Premium Coconut Activated Carbon: The water filter uses food-grade coconut activated carbon. The carbon granules are uniform, effectively reducing odors and improving taste as water passes through. 99.9% Effective Chlorine Removal: The gravity water filter provides effective filtration with fine pores that remove 99% of chlorine from water. It improves water taste and reduces heavy metals, sediments, rust, soil, and other impurities. Three-Stage Filtration Design: The combination of activated carbon and ultrafiltration membrane provides triple filtration: the activated carbon layer reduces residual chlorine; the silver ion filter layer eliminates bacteria; the hollow fiber ultrafiltration membrane reduces heavy metals and other impurities. Cost-Effective: Each pair of filters provides sustainable filtration for up to 6, 000 gallons, with replaceable filters to meet ongoing needs. High Compatibility: The countertop water filters are compatible with most gravity filtration systems on the market, including for Berkey, for Travel, for Light, for Royal, for Imperial, for Crown, and more, meeting everyday usage needs.
