1 Introduction to Highly Efficient Nano - Mask

1. Nano? Nano is a unit prefix meaning one billionth.

2 1. Nano? Nano is a unit prefix meaning one billionth. Used primarily with the metric system, this prefix denotes a factor of 10 9 or It is frequently encountered in science and electronics for prefixing units of time and length. The prefix is derived from the Greek νᾶνος, meaning "dwarf", and was officially confirmed as standard in A hair Pollen Red Blood Cell

6 2. Nano fiber and Nano filter How nanofibers are produced Unlike conventional spinning methods to produce normal-sized fibers, nanofibers are produced by interfacial polymerization and electrospinning. With sufficiently high voltage, a charged liquid get is formed. The jet is elongated by a whipping processed caused by electrostatic repulsion. The elongation of the fiber leads to the formation of uniform fibers with nanometer-scale diameters.

Strong point of CoGreen Mask 1) High efficiency Traditional mask (N95 grade) Nano Mask FIBER: 3000nm FIBER: nm x 5,000 times Dusts are just latched on the static charged fibers. x 5,000 times 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 μm -sized dusts are pushed to flow each material under the same condition.)

4. Strong point of CoGreen Mask 1) High efficiency Water drop Nano web Nanofibers Structure More than a few billion pores in 1 inch² - Smaller size of millions pores than a water

molecule, this prevents the exhalation/inhalation of undesirables such as viruses, bacteria, dusts and other potential harmful materials from entering or exiting.

11 4. Strong point of CoGreen Mask 1) High efficiency Water drop Nano web Nanofibers Structure More than a few billion pores in 1 inch² - Smaller size of millions pores than a water droplet Air, Moisture Vapor Fine Dust, Bacteria etc. 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 nanoparticles. 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 Nanofiber Nano-particle

Billions of extremely fine pores do not slow down the flow, which means reducing pressure

12 4. Strong point of CoGreen Mask 2) 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 o perating a fan to keep consistent pressure on the flow.
