The filter media is sewn into the middle layers of the mask and is not replaceable.
After usage, place the mask on a hook or surface for airing; do not store in any packaging while airing. Exposure to sunlight through a window will help to freshen the mask.
Hand wash by rinsing outer and inner layer with warm water. Add a drop of liquid soap and gently rub inner and outer layers. Rinse again and hang to fully dry.
Many Vogmask users wash the mask each 7 to 10 days to freshen.
