Best Ways to Purify Water Without Electricity?
Looking for reliable ways to purify water off-grid, without any electricity. I know about boiling, but that requires fuel, and I'm interested in sustainable back-up methods in case fuel runs low or isn’t available. Tried basic gravity-fed filters (like Berkey or homemade units) and chemical treatments (bleach, iodine), but not sure which is safest for long-term, especially for larger groups.
Does anyone have hands-on experience with solar disinfection (SODIS) or ceramic filters? Also wondering if slow sand filtration is practical for DIY setups when you need several gallons a day. How effective are natural coagulants like moringa seeds for clarifying really murky water before filtering? Any tips on maintenance or common mistakes to avoid with these systems?
Would appreciate advice on what works best in prolonged grid-down situations—especially methods that can be managed by folks who might not be super handy. Redundancy is key, so any suggestions for layering purification methods would be great. Please share real-life results if you’ve relied on any of these in an actual emergency, not just theory.
