Using a Gas Liquid Porometer to Reliably Measure Pore Size and Distribution for Filter Media Used in Face Masks

Surgical masks and respirators are typically made of nonwoven polypropylene fabric and mostly consist of three (or more) layers. The first and third layers are generally spunbond, while the middle layer is meltblown. This composition is commonly referred to as SMS technology (Spunbond/Meltblown/Spunbond). Three layers of respirator fabric While the efficiency of face masks is measured by ...
