provide for healthcare workers who need them, so healthy folks shouldn’t even attempt to buy them. And within the wake of the CDC’s new suggestions, even non-medical material masks are sold out or backordered in lots of on-line stores. When you’re making an attempt to figure out if and the way it’s best to cover your face on your subsequent essential journey out of the house—for a stroll on an uncrowded avenue or to buy vital groceries, for instance—right here’s a guide to all of your options.

Things to search for and avoid when buying a material mask

A number of crafters and makers, as well as corporations that often sell other material products, at the moment are providing non-medical masks for sale. But not all of those masks are created equal. In case you’re ordering protective equipment online, right here’s what to search for:

Don’t purchase medical-grade, filtering masks unless you’re 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 ought to cover your nostril and mouth and should have fastenings that preserve it firmly in place while you discuss, move, and breathe. If it’s important to contact your face to adjust your masks, you risk exposing your nostril or mouth to germs.

Ideally, the masks ought to have some type of adjustable band to minimize gaps between your nose and your cheeks.

The most effective fabrics are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the subsequent finest thing, and your mask should have at the very least layers of it.

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

If you happen to buy a fashionable cover to go over your mask—some stores are selling glittery fabric covers and chainmail overlays, for example—keep in mind that this outer layer is being exposed to viral particles. You have to remove it and sanitize it just like 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 different 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 easy to breath by way of as attainable, they are typically made of loose fabrics.

“You need 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-high quality bedsheet.”

Jersey materials, towels, and any textiles that stretch whenever you pull them are probably too loose, she says, as are most sweaters and different knit yarns. So in the event 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 efficient and easier to sanitize than a balaclava or wound-up scarf. But all of those 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, it is best to really be staying inside.
