Coppermask Unveils a Brand-New, FDA-Approved and Fashionable Face Mask

The CM-KF94 face mask, which was developed and manufactured in Korea, is made more functional with its high-performance 4-layer air filter technology (exterior non-woven, center non-woven, melt-blown filter, inner fabric). This makes its filter efficiently collects fine dusts and microbes for up to 0.4um of fine particles in the air to prevent it from entering the body.

KF94 face masks, which means Korean Filter 94, is an equivalent of the medical grade face mask known as N95. CM-KF94 is FDA approved and was certified to provide 94% filtration efficacy. This means that CM-KF94 is medical grade and is safe to be worn even by front liners and in medical facilities such as hospitals and clinics

To further secure the level of safety when one wears the CM-KF94, CopperMask subjected this product to additional laboratory clinical tests. These tests proved that CM-KF94 has bacterial filtration efficacy up to 99.99% and was further tested for breathability and microbial cleanliness. Clearly, this is the safest CopperMask product one can get.
