High Compatibility: The countertop water filters are compatible with most gravity filtration systems on the market, including Berkey, Travel, Light, Royal, Imperial, Crown, and more, meeting everyday usage needs. Cost-Effective: Each pair of filters provides sustainable filtration for up to 6,000 gallons, with replaceable filters to meet ongoing needs. 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. 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. 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.
