Under Sink Reverse Osmosis (R.O.)

Advanced Purification Right at Your Kitchen Tap

An Undersink Reverse Osmosis (RO) System delivers ultra-pure, great-tasting water directly from a dedicated faucet at your kitchen sink. Designed for convenience and performance, this compact system removes a wide range of contaminants, making it ideal for drinking, cooking, and baby formula preparation.

Microline R.O.

The name may sound technical, but osmosis is a natural organic phenomenon that occurs in nature on an everyday basis. RO systems force water under pressure through a semi-permeable membrane and a series of pre-filters then into a storage tank that holds the treated water until it’s needed. A dedicated external faucet is included so that the stored water is only used when desired.

RO system filter modules include:

• A pre-filter that captures larger particles, chlorine and other substances.
• A semi-permeable membrane filter that captures finer contaminates
• An activated carbon filter that takes care of residual taste, odor and additional organic contaminates.
• RO systems reduce bacteria, cysts, sediment, chemicals, lead & other heavy metals, dissolved solids, chlorine taste and odors.
• Maintenance includes periodic replacement of the pre-filter, semi-permeable membrane and activated carbon filter cartridges.

How It Works

Municipal or well water flows through a multi-stage filtration process:

• Sediment Filter – Removes dirt, rust, and particles that could clog the system.
• Carbon Filters – Reduce chlorine, chloramines, and chemical contaminants that affect taste and odor.
• RO Membrane – Filters out up to 99% of contaminants including lead, arsenic, fluoride, nitrates, and more.
• Polishing Post-Filter – Enhances taste and clarity before water is dispensed.
• Purified water is stored in a pressurized tank and delivered through a dedicated faucet installed at your sink.

An undersink RO system removes up to 99% of contaminants, including lead, arsenic, fluoride, nitrates, chlorine, PFAS, bacteria, and more. It provides safe, clean drinking water ideal for cooking, baby formula, and everyday hydration.

Most systems are compact and fit easily in standard kitchen cabinets. A typical setup includes a filter assembly and a storage tank, requiring approximately 2–3 square feet of space. Slimline models are available for tighter installations.

Sediment & Carbon Filters: Every 6–12 months

RO Membrane: Every 2–3 years

Post/Polishing Filter: Every 12 months Regular maintenance ensures optimal water quality and system performance.

Yes, reverse osmosis systems create some wastewater during the filtration process. However, modern systems are more efficient, and options like permeate pumps can help reduce waste and increase water recovery.

RO systems use a pressurized storage tank to deliver consistent water flow. While not as strong as your regular faucet, it’s more than sufficient for drinking, cooking, and filling pitchers or bottles.
