Reverse osmosis is pretty much the gold standard for removing PFAS. You can get countertop units for a reasonable price. Look for the lab testing or certifications rather than random anecdotes since they appear to work fine to the end user.

As someone new to this how do the details work? Do you need to buy a new membrane often like I imagine? Do you have any issues with your water lacking minerals? (in the same way drinking distilled water is bad for you)

The model I have says to replace the filter once a year, and it's $170 AUD. I imagine you could probably get away with using it longer than the OEM recommendation though.

I had the same thought about demineralised water, you can get more expensive models which remineralise the water after, but it looks like it's not actually that important health wise because you get the absolute vast majority of your minerals through food, not water. And remineralisation is mostly for taste rather than health. Though I don't find the demineralised water tastes bad, but if you're used to drinking hard water it might be different.
