When it is finished all the impurities are removed. Now you can enjoy pure clean water at a low price.
Stage 1: A fine mesh filter removes heavy solids.
Stage 2: A sediment filter removes undissolved solids.
Stage 3: An activated carbon filter removes organic contaminates.
Stage 4: A micron carbon filter removes pesticides and herbicides.
Stage 5: Reverse Osmosis (RO) filtration removes inorganics, metals, and radionuclides.
Stage 6: Ultraviolet light removes bacteria, eliminates Chloroform, Giardia Lamblia, etc.
