The Inline 4-Stage Reverse Osmosis Kit includes:

• 1 x 1st stage: 5-micron Sediment Filter Removes particulate matter before reaching additional filters. Does not remove chemicals or heavy metals.
• 1 x 2nd stage: Pre-Carbon (GAC) Removes sediment and compounds that reduce second or third-stage filter life.
• 1 x 3rd stage: Reverse Osmosis Filtration. Reverse osmosis pushes water through a semi-permeable membrane at extremely high pressure. The result is crystal clear water that is free from virtually all impurities found in municipal water sources.
• 1 x 4th stage: ACB (Activated Carbon Block) Filtration, using NSF certified Carbon Materials pressed to a block rated at 0.5 microns, an ACB filter is effective at improving clarity and taste of water without removing its natural healthy minerals and nutrients.
