What Copper and Zinc Really Do to Your Drinking Water (And What They Can't Do in a Blackout)

#copper #survivalskills #waterpurification A viral video says copper wire and a zinc strip, twisted together and dropped in dirty water, will purify any water overnight. No filter, no electricity, five dollars. I’m Finn, The DIY Guy, and I went through the patents, the NASA records, the EPA registrations and the university studies, one claim at a time. Some of it is real. Copper-zinc KDF media does remove chlorine, and copper pots killed six kinds of disease bacteria in a lab study. But EPA-funded researchers found these metals can’t be the only step in making water safe. NASA’s Apollo purifier used silver ions and electricity, not copper and zinc. And the EPA copper registration covers door handles, not drinking water. Then I rank what actually works when the power goes out or a boil-water notice hits: Stored water The 40 gallons already sitting in your water heater, and the one step you must take before you drain it Boiling The CDC and EPA bleach dose that treats about 7,000 gallons for $10 How to read NSF filter certifications There’s also a full shopping list with real prices. I’m not a doctor or a water scientist, and I didn’t lab-test any water. Everything here comes from public sources you can check yourself (listed below). Always follow your local health department’s instructions.
