Adult surgical mask

box of 50sky bluewhite

Thicknesses for optimal filtration Each side of the mask has an elastic band allowing the mask to be fixed on the face. A metal nose clip covered with plastic allows the mask to be adjusted on the face at the level of the nose. Extremely light and comfortable. When a person breathes, speaks, coughs, sneezes, etc., he rejects, in greater or lesser quantity, droplets secreted by the mucous membranes of the mouth and nose. These droplets evaporate quickly and leave particles suspended in the air. The majority of these particles have a diameter of between 0.5 μm and 12 μm; larger droplets, in particular, may contain microorganisms originating from the source site. The particles they contain can then spread through the air to a sensitive site, such as an open wound from an operation or sterile equipment. Surgical masks intended for use in operating rooms and healthcare facilities with similar requirements are designed to protect the working environment, not the mask wearer. • Note that this product obtained a bacterial filtration efficiency (BFE) > 98%. • Outer side : outerlayer Weight: 25g/m2 ±2g/m2 • Filter: filter layer met blown Weight: 25g/m2 ±2g/m2 • Inner side : Inner layer Weight: 25g/m2 ±2g/m2 Sizes: One size
