A pottery friend linked this review of a different type of filtration mask:

and I was wondering if anyone had tried it or researched it for using with enamels, etc. I don't have a background that gives me insight into all of the information and how it would apply to glass.
I've only used enamels a few times, and used an N95 paper mask from HD so far. I've also made frit a few times using the pound it inside a metal tube with a home made cruncher method, and that is another time I should probably be using a mask.
