2017/09/27Respiratory protective devices (RPDs), utilizing particle filtration systems, are required to protect the respiratory tract of workers exposed to harmful bioaerosols. Nonwoven filters, which are the basic material used in RPDs, must have a high capacity to capture fine particles dispersed in the air and be able to provide antimicrobial activity throughout the lifetime of the equipment [ 1, 2 Get price

IJERPH

Bioaerosols are common biological factors in work environments, which require routine use of filtering respiratory protective devices (FRPDs). Currently, no studies link humidity changes in the filter materials of such devices, during use, with microorganism survivability. Our aim was to determine the microclimate inside FRPDs, by simulating breathing, and to evaluate microorganism Get price

Polymers

Particulate matter (PM) and airborne viruses bring adverse influence on human health. As the most feasible way to prevent inhalation of these pollutants, face masks with excellent filtration efficiency and low press drop are in urgent demand. In this study, we report a novel methodology for producing high performance air filter by combining melt blown technique with corona charging treatment Get price

Examination of Nanoparticle Filtration by Filtering Facepiece

2021/04/06The onset of the COVID-19 pandemic in spring 2020 resulted in a spike in the demand for face masks and respirators. Due to their effectiveness at filtering aerosols that could potentially contain viruses, the N95-type filtering facepiece respirators (FFRs) are frequently used by healthcare workers and first responders. However, due to a shortage of domestic N95 FFRs in the US at the beginning Get price

Time

Abstract Previous studies on nonwovens used for respiratory protective devices (RPDs) were related to equipment intended for short-term use. There is only limited research on the development of biocidal nonwoven fabrics for reusable RPDs that could be used safely in an industrial work environment where there is a risk of microbial growth.
