What Is an Under Sink RO System

An under sink RO system, such as the one available at under sink RO system, is a reverse osmosis water purifier that sits inside the sink cabinet. The term “under sink” simply means the unit is installed in the storage area below your kitchen sink but still offers easy access for filter replacement and maintenance.

This system purifies water by pushing it through multiple stages of filtration: sediment, carbon, RO membrane, post-carbon, and optional mineral enhancement. The result is clean, healthy water with reduced TDS and improved taste.

How an Under Sink RO System Works

Stage One: Sediment Filtration

The first filter removes visible and invisible solid particles like dust, mud, rust flakes, and sand. This protects the RO membrane from damage.

Stage Two: Activated Carbon Pre-Filter

The carbon filter removes chlorine, chemicals, volatile organic compounds, and odors, ensuring water tastes and smells clean.

Stage Three: RO Membrane Purification

The RO membrane is the heart of the purification process. It pushes water through a fine membrane that blocks dissolved solids, heavy metals, bacteria, viruses, fluoride, nitrates, and other harmful contaminants.

Stage Four: Storage Tank

Purified water is stored inside a pressurized storage tank installed under the sink. This ensures instant water availability at all times.

Stage Five: Post-Carbon Polishing Filter

Before reaching the faucet, water passes through a polishing filter that enhances taste and ensures purity.

Stage Six: Dedicated Purified Water Faucet

The system comes with a separate faucet installed on the sink counter. This faucet delivers only purified water, preventing cross-mixing with tap water.
