Crosstex Isofluid Procedure Masks deliver lightweight, fluid-resistant facial protection designed for clinical procedures where low levels of fluid, spray, and aerosols are generated. Engineered to meet ASTM Level 1 performance standards, these 3-ply pleated earloop masks feature a fluid-resistant outer spunbond layer, a meltblown filter media core providing high Bacterial Filtration Efficiency (BFE) and Particle Filtration Efficiency (PFE), and a soft, non-irritating inner tissue layer. Select models integrate proprietary Secure Fit Mask Technology—featuring malleable aluminum nose and chin wires to eliminate gaping along the facial perimeter—or an inner anti-fog strip to absorb condensation and prevent eyewear fogging.
