Infused Copper

Copper has long been used throughout history for its anti-bacteria properties, and since 2008, the U.S. Environmental Protection Agency has officially certified that Copper Alloys as antimicrobial public health materials.

SOTERTEX has introduced the technology to apply infused copper on the fabric, capable of immobilizing bacteria, common viruses and other harmful substances. Together with the multi-layer structure, our Copper+ face cover serves as an effective barrier, and provide a better protection to wearer.

Water Repellent

A cough can generate 3,000 potentially infectious droplets, which can hit a mask's fabric at a speed of 130 mph. Therefore, a mask that is made with water repellent fabric will provide more effective defence.

SOTERTEX Copper+ has applied a Water Repellent coating and the function can be maintain up to 60 times hand wash safeguarding the wearer.
