Properly wearing surgical masks is effective in preventing diseases transmitted through respiratory droplets. After our last test in 2017, the Council again collected 30 face mask models for testing, examining the quality of disposable masks in the market.

Many people are currently restocking their face masks supply due to concerns about spiking COVID cases. And there are many options to choose from, like reusable cloth masks, disposable masks, respirators and even gaiters.
In its guide to masks and respirators, the Centers for Disease Control and Prevention says respirators — among them N95 and KN95 face masks — offer more protection than cloth masks. (Most people use “mask” and “respirator” interchangeably, but when the CDC and medical professionals say “respirator,” they specifically mean specialized, fitted face coverings like N95s, KN95s and KF94s.)
Highest level of protection: Well-fitting respirators approved by the National Institute for Occupational Safety & Health (NIOSH), including N95s
Less protection than NIOSH-approved respirators: Well-fitting disposable surgical masks and KN95s
Less protection than non-NIOSH respirators and surgical masks: Layered, finely woven products
Least protection (but still better than not wearing a mask at all): Loosely woven cloth products

When it comes to shopping for disposable face masks, experts suggest considering the following factors:
Medical-grade versus nonmedical-grade: Medical-grade face masks are regulated by the Food and Drug Administration and must meet strict criteria in order to be considered medical devices. Nonmedical-grade face masks, on the other hand, are not regulated by the FDA, as they are not intended for use in medical settings, says Dr. Jeannie Kenkare, chief medical officer and co-founder of Northeast-based PhysicianOne Urgent Care. Experts tell us that nonmedical-grade disposable masks are a fine option for the general public. But if you're in a high-risk group, you may want to consider opting for medical-grade disposable masks since they offer a guaranteed level of protection.
Fit: Disposable masks should fit tightly around your nose, mouth and chin so they create a seal against your face to prevent leaks.
Features: The CDC recommends buying disposable face masks that are made from multiple layers of material — experts tell us your mask should be at least two-ply, but three-ply is ideal. Masks should also have a nose wire, and experts say you can look for options that have an inner lining with moisture-wicking and antibacterial properties. Be sure you do not buy masks with exhalation valves.
The FDA does not maintain a list of surgical mask suppliers. However, Linsey Marr, a professor of civil and environmental engineering at Virginia Tech, suggests looking for products that say they're ASTM Level 1, 2 or 3 on the package. “This means the mask can filter out at least 95% of particles of all sizes, and at least 98% for Levels 2 and 3,” she says.
If you’re looking to purchase a medical-grade disposable mask, Marr says the difference among ASTM Levels 1, 2 and 3 “is probably not significant for everyday use, where fit is more important.” In other words, a leaky surgical mask — one that fits your face poorly and has gaps along the sides and top — is not effective.

There are two types of disposable face masks: Medical-grade (also referred to as surgical masks or medical procedure masks) and nonmedical-grade. And “while all surgical masks are considered face masks, not all face masks are considered surgical face masks,” says Dr. Jay Woody, chief medical officer of Intuitive Health and a co-founder of Legacy ER...
Disposable face masks protect those around the wearer by blocking virus particles from entering the air, thus decreasing the chance that someone infected with Covid will spread the virus, says Dr. Carl Fichtenbaum, a professor of clinical medicine at the University of Cincinnati College of Medicine. To some extent, they also help shield what the wearer breathes in. And the masks can prevent wearers from touching a contaminated surface and then touching their eyes, mouth or nose, Woody says.
Because nonmedical-grade disposable masks are not regulated by the FDA, there is no uniform design standard they follow, but most have at least two layers. Medical-grade masks, however, are regulated by the FDA and adhere to specific standards. The outer layer is typically water-repellent to protect against large droplets, the middle layer usually has an antibacterial filter and the inner layer is designed to absorb moisture from the breath and minimize skin irritation, says Dr. Manisha Singal, a board-certified internal medicine physician and chief medical officer of Bridgepoint Hospital in Washington, D.C, where she is a critical care physician.
A face mask will not protect you or the people around you unless you wear it correctly. The CDC recommends making sure it completely covers your mouth and nose and fits tightly against your face to prevent gaps around the sides of the mask, nose and chin. You also should not wear any mask with exhalation valves or vents, according to the CDC.
All masks fit differently, and features like adjustable ear loops and an adjustable nose bridge help you improve the fit of your mask, as do mask fitters or braces, according to the CDC. Using a fitter or brace is especially a good idea for people with facial hair, which can make it difficult to achieve a tight fit.
What medical-grade face masks, nonmedical-grade face masks and respirators all have in common is that they’re designed to be single-use face coverings. That doesn’t actually mean you have to toss your mask after a single use, however. Depending on the mask and how long you wear it for, it can be worn multiple times if you remove and store it proper...
To recommend when Americans should wear face masks, the CDC determines an area’s Covid-19 Community Level risk on a scale of low, medium or high. To do so, it analyzes how many Covid-related hospital beds are in use, hospital admissions and the total number of new Covid cases in that area. Each Covid-19 Community Level corresponds to a masking recommendation — suggested precautions increase alongside the level. To determine your area’s Covid-19 Community Level, use the CDC's Covid-19 county check.
The CDC’s order requiring masks on public transportation and at transportation hubs is no longer in effect, and airlines no longer have mask mandates. However, the CDC says it “continues to recommend that people wear masks in indoor public transportation settings,” despite being unable to enforce any rules. Before you use a specific public transportation system in your area, be sure to double-check its mask requirements as they can change at any time.
