epic water filter + nalgene 32 oz hdpe bottle is a great, lightweight filtered drinking water on-demand system filter pitchers are easy to use and a good safe guard against poor plumbing if you haven't had your home water tested

It is my understanding that the common filter pitchers don't filter out lead.

  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-certificaat.pdf https://www.zerowater.eu/wp-content/uploads/ZeroWater-NSF-ce...

    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.

    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.

HDPE Nalgene bottles probably leach PFAS: https://www.reddit.com/r/Nalgene/comments/wqdgbi/are_nalgenes_pfas_free/ https://www.reddit.com/r/Nalgene/comments/wqdgbi/are_nalgene... Glass or stainless steel would be a better choice (especially for storage).

  Whats my risk of exposure to lead from improperly made glass or stainless steel?
  - londons_explore 3y ago
    Stainless steel could easily contain quite some ppm of lead. Metals are frequently recycled, and hard to separate. Glass could also contain lead in contaminants - but actual metallic lead won't end up in the finished product - but lead oxides might well. Having said that... There are probably many devices in your house or supply chain which deliberately contain lead in double digit percentages. Worry about those before worrying about contamination.

Worry about those before worrying about contamination. I cycled pulverized lead paint around my alveoli as a kid doing construction and used to bite lead fishing weights when I was very young to make sure they stayed on the line. Thankfully it is now stored in my skeletal system for future use by my nervous system.

Micro plastics in the Nalgene, especially if it’s exposed to any sort of heat. There’s no BPA, but there have been “cousins” of BPA created that essentially are just as, if not more, harmful
