Simply Wearing a Mask Isn’t Enough
By now, you know face masks can help prevent the transmission of the novel coronavirus. As of late April 2020, at least seven states require people to wear them when visiting essential businesses or taking public transportation. The Centers for Disease Control and Prevention (CDC) recommends it for most people, especially when it’s difficult to maintain the recommended six feet of social distance. “The grocery store is a perfect example [of when to wear one],” says Ann Marie Pettis, RN, the president-elect of the Association for Professionals in Infection Control and Epidemiology (APIC). Since there’s a shortage of medical-grade masks, people are crafting DIY options from cloth to comply and stay safe. But masks only work when worn and cared for correctly. Don’t make these mistakes.
Using the Wrong Materials
Ideally, a mask that effectively filters out coronavirus particles should be made of breathable fabric. After all, if it’s not comfortable, you’re less likely to wear it correctly.
A recent study gives certain fabrics the edge in both categories. When researchers studied 30 materials ranging from bra pads to coffee filters, those faring best were lightweight denim, paper towels, and 100 percent cotton bedsheets with an 80 to 120 thread count. Fabrics made with natural fibers and a tighter weave also filtered out virus particles better.
Here’s a good rule of thumb: If you hold your fabric up to the light and can see through it, the weave is too loose. Additionally, whatever material you use, it should be machine washable and dryable so you can clean it regularly.
Putting it On and Taking it Off Incorrectly
If you remember nothing else, remember to wash your hands first so you’re not inadvertently transferring virus particles to your mask and face. National Jewish Health recommends scrubbing your hands with soap and water for 20 seconds immediately before and after putting on a mask, and again immediately before and after removing it. “The main message is hand hygiene,” Pettis says. “You can’t overdo it.” Just be sure to moisturize frequently, she adds, so your skin doesn’t develop small abrasions that could invite infection.
After you’ve washed, handle the mask only by the ear loops or ties. Secure one end first, and then stretch it over your mouth and nose. If you wear glasses, put those on last. To prevent your lenses from fogging, wash them first with soapy water. You could also try FogTech DX wipes.
When taking off the mask, remove it from behind, taking care again to grab the ear loops instead of touching the fabric. If your mask has ties, undo the bottom one first, then the top one, according to recommendations from the University of Utah Health. Finally, pull the mask away from your face and then down.
Wearing it the Wrong Way
If your mask has pleats, they go on the outside, and the folded edge should be on the bottom. The mask should fit snugly, covering your nose and mouth completely without gaps but still allowing you to breathe naturally, according to the CDC. The sides of the mask should extend at least an inch past each corner of your mouth, and the bottom should wrap under your chin, which serves as an anchor, notes Consumer Reports. Men may need to trim their beards to ensure a good fit.
Putting it On Too Late
Many people put on their masks as they enter a grocery store or other essential business, but that may be too late because unforeseen interactions can occur earlier, Baylor College of Medicine’s Dr. Allison Haddock told a Houston news channel. Ideally, you should put on your mask before you step out of your front door. If you live in an apartment, that’s especially important, says the New York Times, noting that elevators and stairwells can be especially germy.
Taking it Off Too Early
Likewise, removing your mask when you get in your car might be too soon. Dr. Haddock recommends waiting until you’re home where you can remove it properly and wash your hands right away. If you must remove it sooner, don’t just toss it on the passenger seat; place it in a bag and use hand sanitizer before you touch anything else.
You can probably wear the same mask the whole time you’re out, for up to 12 hours, Pettis says, as long as it isn’t moist from your breath. “As soon as any mask becomes moist, it’s no longer effective and needs to be changed.”
Stop touching your face. Really. “The thing I’ve noticed primarily is people not realizing they’re touching the mask,” Pettis says. “They’re adjusting it, fiddling with it, potentially contaminating their hands,” or pulling it down to take a quick bite or drink. Any of these actions could introduce the coronavirus or other germs into your nose, mouth or eyes. If you absolutely must adjust it, clean your hands before and afterward.
“The other thing I’ve noticed is people pulling the mask down and wearing it around their neck. It’s hanging there and collecting germs,” Pettis says. “A mask is either on or it’s off.”
If you wear a mask frequently or always feel like scratching your nose when it’s on, consider using an anti-chafing balm like Body Glide. Or try the same company’s newest product, Face Glide, which the manufacturer says “forms a dry, invisible barrier to protect your skin against the effects of friction and rubbing.”
Putting Masks on the Wrong People
The CDC warns that infants and children under two should never wear masks. For one thing, their airways are smaller, making breathing through a mask more difficult, reports Nationwide Children’s Hospital in Columbus, Ohio. If babies do struggle to breathe, they’re unable to remove masks themselves, which could lead to suffocation. They also can’t follow instructions not to touch their masks. For similar reasons, people with dementia or other cognitive disabilities should not wear masks, though their caregivers should.
Finally, people with underlying respiratory conditions should forgo masks, as they may not be able to breathe adequately while wearing one. These four household products that kill coronavirus, according to Consumer Reports.
Not Washing Your Mask
If you wear a cloth mask frequently, it’s best to wash it every time you wear it. Use detergent in the hottest water the fabric can withstand. This is not the time to think about brightening the colors. “Heat will definitely kill this germ,” Pettis says. For that reason, experts also advise tumbling the masks in the dryer on the hottest setting the material will tolerate.
If you’re wearing a mask only occasionally, you can let it dry out in a paper bag between uses. “If you wore it once and it’s been a week since then, it’s probably fine to put it back on,” Pettis says, because the virus most likely doesn’t survive more than a day or two on soft surfaces.
The Internet is rife with other ideas to clean your mask faster, like spraying it with disinfectant or bleach, or sanitizing it in the microwave. Experts don’t recommend either method. Even if the chemicals from a disinfectant spray dissipate before you wear the mask again, it could still cause a respiratory or skin reaction. Besides, Pettis says, such products probably don’t do as good a job of removing virus particles from soft surfaces as it does from hard ones. Speaking of which, these are the 14 ways you’re probably using disinfectants wrong.
Meanwhile, New Hampshire firefighters report they’ve been responding to house fires caused by masks overheating in the microwave. It’s not worth the risk just to avoid another load of laundry.
Storing it Wrong
Even if you’re letting your mask dry between infrequent wearings, don’t just hang it on a hook next to your jacket and grab it the next time you head out. Between washings, it’s best to store it in a clean, dry paper bag so its surface remains free from any germs that might be present in your home. And avoid using plastic bags as they can encourage germ growth. “Put it in a paper bag and let it sit for a few days before you wear it again, or launder it,” Pettis says.
Wearing it for the Wrong Reason
“Wearing a mask in public is not so much protecting you as it’s protecting others around you in that six feet of space,” Pettis says. A growing body of research suggests the novel coronavirus is likely spread by people who don’t show symptoms. That could even be you. And that’s the most important reason to wear a mask.
