Assessment of the filtration efficiency and antibacterial activity of reusable antibacterial face masks after washing
This study evaluated the filtration efficiency, and continuity of the antibacterial activity of reusable antibacterial silver, copper, and graphene antibacterial masks before and after washing. The masks were washed at three different temperatures (40 °C, 60 °C, 90 °C) and up to 10 washing cycles. The filtration efficiencies of the three reusable antibacterial masks were between 10 and 13% before washing and increased by approximately 6% after washing. Before washing, the bacterial filtration efficiency was between 93 and 98%. The antibacterial activity was 98% for both the silver and copper masks, and 88% for the graphene mask. All these values were higher than those of non-antibacterial masks. There were no trends in performance difference with increasing washing temperature or cycles, and performance did not change significantly compared to before washing, regardless of the temperature or washing cycles. Under certain testing conditions, the bacterial filtration efficiency of the three reusable antibacterial masks was < 95%, indicating that they might not be able to block effectively bacterial particles. Therefore, in the context of public health, the use of certified masks in daily life is strongly advised to ensure effective respiratory protection for the respiratory system and to mitigate potential health risks from aerosols and bioaerosols.
期刊介绍:
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
