To test the ,surgical masks,, we ,used, the same wind tunnel setup that was ,used, for our homemade ,mask, materials tests. In that setup, a fan on one side of a wind tunnel pushes air through the ,mask, on the other end. There, a Met One GT-521 laser particle counter measures how many particles penetrate the ,mask,.
An N95 ,surgical mask, is an enhanced reusable face ,mask, that combines N95 respirator and an ordinary ,surgical mask,. Most of the fashion ,masks, made from washable cotton or sponge are reusable, they are mainly designed for air pollution or pollen allergy, but useless against viruses and bacteria.
The history of the ,surgical mask, can be divided into three separate eras, the first being the development and testing of the ,mask, from 1905 to 1920, and the second being the period when the importance of the ,surgical mask, was stressed and new ,masks, were developed, 1920-1940.

Background: ,Surgical masks, have been ,used, since the early 1900s to minimize infection of ,surgical, wounds from wearer-generated bacteria. There is ongoing debate, however, whether ,surgical masks, can meet the expectations of respiratory protection devices. The goal of this study was to evaluate the filter performance and facial fit of a sample of ,surgical masks,.
The melt-blown material acts as the filter that stops microbes from entering or exiting the ,mask,. Most ,surgical masks, feature pleats or folds. Commonly, 3 pleats are ,used, allowing the user to expand the ,mask, so it covers the area from the nose to the chin. There are 3 different ways to secure the ,masks,.
