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.

There's a lot of pipeline between the filter at the plant and your home which is where something like lead contamination would happen. However from wiki,

When filtering water, charcoal carbon filters are most effective at removing chlorine, particles such as sediment, volatile organic compounds (VOCs), taste and odor. They are not effective at removing minerals, salts, and dissolved inorganic substances.

And The EPA, make it sound like Carbon filtering is not an effective solution to PFAS contamination at an industrial scale. So I doubt your Brita pitcher is going to do better.
