AirPOP Pocket Face Mask 2 Pieces (Black) To provide you with the best possible protection, we have reinvented the entire filtration process. We developed the mask from the ground up, focusing on efficiency, comfort, and ease of breathing. What we have achieved is a breath of fresh air. Four-Layer Protection The two-layer electrostatic meltblown fabric filters feature high filtration efficiency and protect against even the finest impurities. The pre-filter layer is located between two protective outer layers, effectively trapping harmful airborne particles. The filter blocks over 98%. Fit Every face is different. That’s why our Ergo Foam has a special shape that fills the hard-to-seal area around the back of the nose. The pocket mask opens wide and, thanks to its foldable wings, provides better coverage for the cheeks and chin. The AirPop fits your face perfectly.
