Are Brita filters bullshit? (lemmy.ml)

I have one of those pitchers that I mainly use to get rid of the chlorine taste in the tap water, but are the actual health claims about drinking filtered water actually true? There are claims that these dinky little passive filters can get rid of things like lead and PFAS which I honestly don't believe. Especially if you're using it with tap water which I'd assume would always have some kind of active filtration before it gets to your home, so the idea that whatever got past the industrial grade filter at the water treatment plant can be caught by a little plastic one sounds more than a little fishy to me. Anyone have knowledge about this.

I just use those filters to get rid of the hardness in the water due to drinking tea.

Britta filters can reduce water hardness to a little margin but I wouldn't bet on those to reduce water hardness...

Better have specific filters under the sink to reduce those carbonates or if you have some money to spare (~1000$) a specific machine directly connected to your water income in the basement !

The ones we use, lasts for about 2-3 months.
Usage is 1L every two days with moderate hard water.
You definitely see the reduction from the tea I have at home vs work.
If I leave the tea at home to cool on the desk, it still hasnt developed the thin film of (I believe) tannins in comparison to the tea at work which looks like I could walk on it.
