Product Features Include:

• Has a lower delta P, a measurement sought by clinicians performing longer surgical procedures
• Lightweight, three-layer construction
• Filtration efficiency: BFE1 =99%[1], PFE2 =99%[2]
• [1] BFE = Bacterial Filtration Efficiency
• [2] PFE = Particulate Filtration Efficiency meets the new classification system for mask standards STM F2100-04. PFE test results are provided for comparing
• performance of surgical masks under similar laboratory conditions. This does not reflect expected levels of filtration in actual use conditions nor replace the need to use NIOSH certified respirators if exposed to hazardous airborne contaminants
