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 different viruses, the Centers for Illness Management and Prevention (CDC) now suggest that everybody use them when leaving the house. The hope is that this low-risk, comparatively straightforward intervention could make a dent within the spread of COVID-19 by people with no symptoms or extraordinarily gentle ones.

But masks aren’t exactly easy to come by: Medical-grade ones are already in brief provide for healthcare workers who want them, so healthy folks shouldn’t even try to purchase them. And in the wake of the CDC’s new recommendations, even non-medical material masks are sold out or backordered in lots of on-line stores. When you’re making an attempt to determine if and how you should cover your face in your subsequent essential journey out of the house—for a walk on an uncrowded road or to purchase essential groceries, for example—here’s a guide to all your options.

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

Plenty of crafters and makers, as well as firms that normally sell different material products, at the moment are offering non-medical masks for sale. But not all of these masks are created equal. In the event you’re ordering protective equipment online, 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 are not shown to provide significant protection for healthy individuals.

Your masks ought to cover your nose and mouth and may have fastenings that keep it firmly in place while you speak, 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 mask should have some kind of adjustable band to reduce gaps between your nostril and your cheeks.

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

Your masks ought to be straightforward to sanitize by boiling or throwing within the washing machine. Which means it shouldn’t have fabric glues, delicate materials, or funky decorations (apart from prints on the fabric). Elaborations like sequins (sure, there are folks 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 cloth covers and chainmail overlays, for example—do not forget that this outer layer is being uncovered 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 other warm-climate 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 possible, they tend to be made of loose fabrics.

“You need to select a really, really tightly woven material,” Noble says. “We’re speaking 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 for those who really can’t sew or put collectively a mask with hair ties as described under, covering your nostril and mouth with a bandana tied round your face is probably slightly more efficient and simpler 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 should really be staying inside.
