That's not correct. It depends on the water filter. A common Brita filter doesn't filter lead. But the referenced filter (Epic) does. There are other filters that can do that, the most popular is ZeroWater, which you can check their datasheet https://www.zerowater.eu/wp-content/uploads/ZeroWater-NSF-ce...

Be dubious of those claims. Lead can be in hundreds of chemical compounds. I very much doubt they have tested the filter against all of them.

Only reverse osmosis will do a decent job of removing lead, and even that won't be perfect.

The problem with ZeroWater is it filters out everything. I would be always thirsty after drinking from ZeroWater, it was a weird feeling.

So then you have to remineralize it...

But how are those minerals being sourced, and does that mixture contain lead? Ugh, it never ends.
