This is a Filter for a diving face mask which is very common, at least in Germany.

Its a full face mask which can be update with this filter. The idea is to increase the safety by adding multiple layers of filter material depending on the filter quality which is available.
The mask is called subea easybreath.
(i´m no employee of subea and not connected to the firm or any shop that sells these face mask, so please don´t contact me to get the mask)
And please don´tbuy the masks just for personel use, I think it should be used for medical personel which hasn´t other material to protect themselves, be reasonable and don´t hort the masks)
With this Filter you can upgrade it to a FFP2 or FFP3 mask, ideal for hospitals which have not enough Face protection mask for the personel.
Just cut the filter material to circles 10cm in diameter and place one under each filter holder and fix them with rubber bands to the filter holder. There is a groove and a edge on each part which fit togehther to seal each filter layer.
The filter can be pressed easily on the adapter for the snorkel and replaces it. The mask has a rubber sealing ring in position which seals the filter.
I hope that helps fighting the pandemic.
