KN95 vs KF94: What's the Difference?
If you've been shopping for high-filtration masks, you've likely come across both KN95 and KF94 options. Both are significantly more protective than cloth or surgical masks, but they come from different countries, follow different testing standards, and have distinct designs. Here's what you need to know.
What Is a KN95 Mask?
KN95 is China's equivalent of the American N95 standard. "N95" refers to filtering at least 95% of airborne particles. KN95 masks are regulated under the GB 2626-2019 standard and must pass filtration, breathability, and fit tests.
KN95 masks typically feature a cup or boat shape with ear loops, and are widely available in multiple sizes. Our lab-tested KN95 masks are independently verified to filter ≥99% of particles — exceeding the 95% minimum standard.
What Is a KF94 Mask?
KF94 is South Korea's high-filtration mask standard. "KF" stands for Korean Filter, and "94" means it filters at least 94% of particles. KF94 masks are regulated by the Ministry of Food and Drug Safety (MFDS) and are known for their distinctive "boat" or "bi-fold" shape that creates a large air pocket in front of the mouth.
Key Differences at a Glance
| Feature | KN95 | KF94 |
|---|---|---|
| Country of Standard | China | South Korea |
| Filtration Minimum | ≥95% | ≥94% |
| Regulating Body | GB 2626-2019 | Korean MFDS |
| Typical Shape | Cup / Boat / Flat-fold | Bi-fold "boat" shape |
| Ear Loops vs Headbands | Usually ear loops | Usually ear loops |
| Size Options | Multiple (XL to Kids) | Limited (Adult / Small) |
| Availability in US | Widely available | Less common |
Which Offers Better Protection?
In practice, both masks offer very similar levels of protection when worn correctly. The KN95 standard requires ≥95% filtration vs KF94's ≥94% — a negligible difference. What matters far more is fit. A mask that seals properly to your face will always outperform a higher-rated mask with gaps.
This is why size selection is so important. Our KN95 masks come in six sizes from XL to Kids, making it easier to achieve a proper seal for every face shape and size — something KF94 masks, with their limited sizing, often can't match.
Breathability and Comfort
KF94's boat shape creates more space between the mask and your mouth, which some wearers find more comfortable for extended use. KN95 masks vary by design — our KN95 masks with adjustable ear loops are designed for all-day comfort without sacrificing filtration.
Bottom Line
Both KN95 and KF94 masks are excellent choices for high-filtration protection. If you're in the US, KN95 masks are more widely available, come in more sizes, and are easier to verify through independent lab testing.
