While there are still many uncertainties surrounding the COVID-19 pandemic, there is one thing that remains indisputable: Masks play an important role in slowing the spread. At the start of the pandemic, cloth masks and disposable surgical masks were the face coverings of choice among the masses. But in the wake of the omicron variant's surge, the Centers for Disease Control and Prevention has now declared that KN95 and N95 masks are the best defense against COVID-19.

"These masks offer different levels of particle filtration," Chicago-based internal medicine physician Vivek Cherian, M.D., tells EatingWell, noting that it's the result of their multilayer construction and secure, face-hugging fit. "N95s and KN95s both filter 95% of airborne particles," he continues. "Regular surgical masks are not nearly as effective."

Aside from their multilayer filtration systems, N95 and KN95 masks further increase your protection against COVID-19 with their advanced design, which includes face-fitting edges that minimize your exposure by fully covering your nose, mouth and chin. Their signature duckbill shape offers a more spacious chamber that not only promotes more breathability, but also strategically directs your exhale away from you. Additionally, these masks typically have an adjustable nose bridge to enhance their fit and keep them from falling down and exposing your nose. Depending on the design, N95 and KN95 masks either have ear loops or secure straps that go around your head and ears.

With Cherian's guidelines, we've compiled a list of the best KN95 and N95 masks, each of which is featured on the FDA's Emergency Use Authorization List and will boost your defense against the coronavirus. Here are seven FDA-approved KN95 masks that you can buy:

What's the Difference Between KN95 and N95 Masks?

So, what's the difference between the two? Cherian explains that N95 masks are approved and regulated by the CDC's National Institute for Occupational Safety & Health, whereas KN95s are regulated by China (and don't have approval from NIOSH). He adds, "That being said, according to the CDC, KN95s are currently the most widely available respirator that also meets an international standard, and ultimately there's no question that KN95s offer more protection than surgical masks."

Other than those differences, they both filter at least 95% of airborne particles measuring 0.3 microns when you have a proper fit. Similarly, cloth masks can filter fine droplets less than 10 microns in size, but only when they're made with multiple layers of fabric, says the CDC. Note: The coronavirus measures approximately 0.1 microns and is usually bound to larger particles like droplets, but Cherian assures that both N95 and KN95 masks work for COVID-19-sized particles because they use electrostatic absorption to draw them in and they "move erratically throughout the mask as opposed to straight through, and this increases the chances of getting entrapped in the mask fibers." He adds, "Viruses usually are attached to droplets or aerosols, which [can] be generated from talking, coughing, breathing, etc., and can absolutely be collected by N95 masks quite efficiently."

How to Choose the Right Mask

Since they offer the highest level of protection, KN95 and N95 masks have been in high demand and shoppers have seen an influx in iterations, making it difficult to determine the best KN95 masks available. Only a handful of Chinese manufacturers have been approved by the U.S. Food and Drug Administration for emergency use, so when shopping, Cherian warns to be wary of counterfeit masks and to pay close attention to telling details like the markings on your chosen model.

"There's no foolproof way to spot a counterfeit KN95 mask, but one way to spot a counterfeit mask is to see if the company name has its stamp on the mask," he explains. "According to the CDC's website, to validate a KN95 mask, you want to ensure it is tested by an ISO/IEC 17025-accredited test lab specific to the country that holds the standard." Legitimate masks also have FDA-approved markings on the box or the mask itself, and certain brands now include an anti-counterfeit label to verify the masks' authenticity. Check the CDC's website to find verified KN95 and N95 mask brands and sellers for more peace of mind.

If you're unable to get your hands on masks due to stock shortages or shipping delays, Cherian notes that you can prolong the usage of your personal protective equipment. "It's important to realize that both N95 and KN95 masks can be reused as long as it's in a non-health care setting," he shares. "Now, if there's an accident and the mask gets wet or soiled, then you should not reuse the mask." Also worth noting, if your mask loses its shape, you should avoid reusing it since effectiveness also depends on having a proper fit, he adds.

However, if you don't have access to an N95 or KN95 mask, Cherian says that your next best option would be to use well-fitted surgical masks. He adds, "Remember: The worst thing you can do is to use a simple face cloth or even a face shield—there is actually no data to support face shields [being] at all effective." But if you're in a pinch, there are ways you can up your cloth mask's defense. While a new study from the CDC found cloth masks to only lower your odds of contracting the virus and testing positive by 56% (surgical masks lowered them by 66% and respirators lowered them by 83%), the organization shared that double masking a multilayered cloth mask with a disposable surgical mask can improve your protection against the virus. Make sure to wear the surgical underneath the cloth mask as this will push the edges of the surgical mask closer to your face and add more filtration.

Now that you're familiar with how KN95 and N95 masks work, keep scrolling to learn more about the best FDA- and NIOSH-approved options you can buy. Below, you'll also find the exact masks that Cherian uses to keep himself and his family safe.
