There are probably no products for individual consumers that contain large amounts of PFAS and that are indispensable.
Small amounts of hard to replace PFAS may be contained in devices such as antenna connectors for devices with WiFi (which cannot cause pollution unless destroyed in an inappropriate way).
Nevertheless PFAS are absolutely irreplaceable in various chemical equipment used in chemical analyses and in various fabrication processes, for instance in the fabrication of all semiconductor devices (because no other substances have comparable corrosion resistance). PFAS would also be very difficult to replace in a few other applications, e.g. vacuum seals and insulators for high-frequency applications (as no other materials have a similar combination of low dielectric constant and low losses).
In all such industrial applications the risks of pollution are much smaller than in mass-market applications. However, it is likely that after PFAS will hopefully no longer be used for mass-market applications their price for professional applications might increase a lot, causing some price increases in other products, e.g. electronic devices.
