For mask particle filtration testing, we sought to approximate the testing guidelines of the new ATSM Standard Specification for Barrier Face Coverings (ASTM F3502-21). The specification establishes performance standards for reusable, barrier masks worn by the general public. Particle filtration testing was performed on a complete mask using a TSI PortaCount 8038 Respirator Fit Tester. This device is able to measure a combination of both fit and filtration testing over a particle range of 0.2 µm to 1.0 µm, in the aerosol particle range. The measured particle filtration level for the combination of face fit and filter material for the VocalEase Mask varied between 62-67%. This is above the Level 2 performance standard (the higher of two levels) of the ASTM specification.
