Customer Review

Reviewed in Australia on 13 October 2020
I use hand made surgical style masks that have a pocket for a filter. I use these filters in the pocket and they are great. I wear masks for 8-10 hours a day for work and find that when I use these inserts, the mask fabric is not wet after a few hours, as the excess moisture probably gets trapped in these filters.
