A Comparison of Surgical mask And N95 masks

2020-06-16 16:28
        Surgical mask:Surgical mask has good filtration effect on bacteria and viruses,breathable,comfortable and clean,and is widely used by modern doctors.The surgical mask is subdivided into three types according to its usage:disposable surgical mask,surgical mask and medical protective mask.Disposable surgical mask is suitable for wearing and blocking the exhalation or ejection of pollutants in the oral cavity and nasal cavity in the general medical environment.Medical surgical mask is suitable for disposable mask worn by clinical medical personnel during invasive operation(this kind of mask is generally divided into three layers:internal water absorption layer,intermediate filtration layer and outer waterproof layer);Medical respirator is suitable for the medical working environment,filtering the particulate matter in the air,blocking droplets,blood,body fluids,secretions and other self-absorption filter medical respirator.
  Surgical face masks are made with non-woven fabric,which has better bacteria filtration and air permeability while remaining less slippery than woven cloth.The material most commonly used to make them is polypropylene,either 20 or 25 grams per square meter(gsm)in density.Masks can also be made of polystyrene,polycarbonate,polyethylene,or polyester.
  N95 masks:N95 masks is a particulate-filtering facepiece respirator that meets the U.S.National Institute for Occupational Safety and Health(NIOSH)N95 classification of air filtration,meaning that it filters at least 95%of airborne particles.This standard does not require that the respirator be resistant to oil;another standard,P95,adds that requirement.The N95 type is the most common particulate-filtering facepiece respirator.
  N95 masks are very efficient as they filter air pollutants easily.95%of air pollutants can be easily filtered through these masks but according to the doctors,people who are suffering from respiratory diseases should not use these masks as they have to face serious consequences.N95 masks sometimes make difficult to breathe.Children should not use N95 masks.These masks do not provide full security in coronavirus.You can feel difficult to breathe in N95 masks and full security is also not guaranteed.
