A surgical face mask is a disposable face mask worn over the nose and mouth to help protect against the inhalation of airborne particles and to help prevent the spread of unhealthy airborne particles. Surgical Masks are tested against their Bacteria Filtration Efficiency (BFE), Particular-Filtration Efficiency (PFE), Fluid Resistance Penetration (mmHg), and Breathability (Delta P).
Unlike other cloth face coverings, a medical face mask is very carefully designed and manufactured to ensure that it remains effective at the prevention of spreading disease but not of minimizing any respiratory distress a person may feel due to heavy pollution in the air.
Unlike general 3 Ply Face Masks, Surgical Masks are protective for General Public, Vulnerable Individuals, Medical and Health Care Workers, as well as Front Line Workers.
These masks help block out most (if not all) large-particle droplets, splashes, sprays, or splatter that may contain viruses and bacteria.
