This is when the argument can be reduced to absurdity, e.g. banning the Bible for the sexual imagery in it. Ban absolutely anything and everything even remotely objectionable to anyone (there are people with feet fetishes, ban all feet, and thus also all shoes), so there’s no Internet at all.
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.
If you worked a shitty job that only earned $1 a day after accounting for work-related expenses (e.g. transportation, professional equipment, taxes, etc), it would be profitable, but not worth your time.
And there are inflection points where it’s going it be easier to cut out the middlemen.
Either 1:0 or 0:1, depending on my mood
