Why Boiling and Filtering Aren't Enough for SAFE Drinking Water

Boiling makes water microbiologically safe—but it doesn’t remove dissolved chemicals, fuel, heavy metals, or salt. Filters remove grit, protozoa, and most bacteria, yet most don’t stop viruses. Chemicals (like chlorine dioxide) can inactivate microbes but struggle in cold or cloudy water. So… what actually keeps you safe? In this field-tested guide, we break down Boil vs Filter vs Chemical, show you a simple decision tree by source, and reveal the fail points that make people sick—plus when and how to combine methods for a near fail-safe result. What you'll learn: What each method does / doesn’t remove A decision tree for streams, ponds, post-disaster tap, snow/ice, and silty rivers When to combine Filter → Chemical, Filter → Boil, or add UV/Carbon Hidden failures: freezing filters, ignoring contact time, treating turbid water, cross-contamination Smart gear setups for 72-hour kits, backpacking, and urban emergencies Chapters: Intro – “Boil ≠ Safe?” What each method really does Decision tree by water source When to combine (fail-safe stacks) Common mistakes & hidden failures Field checklist & closing If this helped, like, subscribe, and share with someone building a bug-out bag or 72-hour kit.
