What’s Your Go-To Low-Tech Water Purification Method?
Always curious what people rely on when the filters run out or supplies are scarce. I’ve used the old standby of boiling, but I keep coming back to gravity-fed ceramic filters for regular use since they’re reusable and not too delicate. Has anyone found a particularly reliable DIY method that doesn’t rely on commercial elements? Would love to hear about any natural filtration techniques using things like charcoal from a fire or sand if you've tried them in the field.
