Berkey Filters started serving water filter customers in the late 1990's. We started as a small family-operated business in a farming community just east of Pueblo, Colorado. We have always had one simple goal, "Always ensure every customer is 100% satisfied". Over the past 20+ years in business, we have helped millions of families take control of their water quality, with a Berkey Filter. The Berkey Water Filter System is unlike other water filters on the market, it is independently tested to remove 200+ water contaminants and is classified as a Water Purifier, the most powerful water filter classification.
