@Infoseepage i didn't consider rain on the pancake filters, because I live on a semi arid island that has months where it doesn't' rain, and can usually avoid going out on the days it does rain. I had a mutual on another social media platform from Seattle, who was also concerned about rain resistant filter housings, so that makes sense.
By the way, you might find it useful to know that, unlike NIOSH certified filters (which are bright pink) the European CE rated versins of filters are white (FFP3 is closer to n99 than p100 if that matters, though)
@Infoseepage That's pretty much what the white stealthmask is/was. They took their black industrial mask and changed he color to white, and yeah, the pink filters are a legal requirement in the US, which is why I mentioned the EU versions being white. I actually had an EU GVS for a while ( I used it up), and the white ffp3 fitler is a lot less in your face than the pink p100 (also MUCH easier to breathe in)
