FFP3 fabric

[Lemne]

I am looking for some FFP3 fabric to make some filters from for my own masks. I know people were using duct filters and breaking them down but you can't get hold of those for a reasonable price at the mo. I don't trust anything from China either as so many fake products. Does anybody have any ideas or sources?

Don't some vacuum cleaner bags have suitable filtration properties. Or coffee filters at a push?
