With a few production tweaks, Melitta—a company known for coffee filters—is now churning out millions of essentially medical-grade, coffee filter-shaped face masks.
—will tell you, they already make a standard-sized cone filter that fits the face perfectly. Instead, the problem is the material: Paper isn’t great for keeping out coronavirus, but the fibers Melitta uses for making vacuum filters is.
Ironically enough, one of the trickier steps appears to be getting government approval to sell the masks as a medical supply—Melitta is still waiting on that—but thewrites that the material, “a triple layer of melt-blown and spun-blown microfiber,” has a Bacterial Filtration Efficiency certification that’s similar to basic medical masks already in use.
As a result, in theory, medical professionals could use a mask to protect themselves and a filter for the coffee that helps get them through their shift that were made on literally the same machine. But don’t get the two mixed up: Just like a coffee filter doesn’t make for a perfect mask, the masks apparently don’t make a very good cup of joe.
Melitta coffee filters are available in America, but for now, at least, the masks are not being sold outside of Germany.
