Nano95 3-layers respiratory mask

Nano 95 3-layers respiratory masks in terms of appearance are similar to surgical masks and in terms of efficiency and pressure drop are similar to FFP2 and N95 masks. These masks contain a nanofiber layer between the layers of their protective spun bond. These masks have the efficiency of 95% for trapping 2.5 microns particles and pressure drop of about 43 pascal (also known as breathability).
The figure below shows the efficiency diagram and pressure drop of Nano 95 3-layers respiratory masks.
