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

Although material masks provide only minimal protection against the spread of COVID-19 and different viruses, the Centers for Disease Control and Prevention (CDC) now advocate that everybody use them when leaving the house. The hope is that this low-risk, comparatively easy intervention can make a dent within the spread of COVID-19 by folks with no symptoms or extraordinarily mild ones.

However masks aren’t exactly easy to return by: Medical-grade ones are already in short supply for healthcare workers who need them, so healthy individuals shouldn’t even attempt to purchase them. And in the wake of the CDC’s new suggestions, even non-medical material masks are sold out or backordered in many online stores. For those who’re making an attempt to determine if and how you need to cover your face on your subsequent essential trip out of the house—for a walk on an uncrowded street or to purchase needed groceries, for instance—right here’s a guide to all your options.

Things to look for and avoid when shopping for a cloth masks

A lot of crafters and makers, as well as firms that often sell different material products, are now offering non-medical masks for sale. However not all of those masks are created equal. If you’re ordering protective equipment online, here’s what to search for:

Don’t 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 nostril and mouth and should 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 ought to have some form of adjustable band to attenuate gaps between your nostril and your cheeks.

The best fabrics are water-resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the following finest thing, and your mask ought to have not less than layers of it.

Your masks must be straightforward to sanitize by boiling or throwing in the washing machine. That means it shouldn’t have material glues, delicate supplies, or funky decorations (other than 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 purchase a fashionable cover to go over your masks—some stores are selling glittery cloth covers and chainmail overlays, for instance—keep in mind that this outer layer is being exposed to viral particles. It’s essential to remove it and sanitize it just such as you would with the mask 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 nose and mouth are unlikely to be suitable for stopping the spread of COVID-19. Because they’re designed to be as easy to breath through as doable, they are usually made of loose fabrics.

“You wish to choose 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 while you pull them are possible too loose, she says, as are most sweaters and different knit yarns. So if you happen to really can’t sew or put together a mask with hair ties as described under, covering your nose and mouth with a bandana tied around your face is probably slightly more efficient and simpler to sanitize than a balaclava or wound-up scarf. However all of those workarounds are mostly only helpful in that they remind you to not touch your face and shield bystanders from the worst of your coughing and sneezing. In case you’re coughing and sneezing, you need to really be staying inside.
