A note about Mistyfuse and Masks, in the time of COVID19
The answer is yes it is.
Mistyfuse is inert, has resistance to moisture, and most importantly Mistyfuse is made without industrial additives commonly found in fusibles, such as solvents, blow additives, and body modifiers. And there are NO surface adhesives added. Mistyfuse does not off-gas when ironed. The structure of Mistyfuse's engineered true-web allows it to handle like a fabric and be breathable. Instead of holes from stitching, this web melts into and becomes entwined with the fibers of fused fabrics—also impeding the passage of viral particles.
Please wear a mask. Stay safe. Protect others.
