Size S - approx. 14,5 - 14,99 cm - teenagers, adults

Mask care: The mask should not be worn for longer than 3 hours. It is necessary to sterilize it in a boiling water or by ironing every day.
Thanks to the silver, the filters can be used for up to 5 days, but it is necessary to sterilize them every day, using desinfection or by ironing at the lowest degree. The material can be sterilized with an alcohol-based disinfectant only, without additional additives. Otherwise, it could cause clogging of the fibers, and deterioration of the filtration properties could occur. The filters must not be washed. The Face Masks and Filters cannot be returned or replaced from hygienic reasons.
