Layer – 1: Which is water repelling layer, and it will not allow to enter any aerosol/mist to be penetrated, as major respiratory viral diseases are spread through the sneezing and coughing by the infected person.
Layer – 2: Contains very high salt concentration. If any microbe is able to penetrate through Layer-1, then it will come in contact of salts, which will absorb all the water from the microorganism and will inactivate.
Layer – 3: Contains Vitamin-E and Cur cumin from Turmeric. The Enveloped virus and bacteria which contains lipid bi-layer at their periphery which is oily in nature. Vitamin – E being oily in nature will enable hydrophobic adsorption of the microbes, and it will kill/inactivate them based on antioxidant activity of Vitamin-E. Additionally it contains dissolved Cur cumin, which possess broad spectrum anti-bacterial and anti-viral activity, which will again ensure killing of the microbes.
Layer – 4 & 5: These are similar to Layer 1 and 2. When infected person wears the mask, layer 5 and 4 will not allow aerosol/sneeze/mist of the infected person to pass through the barrier.
In addition to filtration, this mask works on the principle of Filtration + Adsorption + Killing/inactivation of the contacting microbes, while normal masks like N95 works only on the principle of filtration of microbes.
