    Ceramic filters are very common in Brazil, used in clay recipients which also keep the water cool even in summer without spending energy.

    There is a company[1] in Indonesia that actually makes very nice versions of this tech.

      That ad claims it removes microplastics. I was led to believe there are few easy ways to accomplish such a thing. Is this a, "Well technically, we started at 100ug/mL and ended at 99.8ug/mL => reduction!" or is this a meaningful improvement in water quality? The pot looks to just be clay + charcoal + silver - which is not meaningfully different from other home water filtration systems.

      From https://www.terrawaterindonesia.com/the-filter:

      > A single Terra filter purifies up to 42 liters of safe, pure drinking water a day, equivalent of 2 and a half plastic gallons.

      Someone should tell them to check their math.

      I may have had an early version of this at home in Indonesia as a kid. Given how close we were to both sea level and the equator, the fact that the water was cool, even when site power failed for days, was bliss!

    When I was a kid, we'd go camping, and we had these water filters that you would pump water through, and they would filter it.

    It was ceramic, and I think it was the same idea, but we used a pump to force the water through (like a bicycle pump).
