I don't know. We have started using Epic Pure filters. They claim to filter PFOA/PFOS [1].

Don't take this as a recommendation though. I have no expertise in this at all and I haven't done any tests to confirm whether Epic's claims are actually true.

Brita filters also have ion exchange resin as well as activated charcoal. However it's not enough to remove PFAS, there was a lawsuit about this, if you do a search.

my understanding is not as much and not as consistently as more advanced filters

No.
