    Masks Standard CLK Medical Supply

    ASTM specifies testing with a droplet size of 3.0 microns containing Staph. aureus (average size 0.6 0.8 microns). In order to be called a medical/surgical mask, a minimum 95% filtration rate is required. Moderate and high protection masks have bacterial filtration rates of 98% to greater than 99%.

    Surgical mask filter and fit performance ScienceDirect

    Most of the experimental mask filters were reported to have bacterial or particle filter efficiency greater than 96% . The smallest differences between NIOSH test results from this study and manufacturer reported filter efficiencies were found for mask D with a 94% NIOSH test efficiency and a >99

    The Basics of Surgical Mask Selection Infection Control

    BFE (Bacterial Filtration Efficiency) measures the percent efficiency at which the face mask filters bacteria passing through the mask. PFE (Particulate Filtration Efficiency) measures the percent efficiency at which the face mask filters particulate matter passing through the mask.

    2 Characteristics of Respirators and Medical Masks

    The Association of Perioperative Registered Nurses suggests that surgical masks should filter bacteria at least 0.3 µm in size for regular use and 0.1 µm in size for use in laser surgery, or they should provide 90 percent to 95 percent bacterial filtration efficiency (AORN, 2005).

    Assessment of Fabric Masks as Alternatives to Standard

    Apr 17, 2020 between 38% and 96% of this baseline. As has been previously observed by Cooper et al. (1983), adding a layer of nylon stocking over the masks minimized the flow of air around the edges of the masks and improved particle filtration efficiency for all masks, including all commercial products tested
