What Is KN95 / FFP2 Respirator Masks?
KN95 (and equivalent FFP2) respirator masks are cup or fold flat facepieces with electrostatically charged filter media that capture at least 95% of non-oil airborne particles, used for dust, haze and droplet protection.
Key Takeaways
- KN95 filters at least 95% of non-oil particulate at the rated flow.
- Electret melt-blown media gives high capture at low breathing resistance.
- A nose clip and head straps give a secure facial seal.
- Supplied with GB2626 / EN149 marking for regulated use.

How to Select the Right KN95 / FFP2 Respirator Masks
- Confirm standard (KN95 GB2626 or FFP2 EN149) for your market.
- Choose cup or fold-flat by wearer comfort and storage.
- Check nose clip and strap fit for a secure seal.
- Order boxed or private-label with your brand.
Typical Applications
- Construction and workshop dust
- Haze and urban pollution
- Healthcare and lab support
- General public respiratory protection
Frequently Asked Questions
What does KN95 filter?
At least 95% of non-oil airborne particles at the rated flow, using electrostatically charged melt-blown media.
KN95 vs FFP2 - what is the difference?
They are equivalent performance grades under different standards: KN95 is GB2626 (China), FFP2 is EN149 (Europe).
Materials & Chemistry
- Super absorbent polymer (SAP) - sodium polyacrylate that gels many times its weight in fluid, the core of modern absorbency.
- Fluff pulp - bleached wood pulp that gives pads structure and carries fluid to the SAP core.
- Spun-bond polypropylene - a soft, breathable non-woven used for the skin-contact top sheet.
- Cast polyethylene (CPE) - a fluid-repellent film used for isolation gowns and aprons.
- Melt-blown polypropylene - the electret filter media inside KN95 / FFP2 respirators.
Standards & Compliance
- ISO 13485 - the quality-management system for medical-device manufacturing.
- ISO 9001 - the general quality-management baseline for consumables supply.
- FDA 21 CFR - the US market clearance path for devices and PPE.
- EU 2016/425 - the European personal-protective-equipment regulation covering gowns and masks.
- EN 14683 - the European standard for medical face masks; AAMI PB70 for gown liquid-barrier levels.
- GB 2626 - the Chinese KN95 respirator standard; EN 149 the European FFP2 equivalent.
Buyer's Guide & Common Mistakes
- For gowns, match the AAMI liquid-barrier level to the procedure's fluid-exposure risk.
- For masks, confirm the KN95 (GB 2626) or FFP2 (EN 149) standard required in your market.
- Request latex-free options for sensitive-skin users and allergy-prone settings.
- Private-label under ISO 13485 control with your own brand, sizing and packaging.

Engineering & Evaluation Notes
Disposable medical products live or fail on the absorbent core: super absorbent polymer (SAP) gelled with fluff pulp sets capacity and skin dryness, while the non-woven top sheet and leak-proof backsheet set comfort and containment. Supply under ISO 13485 with the right standard - AAMI PB70 for gowns, EN 14683 or GB 2626 and EN 149 for masks - and private-label OEM lets distributors sell under their own brand with consistent quality.
