Who had a homemade mask made
For those that want to know the filtering capabilities of the 2 Layer Cotton masks and the 2 Layer Polypropylene Fabric masks, here is a test for each as follows.
Both the Cotton Fabric and the 100% Polypropylene Fabric filtered quite well. The first Layers caught most of the white baking soda on the test using a Shop Vac with a black sock over the end to show if any backing soda pulled through the filter materials.
2 layer orange cotton test:
Single layer cotton opened up as 1 layer, after test:
2 Layer Gray Polypropylene Fabric test:
Gray Polypropylene opened up as 1 layer after test:
First layer does a great job of catching the debris. 2nd layer for added safety.
Sent a few of the Gray Polypropylene Masks off for our local Mail Carriers and Post Office employees here in town.
