https://berkeywaterfilter.us/r....oyal-berkey-water-fi Make Sure You Have Access to Clean Safe Drinking Water Anywhere You Are! Royal Berkeys are the #1 bestselling mid-size portable water filter in the U.S., a little bigger than the Big Berkey Water Filter. It Removes parasites, pathogens, chemicals and even fluoride. 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
