With 95% filtration efficiency, the KN95 5-Layer Protective Face Mask blocks particles down to 0.3 microns. Five distinct material layers stop PM2.5 pollutants from entering the respiratory tract. Adjusting the metal nose clip creates a physical seal against road dust and urban smog.
Key Features
- 95% Filtration Efficiency: Filters 95% of 0.3-micron airborne particles. Stops fine dust from entering the lungs.
- 5-Layer Protection System: Combines non-woven and melt-blown fabric layers. Prevents heavy sweat and humidity from compromising the inner filter.
- Adjustable Nose Clip: A malleable bridge strip sits inside the top edge. Seals gaps around the nose to stop glasses from fogging.
- GB2626-2019 Standard: Meets specific respiratory protection requirements through standardized testing. Verifies performance against non-oily particulate matter.
Frequently Asked Questions
What is the difference between N95 and KN95?
KN95 masks meet the Chinese GB2626-2019 standard, while N95 meets US NIOSH standards. Both require at least 95% filtration efficiency against 0.3-micron non-oily particles.
Can KN95 masks be reused?
Reusing these masks degrades the electrostatic charge in the melt-blown layer. Discard the mask if it becomes damp from humidity or visible dirt.
