It's utterly bizarre. I bought a cycle pollution mask at the start of the scamdemic, it arrived and had valves on it for the air to escape. I thought, "that's a bit shit, then I realized that the surgical masks had bigger gaps at the side. There was never any sort of mandate on the type of mask you had to wear, only that you had to wear one. It was all psychological to keep up the illusion of a pandemic.
