From a Guardian article:

Caroline Criado-Perez, whose book "Invisible Women" addresses the issue of ill-fitting PPE for women in one of its chapters, said she has been inundated with messages from healthcare workers who could not find protective equipment to fit them.
“Respiratory protective equipment is designed for a male face, and if it doesn’t fit it won’t protect,” she said. “Because of a dearth of sex disaggregated data we don’t know how many women are affected, but I am hearing on a daily basis from women in the NHS who say they can’t get their masks to fit.”

As I have said before, getting PPE is not the only criteria. It needs to be PPE of the right size and much of it is not suitable for women.
