COVID-19 Cloth Masks

We are currently suggesting using only cotton cloth or non-woven polypropylene (unused or laundered reusable shopping bags) for use in DIY masks.

Other materials are not currently recommended for DIY masks and may be hazardous to your health!

Both cotton and non-woven polypropylene masks may be boiled for 10 minutes for sterilization.

Cotton masks may be washed in a standard washing machine with soap.

Using Cotton Fabric

                Take the following design but add a third layer of non-woven into the design cut to the same size of the male main pattern. You don't need to add a wire unless you want to.

The United States Centers for Disease Control and Prevention provides information on constructing cloth masks from COTTON.  Three designs are shown:  sewn, t-shirt no-sew, and bandana.

Using Non-woven Polypropylene Reusable Shopping Bag

Maker Mask - Mask Cover and Surge Mask designs can also be made from NWPP based their designs and material choices on research and testing.  Their website contains links back to the sources, and provides rationale for the material they chose, as well as reasons why other materials should not be used.

A hard surface that is somewhat of an insulator is probably best.
