1. Main Stage: UF (middle-hollow UF membrane; filtration precision: 0. 01Micron).
Functions: filtering germ, virus, corpuscle, other solute and chemical from tap water processing.
2. Assistant stage 1: in-line post active carbon filtration.
Functions: removing bad smell in water, mainly dissociative chloride.
3. Assistant stage 2: in-line post active carbon filtration.
Functions: adjusting filtered water taste, keeping water fresh.
4. Assistant stage 3: UF.
Functions: removing germ from the process of active carbon filltration.
4-stage filtration: 1. Filtered water output volume: 200 L/H. 2. Crossing filtration, very easy to clean it. No power or pressure-added needed.
