Bacterial Filtration Efficiency (BFE) Final Report
Test Article: Sample 1
Test facility: Nelson Laboratories, LLC6280S.
Salt Lake City, Utah 84123, United States
Test Procedure: Standard Test Protocol (STP) Number: STP0004 Rev 18
Abstract: The BFE test is performed to determine the filtration efficiency of the test items through comparison.
The bacterial control count is upstream of the test article and the bacterial count is downstream.
Use a sprayer to atomize S. aureus and deliver it to the test item at a constant speed
Flow and fixed air pressure. Challenge passes remain at 1.7-3.0 x 10 colony formation
The unit (CFU), the average particle size (MPS) is 3.0 # 0. At 3 um, the aerosol was collected through a six-stage, viable pellet, andersen sampler. This test method complies with ASTM F2101-19 and EN 14683: 2019. Annex B meets the acceptance criteria for all test methods. Tested in compliance with US FDA Manufacturing Practices (GMP) regulations 21 CFR Parts 210, 211 and 820

Filter mask helps decrease the transmission of flu & coronavirus/COVID-19. The product is Non-woven fabric such as ultrasonic heating, spot welding and banding with processes, Cellulose and paper / plastic-coated carbon steel, Disposable. Air permeability, Hypoallergenic. They are able to block dust and it will not cause tension or anaphylactic reaction for long-term wearing. Smooth cloth is adopted to reduce the falloff of fabrics, which is wash-free, maintenance-free, convenient, practical, safer and more healthful.
