I bought masks from a toy company (Playmobil) for my family, because there was literally nothing else available anywhere. They were marketed as alternatives to basic paper masks though, not N95 masks:
The innovation was that you could use tissue paper as filters and reuse the silicone mask after cleaning it. They were uncomfortable and stinky, but functional. We used these for about a month or two, long before any vaccines were available. I suspect that social distancing protected us far more than the masks, but either way, none of us got infected.
