This video demonstrates some testing that we performed on the 3M 6800 Full Face Mask. We are using 3M 2091 P100 filters. The mask is tested using a custom setup. We took a mannequin head and drilled three holes and placed plastic tubes through the head to measure air from different areas. One tube goes to the forehead. One holes goes to the mouth. One hole goes to the nose. The forehead and nose holes are used to sample air in different compartments. In this video we using the forehead and nose tubes. The air from the mask goes to a four part manifold which allows the air to be measured by the PCE particle counter. The mouth hole is connected to a tube which will allow us to eventually simulate breathing. We are still working on this part of the set up. The four sections manifold allows sampling of the ambient air and also to flush the manifold with filtered air using a ventilator filter for filtration. The PCE particle counter measures particles as small as 0.3 microns. A micron is 1/1000 of a millimeter.
The one downside to this mask is that exhalation port is not filtered. If you are an asymptomatic carrier of COVID-19 you can spread the virus with this mask. There is also no voice diaphragm which makes talking somewhat difficult. The mask itself is quite comfortable and the seal is made of nice soft rubber like material.
Based on the measurements we made, this mask should work against COVID-19. Nonetheless, this mask was not designed for biologic particles and caution should be used when using this device for this purpose.
