Five-Stage Filtration

Water is filtered in five stages, and each stage has a specific role to play in the filtration.

Stage 1: Large particles such as dirt, silt, rust, and sand are filtered by the Polypropylene Sediment, which is melt-blown and is 5-micron in size.

Stage 2: Granular Activated Carbon (GAC) filters to remove organic compounds such as chlorine that add intolerable taste and odor to the water.

Stage 3: A second carbon block which is 5-micron in size made of fine coconut shell to remove Volatile organic compounds (VOC’s) and other harmful chemicals. It also removes any remaining chlorine odor and tastes.

Stage 4: It is a Thin Film Composite (TFC) membrane and an essential unit of the Reverse Osmosis. It filters bacteria and chemicals and helps to achieve 99% purity.

Stage 5: The final stage removes any remaining bad taste or odor. It consists of Inline Granular Carbon Polishing Filters.
