Our KF94 MB (Melt-blown) filter is 1.2 metre (120 cm) wide and we can’t send continuous lengths unless you purchase a 20 metre roll. You can cut at least 15 filters from a half metre unit, subject to the size of filter you need and we highly recommend you change the filter at least twice a week as general public usage, more often if you are close to infected or vulnerable people. The filter is not washable, once you have used the filter, please put it in a bin and wash your hands and machine wash the mask.
