N95 Face Masks prevent spread of viruses

A new laboratory study supports the long-debated view that airborne viruses play a role in spreading influenza and that N95 respirators provide the best protection against airborne viruses, with surgical masks affording much less.

They found that flu viruses floated between the two and were “inhaled” by the breathing mannequin, but that an N95 respirator sealed to the mannequin’s face stopped 99.8% of them.

In another new study, Chinese hospital staffers who wore N95 respirators all the time enjoyed significantly lower rates of clinical respiratory illnesses (CRIs) than workers who wore surgical masks or used N95s only for high-risk procedures.

The researchers also found that workers who continuously wore the respirators had lower rates of bacterial colonization when they had respiratory symptoms, according to their report in the American Journal of Respiratory and Critical Care Medicine.

The primary way of person-to-person corona virus transmission is via aerosols or small droplets created by breathing, sneezing or coughing. The reach of exhaled air can be effectively reduced using a face mask as shown in the video.

N95 respirators are part of a class of respiratory protection devices known as mechanical filter respirator. These mechanically stop particles from reaching the wearer’s nose and mouth. Watch the video above to see how N95 Masks stop viruses.
