  • How to use Shilma masks

    The Shilma™ mask can be used comfortably enough all day long, at school, at work, in cafes, restaurants and even during sports. The mask is available in many styles:

    • Shilma™ for sunglasses or eyeglasses;
    • Shilma™ with a special designed frame;
    • Shilma™ with elastic thread.

    While the regular masks direct most air upwards (straight into the path of the eyeglasses), the Shilma™ mask conveniently steers the air towards the lower body. This significantly reduces the spread of germs and, also, the fogging of eyeglasses.
