COGREEN NANO MASK

│ Strong Point │

● High efficiency

Dusts are just latched on the static charged fibers.	Fine dusts are filtered and collected by mechanical structure of nanofibers.

(The above images for N95 grade and Nano fiber are taken with SEM after 0.3㎛-sized dusts are pushed to flow each material under the same condition.)


Nanofibers Structure

More than a few billion pores in 1 inch²
-Smaller size of millions pores than a water droplet

molecule, this prevents the exhalation / inhalation of undesirables such as viruses, bacteria, dusts and other potential harmful materials from entering or exiting.
-These contaminated particles cannot penetrate these mechanically structured pores made with nanofibers.

Nanofibers vs Nano-particles

Nanofibers are quite different from nano-particles.
Unlike nano-particles, nanofibers are very thin continuous fibers and they do not or become a particle even if it is broken. Safe to use.

● Air permeability


Perfect forfiltration media
- To filter substances, consistent pressure on the flow should be applied.
- Billions of extremely fine pores do not slow down the flow, which means reducing pressure drop.
- This implies that it helps lower power generation cost for operating a fan to keep consistent pressure on the flow.

● Durability

Traditional Electrostatic Charged Mask	Nanofibered Mask

After discharging, traditional elecrostatic-charged mask has significant efficiency drop while for the nanofibered mask, efficiency drop is very little. Nanofibered mask has stable efficiency.
