As a result of the Canadian wildfires, the air quality on the East Coast is currently among the world’s worst, rivaling that of New Delhi, India. New York City’s air quality index (AQI) surpassed 200 last week, a level considered “very unhealthy” according to air purifier brand IQ Air.

According to the World Health Organization (WHO), “air pollution is one of the greatest environmental risks to health.” CNN points out that wildfire smoke is filled with PM2.5, the minute particulate matter that’s extremely dangerous and “can travel deep into lung tissue and enter the bloodstream” when inhaled. The pollutant is linked to respiratory illnesses such as asthma and heart disease.

Though statewide coronavirus mask mandates have expired, many people have opted to continue wearing them to keep germs and other airborne viruses at bay. And with face masks now a part of our everyday life, many Americans are also using KN95, N95 and KF94 masks to protect their health against tiny pollutants in smoke (such as in New York as a result of the Canadian wildfires), smog and more.
Before you restock your mask supply, you’ll want to know the differences among the three most common types of respirators being used to protect against pollutants and airborne viruses. Keep reading for more on where to buy real KN95, N95 and KF94 masks, how to spot fake ones and more.
What’s the Difference Between Face Masks and Respirators?
According to a 2021 Geohealth study, “face masks and respirators, with their ability to filter out a fraction of particulate matter, may offer a means to reduce exposure to PM2.5 and thus reduce the associated risk of acute respiratory outcomes.”
The Centers for Disease Control and Prevention previously recommended that people set aside fabric face coverings and upgrade to medical-grade protective masks to better safeguard against particulate matter. Surgical face masks (the pleated disposable three-ply masks used by medical professionals) are still the first line of defense to help stop the spread of the virus, but KN95, N95 and KF94 masks (also called air purifying respirators) are also recommended by the CDC to protect against pollutants in smoke.
The U.S. agency notes that “a respirator has better filtration, and if worn properly the whole time it is in use, can provide a higher level of protection than a cloth or procedural mask.” They also state that if N95, KN95 or KF94 masks are unavailable, then a cloth mask is still better than none at all.
KN95 vs. N95 vs. KF94 Masks: What’s the Difference?
The National Institute of Occupational Safety and Health (NIOSH), the agency that tests and approves air respirators for workplace use, has a list of approved particulate filtering respirators, according to the CDC. These NIOSH-approved air-purifying respirators protect by filtering particles out of the air while the user is breathing.
There are seven classes of filters for NIOSH-approved filtering face respirators available right now. The minimal level of filtration approved by NIOSH is 95 percent. The N, R and P designations refer to the filter’s oil resistance.
Here are the main differences among KN95, N95 and KF94 masks, which all filter out particles as small as 0.3 microns:
N95 masks are approved by NIOSH and filter 95 percent of airborne particles. They are not resistant to oil. The surgical N95 is a NIOSH-approved N95 respirator that has also been cleared by the Food and Drug Administration as a surgical mask.
KN95 masks are the Chinese equivalent of N95 masks and meet international safety standards. They are not NIOSH-approved, but they do filter out 95 percent of particles. Some manufacturers were granted emergency use authorization by the FDA when N95 masks were hard to find, but note that some brands have since had their approval revoked.
KF94 masks meet South Korea’s safety standards and filter 94 percent of particles. They are meant to give you a snug fit. Some KF94s are FDA-approved, and it’s important to check that the face mask was manufactured in South Korea.
How to Tell if Your Mask Is Authentic
It’s important to make sure you don’t purchase a counterfeit mask, especially from online marketplaces that don’t verify authenticity. You can tell N95 masks are authentic if they have a GB number, which tells you when the mask was constructed. No GB marking indicates it’s not a certified medical-grade mask. And, there is also no such thing as a kids N95 mask, since NIOSH approves adult-only masks. Brands do however create masks sized for children and others that give you extra comfort.
Since KN95 and KF94 masks are not approved by NIOSH, a tell-tale sign that they’re fake is if they’re stamped with “NIOSH-approved.”
The FDA also states that it “does not issue any type of device registration certificates to medical device facilities,” and that also applies to face masks. Therefore, if a mask’s description notes that the item is “FDA registered or “FDA listed,” that means the manufacturer has simply listed or registered the product but that it isn’t necessarily “approved” or “authorized” by the agency.
Overall, your best bet for ensuring that a face mask or respirator is effective or approved by a government agency is by choosing one that is on the NIOSH Certified Equipment List or the FDA’s database of approved medical devices.
