    Antimicrobial barriers are fundamental for controlling infection caused by air borne microorganisms. Hence every individual should use such respiratory protection barriers with active anti microbial layer. Currently we have explored the development of antimicrobial layer that can kill bacteria by contact inhibition that can be used on microbial barriers. This study involves preparation of Montmorillonite (MMT) and chitosan solution incorporated with silver and copper ions. This is coated onto the middle layer (polypropylene) of the face mask which can destroy the microorganisms trapped in the mask. Different concentrations of this solution are coated onto polypropylene and its antimicrobial activity is checked by American society for testing and materials. The surface characterization studies were carried out using scanning electron microscope (SEM) and Energy dispersive x-ray analysis (EDAX). Bacterial filtration efficiency testing and ASTEM E2149 for evaluation of anti microbial activity was performed and it was observed that 10% Ag-Cu incorporated MMT coated over polypropylene showed the highest anti microbial efficiency of 99.99%. The present study also revealed 10% Ag-Cu incorporated MMT mask can be used as a potential anti microbial barrier against air borne micro organisms.
