Description
The 100 GPD 5-Stage RO Purifier with Smart Faucet is a reliable tank-based reverse osmosis system for family kitchens. It uses standard 10-inch cartridges, a 100 GPD membrane and a pressure storage tank, paired with a smart faucet that displays water quality and filter status. It brings modern convenience to a proven, easy-to-service design.

Why choose a tank-based system?
Tank systems are simple, need no electricity when mains pressure is good, and use widely available cartridges, so running costs are low. The 100 GPD 5-Stage RO Purifier is a strong value choice for most homes in Muscat. For faster flow without a tank, compare our tankless models in the reverse osmosis systems range.
