- graemep 2mo agoDefinitely. I think considerably more. I have seen the ceramic ones that seem to be a design that goes back to Victorian ones. https://en.wikipedia.org/wiki/Ceramic_water_filter https://en.wikipedia.org/wiki/Ceramic_water_filter In the Sri Lankan context filters are more important than ever, but I think activated carbon ones? Water is (heavily, I think!) chlorinated but pollution is pretty bad.
