The Covid-19 pandemic has causes an increase in the amount of medical mask waste, and an alternative that can be done to reduce waste is using cloth masks with additional mask filters. The purpose of this research is to know the effectiveness of cloth masks with activated carbon filters in reducing pathogenic and increasing users’ comfort level when using the mask. This research method was experimental research. The research design was a completely randomized design (CRD) with one treatment in the form of concentration variations activator of KMNO4, which are 5%, 10%, and 15%. Bacterial Filtration Efficiency and Pressure Drop test data were analyzed by using one-way ANOVA on SPSS series 24 software and ImageJ software for the SEM test. The result of this research shows there is no significant (P value > 0,05) difference in each activator concentration variation. The activator with 15% concentration sample has the highest efficiency in filtering bacteria, which is 37.5%. The result of the pressure drop is there was no significant (P value > 0,05) difference between the three mask samples and the activator with 5% concentration sample is a mask sample with a mean of 3.675 mmH2O/cm2 (< 4.08 mmH2O/cm2). Based on the results of the study, cloth masks with activated carbon filter are considered less effective in reducing bacteria with a percentage of filtration ability below the ASTFM F2101-14 standard of 95%, and only mask with 5% concentration are comfortable enough to use, due to having a value below the EN14683 standard: 2019 which is < 4.08 mmH2O/cm2 © 2024 American Institute of Physics Inc..
