It helps but doesn't stop it. Probably works in a warm atmosphere or the conditioned air of an operating theatre but never for me in whatever conditions obtain in the average supermarket. If surgeons had to do operations in Sainsburys there would be some right carve-ups.
I bought some FFP2 masks that are shaped and much better.
