FFP2 vs N95 vs KN95: What Is the Difference?
Quick Answer
FFP2, N95 and KN95 are respirator standards from different regions that all filter at least 94 to 95% of fine airborne particles. The main differences are the region and test protocol, not a large gap in protection. FFP2 (Europe, EN 149) is tested with both salt and oil aerosols and specifies a total inward leakage limit; it also offers a reusable "R" class. N95 (United States, NIOSH) filters at least 95% of non-oil particles. KN95 (China, GB 2626) is broadly equivalent to N95.
Standards Compared
| Standard | Region / Test | Min filtration | Oil aerosol | Notes |
|---|---|---|---|---|
| FFP2 | Europe, EN 149 | ≥94% | Tested with salt and paraffin oil | Total inward leakage limit; NR or reusable R class |
| N95 | USA, NIOSH 42 CFR 84 | ≥95% (non-oil) | Not oil-resistant | Relies on fit for seal |
| KN95 | China, GB 2626 | ≥95% | Depends on KN vs KP grade | Broadly equivalent to N95 |
| KF94 | Korea, KMFDS | ≥94% | — | Korea standard |
Values are common thresholds for each standard; always defer to the latest national regulations and test reports.
Which Should You Choose?
- For European markets or tenders that reference EN standards, FFP2 is usually expected.
- For oil mist, kitchen smoke or industrial aerosols, choose a standard tested against oil particles, such as FFP2.
- If reusability matters, look for an EN 149 reusable "R" class product rather than a single-use item.
- Always match the certificate to the actual product and market, and request the test report. N95 and FFP2 are different certification systems, so buyers should evaluate the actual standard, test reports and intended application—not just the “95%” number.
Surgical Mask vs Respirator (FFP2 or N95)
Surgical masks mainly provide droplet and splash protection, while respirators such as FFP2 or N95 are designed to reduce inhalation of airborne particles.
The Key Difference: Fit
- A surgical mask usually fits loosely around the face.
- A respirator is designed to fit more closely around the: Nose · Cheeks · Chin

Frequently Asked Questions
Are FFP2 and N95 the same?
They are comparable in filtration but come from different standards and test protocols. FFP2 additionally specifies total inward leakage and a reusable class.
Is FFP2 better than N95?
Neither is simply better. Choose by market requirement, oil exposure and reusability.
Is KN95 as good as N95?
KN95 is broadly equivalent, but verify the certificate and test report of the specific product.
Which is best for oil mist?
A standard tested against oil aerosols, such as FFP2.
Can N95 or FFP2 Respirators Protect Against PM2.5?
Yes. A properly fitted N95 or FFP2 respirator can reduce exposure to PM2.5 and other fine airborne particles.
