More Information
Summary:A filter or mask structure, comprising a first face layer comprising a polymer and having a face basis weight, a second outer layer comprising a polymer and having an outer basis weight less than 34 gsm, and a third outer layer comprising a polymer and having a third basis weight and disposed between the first face layer and the second outer layer. At least one of the layers further comprises an AM/AV compound. The mask structure demonstrates an Escherichia coli efficacy log reduction greater than 4.0, as measured in accordance with ASTM E3160 (2018) and a particulate filtration efficiency greater than 90%, as measured in accordance with ASTM F2299-03R17.
