World Leading Technology

How our purification process works

Granular Activated Carbon (GAC)

Stage One

Granular Activated Carbon (GAC)

The Carb12 pre-filter removes chlorine and other organic impurities and serves to protect Stage Two, the Reverse Osmosis membrane, from damage. GAC is an excellent media for the absorption of chemicals found in raw tap water but has little or no affect on dissolved solids, micro-organisms, heavy metals, pathogens and viruses. Jug filters and filter taps use small quantities of GAC as the primary process to improve the taste of tap water. GAC is an effective filtration media rather than a purification process.

Reverse Osmosis (RO)

Stage Two

Reverse Osmosis (RO)

With the chlorine removed, the raw tap water passes into the Reverse Osmosis module. Our own patented thin film composite (TFC) membrane is the only RO with US Environmental Protection Agency (EPA) certification meaning this is the only RO system certified suitable for the removal of micro-organisms from water. At 0.0001 microns it’s capable of removing 100% of disease causing microorganisms and up to 98% of inorganics and 70% of nitrates. Our patented flushing mechanism removes scale and biofilm extending membrane life to up to ten years.

De-Ionisation (DI)

Stage Three

De-Ionisation (DI)

Another unique and essential feature of our patented system is the deionisation module. The impurities that breach RO can only be removed by DI. This stage is an ion exchange process removing heavy metals, nitrates1, gases, volatile organic chemicals2 and oestrogens, replacing them with hydroxide (OH) or hydrogen (H), better known to us as H2O. The result is Pure H2O, the purest water available.

1 Nitrates have a habit of mimicking oestrogen and starving the red blood cells of oxygen. They should be removed from drinking water.

2 Nitrates and volatile organic chemicals hide the hydrogen bond of the water molecule that makes them invisible, thus, passing through RO but not DI stages.

Granular Activated Carbon (GAC)

Stage Four

Granular Activated Carbon (GAC)

The final stage, a post-filter ‘polishing’ process, ensures any residual gases are removed producing a great taste.

Why choose a PureH2O Purity Professional tap water purifier

Why choose a PureH2O Purity Professional tap water purifier

All PureH2O Purity Professional tap water purifiers feature…


Connect to our Quatreau™ tap collection, coffee machines, steam ovens, ice makers and glass washers.


Unique mechanisms separate purified water from feed water, ensuring consistent water purity.


Purity Professional purifiers feature fully automatic, system-activated self-clean for total convenience.


Our professional water purifiers are the most water-efficient reverse osmosis systems on the market, with intelligent management systems to minimise resource use and financial costs.

Lower service costs

Because our patented self-cleaning flush process removes plaque, the membrane in a Purity water purifier lasts I0 times longer than those in other RO purifiers on the market, saving £I00 a year (£I,000 over a I0 year period)


Most commercial premises will usually have everything our engineers need to install your PureH2O Purity Professional water purifier; a 15 mm isolated mains cold water supply, a 13 amp powerpoint and a trapped drain with upstand (if not, we can make a connection to a trapped drain on a sink).

Servicing & Warranty

We offer a 3 year warranty on Purity Professional water purifiers subject to Annual Service by a PureH2O expert engineer.

Purity Pro 500 - 2,000

Purity Pro 500 - 2,000

The Purity Pro 500 – 2,000 water purifier delivers ultra high volumes of pure drinking water of exceptional quality, serving up to 2,000 people. It replaces single-use plastic or glass bottled water to minimise environmental impact, reduce financial costs and maximise convenience.


Our advanced ultrafiltration (UF) pre-treatment followed by reverse osmosis (RO) purification process protects against deliberate radiological, chemical and biological contamination and removes the myriad of contaminants and impurities found in feed water including disease-causing microorganisms, heavy metals, fertilisers, pesticides, hormones and medications.

Feed Sources

The HRS reverse osmosis purification system can process multiple and mixed water feeds (which do not need to be potable), including rain, mains and bore water.

Production Rate

We have tank options which supply 500, 1,000 or 2,000 litres of pure drinking water per hour, all of which have high recovery rates with continuous 24 hour production.

Recommended for

Large buildings serving up to 500, 1,000 or 2,000 people (depending on chosen tank size).


The Purity Pro 500 – 2,000 is typically installed in a plant room, we can advise on installation at your site.
