Particulate Filtration Efficiency (PFE) The super high Particulate Filtration Efficiency (PFE) material filters >99% of particles greater than 0.1 microns. When securely fitted, the mask helps to provide an effective barrier to particulate matter from laser plumes and electrocautery procedures. Breathability (Delta P) The mask design provides excellent breathability and low delta P (≤2.8) ensuring coolness and comfort even when worn for an extended period. Fluid Resistance The Super Fluid Resistant four-layer design provides optimum fluid resistance (160mmHg) thus minimising the risk of infection through strikethrough.
