Premium Difference: We use only the highest quality, all-natural coconut shells. Finer particle activated carbon enhances the filtration process and results in a better taste. We use 30% more activated charcoal than other brands. Using our unique dual micromesh layer design allows us to use ultra-fine particle charcoal. Finer particle charcoal means more efficient, faster filtration compared to OEM filters. This combination delivers a filter with unparalleled filtration performance. Benefits: Removes chlorine (taste and odor), copper, mercury, zinc, fluoride and cadmium. Enjoy healthier, better-tasting water with less waste. Our unique dual micromesh layers keep all the charcoal in the filter and out of the coffee machine, extending the life of your machine. Brew the best-tasting beer every time with our premium water filters, which use double-layer protection and ultra-fine charcoal to remove impurities.
