Why? PFAS is pretty large, and is readily removed by activated carbon, particularly GAC (Granular Activated Carbon), Ion Exchange Resin, and Reverse Osmosis. Multistage RO filters are "Dead simple to install and replace". Do you have any reason, or is doubting just a way of life for you? FWIW, I have RO filtration for my drinking and cooking water. You might want to consider it.
I doubt your house filter removes PFAS either.
