Glass bottles and a Berkey! https://image.nostr.build/d3b785eba1c54a338cc5e88eff554727df15e26f65ad64d742e46f2212ff3753.jpg#m=image%2Fjpeg&dim=279x474&blurhash=%5DnONB%40of%7Eq%25Mof%25LD%25xu%25MM%7Bt7xuM%7BRit7Rjofofayfk%25MRjWBofWBWBozWBWBoft7ofWBWBayfRWBofofayxuofRjWBfQ&x=e538b01af5387434d02d29341a645947ac7df7b5262064ba7f7c465f48113246
Check out Burkey water filters - top notch - last 5 years - leaves in the healthy minerals (vs reverse osmosis that removes the good stuff). Popular with prepers too. nostr:nevent1qqspv89yr9hjvac6k7dwvcsky50h9gxqmazqy76mhhwpqljeu04dy6qpz3mhxue69uhhyetvv9ujuerpd46hxtnfdupzq50uwgyjqxc5znmjrs7j62e5xp5ek8nrzackc5vzeswhj3g89c6cqvzqqqqqqyqyt93q
My RO filter has an insert that adds them back in. Inefficient, but it filters much better than these. (I've tried both)
However, I live in a place that has super hard water and the Berkey didn't like that at all. In fairness, I believe the product info warned of that. So it may actually work well for some people.
love my berkey
