The KC Mask VBF 99.9 is the only reusable face mask on the market designed to protect you and those around you from viruses and bacteria through the use of specially developed, laboratory-tested virus filters (not FFP dust filters like other face masks). These filters have also been tested in Nelson Laboratories for viral and bacterial filtration efficiency at increased challenge level and proven to be 99.9% efficient for viral filtration and 99.98 % efficient for bacterial filtration.
The KC Mask is made of soft, flexible, skin-safe medical materials similar to silicone, which ensure the mask holds fast and hugs the contours of the face. Four adjustable straps allow the mask to adapt to different head sizes and shapes, ensuring the mask can be worn comfortably and safely for extended periods of time.
To minimise the risk of infection, the mask has no exhalation valves, meaning it filters air both on inhalation and exhalation.
