L.A. and other water districts are now going to start use recycled raw sewage (think diarrhea) as tap water! Don't be without a way to make purified water out of any water. When electricity goes out, a lot of filters stop working and so do water districts (or water rationing and shortages.) Make Sure You Have Access to Clean Safe Drinking Water Anywhere You Are! Big Berkeys are the #1 bestselling portable water filter in the U.S. Removes all parasites, pathogens, chemicals and even fluoride to give you ultra pure clean drinking water from tap, river, lake, stream or pond water. Should be in every prepper's emergency kit. I am so glad to have mine (with fluoride filters) as I would never want to depend on our Gov for clean water! berkey #waterfilter #waterpurifier #royalberkey
