Our mask is shielded with infused copper ions in non-woven fabric. The powerful effect of copper ions on the whole outer surface of mask maintaining 99.9% free of bacteria and virus. KOPPER+ non-woven mask is an unprecedented quality mask, and it's Made in Korea.

KOPPER+ Non-Woven Mask

Much More than Just Protection

The mask prevents the individual from inhaling the virus, but the virus stays attached to the surface of the mask and it can also multiply with the presence of the host (bacteria). The mask surface in this case is acting as a reservoir of viruses and you are basically bringing all of them to your house. 
If you touch your family with a hand that touches a mask contaminated with a virus, the consequences will be hard to imagine. Viruses will also spread to all surrounding areas such as handles, railings, and furniture. 
WHO is also urging you not to touch the mask, take off the mask strap and throw it away in an airtight can, outside the house, before entering the house. In particular, children are said to touch close to hundreds of times a day, touch their mouths and noses again with their hands, and constantly smear the virus practically to everything around them.
With our KOPPER+ non-woven mask, As soon as the virus lands on the mask, it undergoes an inactivation process, and it was confirmed that 99.9% of the virus was killed within 30 minutes (minimum test time). Masks protect individuals from viruses, but in order to prevent the spread of viruses, masks that destroy viruses as soon as they come into contact must be widely available.

-> KFDA approved KF80, KF94, KF99 as well as FDA approved N95, N99...etc. masks are with the filter efficiency certifications that are determined by the percentage of particles that are filtered through 0.4 μm to 0.6 μm particles. These certified masks are a mask for filtering out fine particles such as ultrafine dust. A novel invention, the KOPPER+ non-woven mask is a specially designed mask for blocking/killing viruses. The virus inactivating effect of KOPPER+ non-woven masks has been confirmed through tests of the specialized research institute. However, there is not yet a nationally recognized certification system that certifies the efficiency of killing viruses worldwide. 

2. Is the color of the mask usually light brown?

-> Our mask contains copper ions, so that is the reason why the antimicrobial copper is shining on the surface of the mask.
