Reverse Osmosis Systems
Clean, great-tasting drinking water straight from a dedicated tap.
What Is Reverse Osmosis?
Reverse osmosis pushes water through a semi-permeable membrane that blocks dissolved solids too large to pass through — including sodium, nitrates, fluoride and many other contaminants. It is the most thorough filtration available for a single drinking-water tap, producing clean, great-tasting water for drinking, cooking, coffee and tea.
How an RO Drinking Water System Works
A typical under-sink system works in stages: a pre-filter removes sediment and chlorine to protect the membrane, a high-efficiency Pentair GRO-75EN membrane does the heavy lifting on dissolved solids, and a post-filter polishes taste before water reaches a dedicated faucet. Systems include a storage tank so pure water is ready on demand. We can install yours within 5 business days.
Pentair GRO-75EN Membrane: Key Specifications & Features
- Water efficiency: operates at an impressive ~1:1 waste-to-purified water recovery ratio — saving up to 50%–75% more water than conventional 3:1 or 4:1 systems.
- Flow rate: produces up to 75 gallons per day (284 litres per day).
- Rejection rate: approximately 96% nominal contaminant rejection performance using Thin Layer Composite (TLC) technology.
- Design: encapsulated “dry packed” cartridge with 1/4” quick-connect fittings for fast, clean installation.
- Certifications: NSF International tested and certified.
