If You Can't Find an N95, This Could Be the Next Best Thing, Study Shows
This common household item could be the key to better protecting yourself against COVID, a new study shows.
While N95 masks may still be in short supply as the COVID pandemic rages on, there may be a clever solution that keeps you nearly as protected as medical-grade PPE. According to a new study, a dry baby wipe could be the key to making your mask nearly as protective as an N95. Read on to learn more about this science-backed hack, and for more mask tips you need to know, find out why If Your Mask Doesn't Have These 4 Things, Get a New One, Doctor Says.
For their study, researchers out of the University of British Columbia tested multiple mask styles and 41 different fabrics to see how they blocked droplets. After comparing the results, they concluded that masks that consist of two layers of low-thread-count quilting cotton plus a three-ply dried baby wipe as a filter were very effective at stopping droplets from spreading.
"Baby wipes are typically made of spunlace and spunbond polypropylene—similar to the types of polypropylene found in medical masks and N95 respirators," Jane Wang, PhD, a clinical professor in the faculty of medicine at the University of British Columbia School of Biomedical Engineering, explained in a statement.
In fact, according to Steven N. Rogak, PhD, a University of British Columbia professor of mechanical engineering who specializes in aerosols, “A well-fitted, well-designed cloth mask with a baby-wipe filter will be more effective at filtering 5- or 10-micron particles than a poorly fitted N95 mask.”
According to a 2012 research article published in BMC Pulmonary Medicine, the average human cough aerosol ranges from .01 to 900 microns in size, suggesting that the addition of a dry baby wipe filter to an average cloth mask could be enough to keep COVID-contaminated respiratory droplets from spreading.
However, that’s not the only way experts say you can make your mask safer. Read on to discover what to do to ensure you’ve got the best protection against COVID. And for the latest mask news, Dr. Fauci Says the CDC May Make This Major Mask Change Soon.

Make sure that your mask is made of material that’s comfortable and protective.
While cloth masks may be the standard for everyday wear for many people, the type of material your mask is made of may significantly factor into its efficacy.
According to the University of British Columbia researchers, the outer layer of a mask should ideally be made of knit nylon, polyester satin, double-knit cotton, or quilting cotton; simple-weave silk, double-knit cotton, or quilting cotton for the inner layer; and a filter in between. The researchers noted that, in addition to the protection conferred by the aforementioned mask components, their comfort and breathability makes them easy to wear over a prolonged period of time.

Ensure that your mask doesn’t gap.
N95s may be the gold standard when it comes to protection against COVID, but any mask you wear is only as good as its fit. “Even an N95 mask is going to take in large, massive droplets with lots of viruses if it does not seal against the face,” says Rogak, who explains that pleated masks are the most prone to gapping and leaking. “You need to create a bit of an air pocket, with a bigger curvature in front, so that the whole mask is engaged in air exchange.” And for more on the masks to steer clear of, check out The CDC Warns Against Using These 6 Face Masks.
Wash your mask if it’s reusable (and don't reuse one that's not).
If you’re wearing a reusable mask, the CDC recommends washing it at least once a day, and preferably every time it gets dirty. In fact, according to a study published in the Sept. 2020 volume of BMJ Open, “a well-washed cloth mask can be as protective as a medical mask.”
However, attempting to reuse an N95 by washing it may be a fatal error. The University of British Columbia researchers found that washing N95 masks with soap and water can “significantly reduce their filtration properties.” And for more COVID safety news delivered to your inbox, sign up for our daily newsletter.
Don’t wear vented masks.
Though they may seem as though they’d make it easier to breathe, if your masks has vents, it’s not stopping the spread of COVID. According to the Centers for Disease Control and Prevention (CDC), vented masks “may not prevent you from spreading COVID-19 to others. The hole in the material may allow your respiratory droplets to escape."
