KN95 vs N95: What's the Difference?
If you've been shopping for high-filtration masks, you've likely come across both KN95 and N95 options and wondered whether they're interchangeable. The short answer: they're very similar in protection level, but they follow different national standards and have some practical differences worth knowing. Here's a full breakdown.
What Is an N95 Mask?
N95 is the United States standard for respirator masks, regulated by the National Institute for Occupational Safety and Health (NIOSH) under the CDC. The "N" stands for "Not resistant to oil" and "95" means the mask filters at least 95% of airborne particles when properly fitted.
N95 masks are most commonly used in healthcare and industrial settings. They typically feature headband-style straps that loop over the head (rather than ear loops), which helps create a tighter seal. NIOSH-approved N95 masks undergo rigorous testing and approval before they can be sold in the US.
What Is a KN95 Mask?
KN95 is China's equivalent standard, regulated under GB 2626-2019. Like the N95, it requires filtering at least 95% of airborne particles. The key practical difference is that KN95 masks typically use ear loops rather than headbands, making them more comfortable and accessible for everyday use.
Our lab-tested KN95 masks are independently verified to filter ≥99% of particles — exceeding the 95% minimum — and are available in six sizes from XL to Kids for a proper, protective fit.
Key Differences at a Glance
| Feature | N95 | KN95 |
|---|---|---|
| Country of Standard | United States | China |
| Regulating Body | NIOSH / CDC | GB 2626-2019 |
| Filtration Minimum | ≥95% | ≥95% |
| Strap Style | Headbands | Ear loops |
| Size Options | Very limited | Multiple (XL to Kids) |
| Typical Use | Healthcare / industrial | Everyday / consumer |
| Availability | Limited, often prescription | Widely available |
Which Offers Better Protection?
In terms of filtration, N95 and KN95 masks are essentially equivalent — both filter at least 95% of airborne particles. The bigger factor in real-world protection is fit. A mask that seals properly to your face will always outperform a higher-rated mask worn with gaps.
This is where KN95 masks have a practical advantage for everyday consumers: they come in more sizes. Our masks are available in XL, Large, Medium, Small, XS, and Kids, so you can find a size that actually seals to your face. Use our Mask Size Guide to find your fit.
How to Tell If Your KN95 Is Legitimate
Unfortunately, counterfeit KN95 masks are common. Here's what to look for:
- Look for independent lab test results — reputable sellers publish these
- Check that the mask lists the GB 2626-2019 standard on the packaging
- Be wary of unusually low prices or masks with no country of origin listed
- Avoid masks that claim to be "NIOSH-approved KN95" — NIOSH only certifies N95s
All of our KN95 masks are independently lab tested, and we publish those results so you can verify the filtration performance yourself.
