For your face mask, you can use our special filter fleece made by a well-known German manufacturer of non-woven fabrics as an additional textile barrier. This increases the filtering effect of the face mask without decreasing the wearing comfort.
Our inserted filter fleece is also being used in the manufacturing of professional protective masks. The composite non-woven fabric has been tested in an independent laboratory and has shown very good filter performance, which increases the protection of others.
To be sure which size of filter media you need for your face mask, you can take a look at the loops of the mask. The size of the mask is marked with three, two or one hole on the left loop.
For a face mask with size one and therefore one hole on the loop, you need the filter fleece in size one.
For a face mask with size two and therefore two holes on the loop, you need the filter fleece in size two.
For a face mask with size three and therefore three holes on the loop, you need the filter fleece in size three.
The filter fleece must be removed before washing the face mask.
