Once surgical masks are made, they must be tested to ensure their safety in various situations. There are five tests they must be put throughBacteria filtration efficiency in vitro (BFE). This test works by shooting an aerosol with staphylococcus aureus bacteria at the mask at 28.3 liters per minute.

The filtration efficiency and protective ability of a medical face mask is compromised when the mask becomes wet, torn or dislodged. Generally speaking, the higher protection value of a mask the longer it will maintain filtration; however, there is no set rule for how long a mask should be worn as it depends on humidity levels, respiration rate, nasal discharge, talking, etc.

Pulmonary Function Test. Many times a respirator fit test is done along with a Pulmonary Function Test (PFT), also known as a Spirometry. Whereas the respirator fit testing ensures the mask worn is the right fit and model for the employee, the pulmonary function test actually gauges the employees lung health.
Facemasks and N95 respirators are examples of personal protective equipment that are used to protect the wearer from liquid and airborne particles contaminating the face. They are one part of an
