5-stage of filtration:

1. PP fiber removes the rough impurity in water such as rust, sand, microbe, etc.

2. Special grain carbon, high absorption function, can fully absorb organic materials. If can also remove odors, bleaching agent chorine, pesticide, and carcinogen.

3. More precise (micro powder active carbon) absorb isolated material.

4. Super strong RO (0.0001micron) membrane, exactly filters those impure materials by RO principle, totally isolate impurity from pure water.

5. Super active carbon removes remained micro organism and foul smell.
