Pentair four-stage reverse osmosis system

Payment and delivery details


If you are interested in purchasing this product, please get in touch.

Pentair Water’s inventive four-stage system delivers the purity of reverse osmosis water treatment in less space, driven only by average home water pressure.

No pumps or water storage tanks are needed. This means no pump noise and a smaller footprint than typical units, making placement easier under a kitchen sink.

While small in size, the Pentair Water RO System is big in filtering capability. The four-stage filtering system is able to reduce substances as small as 1/1000 the width of a human hair (a size which includes molecules of lead, arsenic, radium and many other toxins).


Each stage adds an extra level of clarity, cleanliness and taste

1) A carbon pre-filter traps large particles, maintaining a strong water flow

2) Dual Stage reverse osmosis elements work in tandem to further reduce impurities* and increase efficiencies

3) An additional carbon post-filter maximizes the water’s freshness and flavour

* For specific reduction levels please refer to the performance data sheet
