The use of face masks has become increasingly common in recent years, particularly during the COVID-19 pandemic.
Surgical face masks are a type of mask that is widely used in healthcare and construction industries.
They form a barrier between the wearer's face and the external environment, protecting against dust, pollen, respiratory and nasal secretions.
What is the different types of surgical face masks, namely Type I, Type II, and Type IIR, and explain their differences.
Surgical Face Mask Type I
Designed to stop the transfer of infection from the wearer to the external environment.
They have a bacterial filtering efficiency (BFE) of 95% and are effective in stopping the spread of respiratory and nasal secretions when the wearer exhales.
However, disposable masks type I do not offer much protection to the wearer from immunological agents.
Surgical Face Mask Type II
Type II masks have a BFE of 98% and are more effective than Type I masks.
They are designed to provide additional protection to the wearer against large aerosolized liquid particles and are commonly used in healthcare settings.
Surgical Face Mask Type IIR
These masks have the same BFE as Type II masks (98%) and also provide splash resistance.
Face masks Type IIR are designed to provide the highest level of protection to the wearer and the external environment and are commonly used in medical and surgical settings.
