Although fabric masks provide only minimal protection towards the spread of COVID-19 and different viruses, the Centers for Illness Control 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 within the spread of COVID-19 by people with no symptoms or extremely mild ones.

However masks aren’t precisely straightforward to come by: Medical-grade ones are already briefly provide for healthcare workers who want them, so healthy folks shouldn’t even try to buy them. And in the wake of the CDC’s new recommendations, even non-medical fabric masks are sold out or backordered in lots of on-line stores. In the event you’re attempting to figure out if and how you must cover your face on your subsequent essential journey out of the house—for a walk on an uncrowded avenue or to buy essential groceries, as an illustration—right here’s a guide to all your options.

Things to look for and keep away from when shopping for a fabric mask
A number of crafters and makers, as well as companies that usually sell different fabric products, are now providing non-medical masks for sale. However not all of these masks are created equal. If you happen to’re ordering protective equipment online, here’s what to search for:

Do not buy medical-grade, filtering masks unless you’re immunocompromised or are caring for someone sick with COVID-19. Hospitals are experiencing excessive shortages of these masks, and they don’t seem to be shown to provide significant protection for healthy individuals.
Your mask ought to cover your nose and mouth and should have fastenings that maintain it firmly in place while you discuss, move, and breathe. If it’s important to touch your face to adjust your masks, you risk exposing your nose or mouth to germs.
Ideally, the mask ought to have some sort of adjustable band to minimize gaps between your nose and your cheeks.
The simplest materials are water resistant and tightly-woven—not stretchy or sheer. A tightly-woven cotton is the subsequent finest thing, and your mask should have a minimum of two layers of it.
Your masks needs to be easy to sanitize by boiling or throwing within the washing machine. Meaning it shouldn’t have fabric glues, delicate materials, or funky decorations (aside from prints on the material). Elaborations like sequins (yes, there are individuals selling sequined masks right now) provide surfaces that viral particles can linger on for days.
In case you purchase 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 uncovered to viral particles. You could remove it and sanitize it just such as you would with the mask 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-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 straightforward to breath by as potential, they tend to be made of loose fabrics.

“You need to select a really, really tightly woven cloth,” 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 possible too loose, she says, as are most sweaters and other knit yarns. So if you happen to really can’t sew or put collectively a mask with hair ties as described below, covering your nose and mouth with a bandana tied around your face is probably slightly more effective and easier to sanitize than a balaclava or wound-up scarf. However all of those workarounds are largely only useful in that they remind you to not contact your face and shield bystanders from the worst of your coughing and sneezing. Should you’re coughing and sneezing, you need to really be staying inside.
