What’s Your Go-To Low-Tech Water Purification Method?

[BlueHarborTea]

Boiling is always my first choice when it comes to purifying water, but I’m curious what other low-tech methods folks actually rely on when boiling isn’t an option.

I’ve practiced using coffee filters to remove debris before treating with bleach drops, but I’d love to know what tried-and-true methods work best for you, especially in off-grid situations. Any field-tested

I’ve put a lot of faith in bio-sand filters over the years, especially for longer-term situations. Those take a bit of time to build and “mature,” but they do a good job filtering out bacteria and particulates if you keep them running properly. Solar stills can work in a
