Testing has shown that ViralOff
remains fully effective for at least 30 washes. After 30 washes the treatment
may begin to lose effectiveness and slowly become more susceptible to surface
contamination. It is for this reason we recommend not washing the mask unless
it is noticeably soiled. It is important to note that the mask itself does not
rely on the Polygiene ViralOff treatment for filtration and will remain
effective as long as the mask is not visibly damaged. This means that your mask
still works after 30 washes, but you now will need to take the same precautions
that you do with any mask that is not finished with Polygiene ViralOff.
