Our facemasks are with one layer of fabric and a four-layer synthetic fiber layer on the inside. The fiber layer has a filtering function comparable to that of a dust filter in a vacuum-cleaner.
To make it easier to breath, the masks are constructed to keep free of your mouth and nose.
The mask has a nose clip to hold in place and two elastic bands to go around the ears.
The mask is reusable as it can be washed up to 60˚C / No steam ironing.
