The practice of adding fluoride to city drinking water has recently become a hot health topic. Not surprisingly, we’ve seen a steady increase in the number of inquiries about how to filter fluoride from drinking water. Aquatell offers the Aries line of fluoride filter cartridges. These are an activated alumina product that is highly effective in reducing fluoride concentrations in drinking water. These cartridges are often used in combination with sediment filtration and/or carbon filtration for a comprehensive drinking water purification strategy.
