I’ve read that Brita elite filters do capture some PFAs. However, it is well known that Brita filters and the like aren’t as efficient and effective as more dedicated solutions.

That is to say, no, they’re not bullshit – they’re better than nothing, but they’re just a marginal improvement. From my limited research so far I think it’s correct to say that you’re paying Brita more for a convenient system than for efficient and high quality filtration.

Only let the OP add new title candidates, but then use reddit voting to select the replacement?

Probably still game-able, though
