Enjoy purified, great-tasting drinking water at home with the Ecosoft PURE Balance Reverse Osmosis System. Designed for installation beneath the kitchen sink, this advanced domestic water filtration system combines six stages of treatment with specialist mineralisation technology to produce purified water enriched with calcium and magnesium.

The PURE Balance uses a 75 GPD reverse osmosis membrane, capable of producing up to approximately 280 litres of purified water per day under rated conditions. Its AquaGreen technology is designed to improve water efficiency, with a manufacturer-stated recovery rate of up to 50%.

Unlike a conventional reverse osmosis system that produces very low-mineral water, the PURE Balance includes a dedicated Balance mineralisation cartridge. This adds calcium and magnesium back into the purified water, helping to create a more balanced mineral profile and improve drinking-water taste.

With a dedicated drinking-water tap and an integrated storage tank, the Ecosoft PURE Balance provides a convenient domestic drinking-water solution.

Six-stage reverse osmosis filtration

The Ecosoft PURE Balance combines sediment filtration, activated carbon, membrane purification and mineralisation in a six-stage treatment process.

Stage 1 – Sediment Filtration

The dual-gradient-density sediment cartridge captures suspended particles such as sand, rust, silt and other physical impurities.

This initial filtration stage helps protect the subsequent cartridges and reverse osmosis membrane from particulate contamination.

Stage 2 – Activated Carbon Filtration

The granular activated carbon cartridge uses coconut shell carbon to reduce chlorine and certain organic compounds that can affect water taste and odour.

Removing chlorine before the membrane stage also helps protect the reverse osmosis membrane from chlorine-related degradation.

Stage 3 – AquaGreen Water-Efficiency Technology

The AquaGreen cartridge is designed to help control scale-forming substances and improve the efficiency of the reverse osmosis process.

This technology supports the system's stated water recovery rate of up to 50%, helping reduce the proportion of incoming water discharged as concentrate compared with less efficient configurations.

Stage 4 – Reverse Osmosis Membrane

The 75 GPD reverse osmosis membrane is the main purification stage.

It separates incoming water into two streams:

• Purified water, known as permeate, which passes through the membrane.

• Concentrated reject water, which carries away a proportion of the dissolved substances retained by the membrane.

Reverse osmosis is effective at reducing many dissolved salts and other contaminants. Actual removal performance depends on the substance being measured, incoming water quality, temperature, pressure and membrane condition.

Stage 5 – Balance Mineralisation

After reverse osmosis, water passes through the dedicated Balance mineralisation cartridge.

This stage adds calcium and magnesium to the purified water, helping restore part of its mineral content and improve its taste.

Under the manufacturer's stated test conditions, the expected mineralised water profile is:

• Total mineral content: 60–80 mg/L

• Calcium: 10–15 mg/L

• Magnesium: 4–6 mg/L

• pH: 7–8.5

These are indicative manufacturer values, not guaranteed results for every installation. Actual mineral content varies with incoming water temperature, water composition and usage.

Stage 6 – Carbon Post-Filtration

The final coconut shell activated carbon post-filter provides a final taste and odour polishing stage before the water reaches the dedicated drinking-water tap.

AquaGreen technology – improved water recovery

One of the key features of the Ecosoft PURE Balance is its AquaGreen technology.

Traditional reverse osmosis systems discharge a proportion of the incoming water to drain as part of the membrane separation process. AquaGreen technology is designed to improve water efficiency, with a stated recovery rate of up to 50%.

A 50% recovery rate means that, under the relevant operating conditions, approximately half of the incoming water can be recovered as treated water, with the remainder discharged as concentrate.

Actual recovery depends on feed-water composition, pressure, temperature and system operating conditions.

Mineralised drinking water with calcium and magnesium

A key difference between the PURE Balance and standard reverse osmosis systems is its dedicated mineralisation stage.

Reverse osmosis removes many dissolved substances, including naturally occurring minerals. The Balance cartridge adds selected minerals back into the treated water, particularly calcium and magnesium.

The manufacturer's indicative water-quality values are:

Parameter	Expected value
pH	7–8.5
Total mineral content	60–80 mg/L
Calcium	10–15 mg/L
Magnesium	4–6 mg/L
Sodium + potassium	<5 mg/L
Hydrocarbonates	30–60 mg/L
Chlorides	<5 mg/L

These figures are based on specified test conditions, including an inlet water temperature of 20°C. Mineral content may vary with seasonal temperature changes and water consumption. The first glass drawn after a period of standing may also have a higher mineral concentration.

Installation requirements

The Ecosoft PURE Balance is designed for connection to a suitable cold mains water supply.

The standard non-pumped version requires an incoming water pressure of 3–6 bar.

Installation also requires:

• A suitable cold-water supply connection.

• A drain connection for concentrate water.

• Space beneath the sink for the filtration assembly and storage tank.

• A suitable location for the dedicated drinking-water tap.

The system is supplied with the necessary connection components listed above. Installation should follow the manufacturer's instructions, and all connections should be checked for leaks before normal use.

If your household water pressure is below the required range, consider the Ecosoft PURE Balance version with a booster pump instead.

Filter replacement and maintenance

Regular replacement of the filtration cartridges is essential for maintaining water quality and protecting the reverse osmosis membrane.

GroAqua offers compatible PURE Balance replacement filter options:

• PURE Balance set of 5 replacement filters: For routine filter maintenance without replacing the membrane.

• PURE Balance set of 6 replacement filters with membrane: A more comprehensive replacement option that includes the membrane.

Replacement intervals depend on incoming water quality, household consumption and operating conditions. Follow the manufacturer's maintenance recommendations and replace cartridges when required.

Monitoring the treated water using a suitable TDS meter can also help assess reverse osmosis membrane performance. TDS readings are useful for monitoring changes in dissolved solids, although they do not identify individual contaminants or prove that water is microbiologically safe.

Is the Ecosoft PURE Balance right for your home?

The PURE Balance is particularly suitable for households looking for a domestic reverse osmosis water filter with a more developed mineralisation stage.

It is a good option if you want:

• A dedicated supply of purified drinking water.

• Six-stage under-sink reverse osmosis filtration.

• A higher-capacity 75 GPD membrane.

• Reduced water waste through AquaGreen technology.

• Calcium and magnesium added back into purified water.

• A storage tank for convenient access to drinking water.

• A system that does not require electricity or a booster pump, provided mains pressure is sufficient.

For households with lower incoming water pressure, the pumped PURE Balance model may be a better choice.

Why choose Ecosoft PURE Balance?

The Ecosoft PURE Balance combines reverse osmosis purification with specialist mineralisation and water-efficiency technology.

Its 75 GPD membrane, AquaGreen cartridge and Balance mineralisation stage make it a strong option for households looking for more than a basic under-sink water filter.
