The list is so long you can’t fathom how much it impacts. Pretty much anything with anti- or resistant used to describe it has some sort of PFAS compound. We can live without PFAS, but we would need to do like people used to do and give up a lot of creature comforts.

One thing it’s commonly associated with is surfactants, so no fancy shampoo, but also probably no washing machine because it doesn’t scour your clothes well enough. Plumbing uses it to join pipes. Any sort of metal finishing/coating uses so no more chrome or nickel plating unless you want it to look like you dug it up at a 500 AD site. One of the higher containing things I’ve seen was women’s make up.
