Domestic Reverse Osmosis Water Filter Systems

Enjoy convenient access to purified drinking water at home with the Ecosoft Standard PRO Reverse Osmosis System with Mineralisation. Designed for installation beneath the kitchen sink, this five-stage domestic water filtration system combines sediment filtration, activated carbon treatment, reverse osmosis membrane technology and a final mineralisation stage. The system is designed to reduce a wide range of unwanted substances in mains water, including suspended particles, chlorine and dissolved impurities. Its 50 GPD reverse osmosis membrane provides a nominal production capacity of up to 190 litres per day, while the integrated storage tank keeps purified water available when you need it. A final mineralisation stage adds minerals back into the treated water, helping to improve its taste after reverse osmosis filtration. With no electrical supply or booster pump required, the Ecosoft Standard PRO is a practical under-sink drinking water solution for households with suitable mains water pressure. Five-stage reverse osmosis water filtration The Ecosoft Standard PRO uses five stages of water treatment to provide a comprehensive domestic drinking water filtration process. Stage 1 – 5 Micron Sediment Filtration A polypropylene sediment filter captures suspended particles such as sand, rust, silt and other visible impurities. This initial filtration stage helps protect the downstream carbon filters and reverse osmosis membrane. Stage 2 – Granular Activated Carbon Filtration The granular activated carbon filter, made using coconut shell carbon, reduces chlorine and certain organic compounds that can affect water quality, taste and odour. It also helps protect the reverse osmosis membrane from chlorine exposure. Stage 3 – 1 Micron Sediment Filtration A finer polypropylene sediment filter removes smaller suspended particles before water reaches the reverse osmosis membrane. Stage 4 – Reverse Osmosis Membrane The 50 GPD reverse osmosis membrane is the main purification stage. It separates water into two streams: purified water, known as permeate, and a concentrate stream containing rejected dissolved substances that is discharged to drain. Reverse osmosis is particularly effective at reducing dissolved salts and many other dissolved impurities. Actual performance depends on the incoming water quality, operating pressure, temperature and condition of the membrane. Stage 5 – Mineralisation After reverse osmosis, water passes through the mineralisation cartridge. This adds minerals back into the purified water, helping to improve its taste and provide a more balanced drinking-water profile. Designed for everyday drinking water at home The Ecosoft Standard PRO is designed as a point-of-use water purification system, supplying treated drinking water through its own dedicated kitchen tap. The integrated pressure storage tank holds purified water so it is available on demand, rather than requiring the membrane to produce water at the full drinking-tap flow rate. The system operates without electricity, making it a straightforward solution for homes with adequate incoming water pressure. Key features and benefits Five-stage filtration: Combines sediment, activated carbon, reverse osmosis and mineralisation technologies. 50 GPD membrane: Nominal production capacity of approximately 190 litres per day under rated conditions. Mineralisation stage: Adds minerals back into the purified water to help improve taste. Dedicated drinking water tap: Supplies treated water separately from the standard kitchen tap. Integrated storage tank: 12-litre total tank capacity, with up to 7 litres of usable water. No electricity required: The standard model operates using mains water pressure without a booster pump. Under-sink installation: Designed to fit beneath a domestic kitchen sink. Replaceable cartridges: Routine maintenance can be carried out by replacing the appropriate filter elements.

Stage 2 – Activated Carbon Pre-Filtration The second stage uses a carbon block to reduce residual chlorine and selected compounds that can affect water taste and odour. This stage also helps protect the reverse osmosis membrane. Stage 3 – Reverse Osmosis Membrane The reverse osmosis membrane is the main purification stage. Its semipermeable membrane reduces dissolved salts, minerals and other dissolved substances as water passes through it. Stage 4 – Activated Carbon Post-Filtration The final carbon block helps improve the taste and odour of the purified water before it reaches the dedicated drinking-water tap. The filtration stages are supplied through two replacement cartridges: Z1-E020-C: Combined 3-in-1 sediment and carbon filtration cartridge. Z1-E020-M: Reverse osmosis membrane cartridge, incorporating the membrane and post-filtration arrangement described in the manufacturer's system design. High-Capacity Tankless Reverse Osmosis Traditional domestic reverse osmosis systems generally use a pressurised storage tank to hold purified water before it is dispensed. The SPECTRUM PURE Z1-E020 uses a direct-flow design, producing purified water when the drinking-water tap is opened. Its rated performance includes: Performance parameter Specification Nominal daily production 3,000 L/day Rated product flow 2 L/min Equivalent hourly flow 120 L/hour Nominal salt rejection 93% Nominal recovery 65% Storage tank None The 3,000 L/day figure is a nominal production rating, not a guaranteed household daily output. Actual production depends on water pressure, temperature, incoming TDS and other feed-water conditions. Compact Under-Sink Installation The Z1-E020 is designed for installation beneath a kitchen sink or in another suitable location close to the drinking-water outlet. Its compact dimensions are: 130 × 397 × 376 mm (W × D × H) The tankless configuration makes it particularly useful where cupboard space is limited. The system uses push-fit connections and a dedicated stainless-steel drinking-water tap. It also requires a connection to the cold-water supply, household drainage and an electrical supply through the supplied power transformer. Water Quality and Operating Requirements The SPECTRUM PURE Z1-E020 is designed for municipal water supplies. The manufacturer's installation manual specifies the following operating conditions: Parameter Specification Feed-water pressure 1–4 bar Feed-water temperature 5–38°C Maximum feed-water TDS 500 mg/L (ppm) Maximum feed-water turbidity Less than 1 NTU Nominal salt rejection 93% Nominal water recovery 65% Water supply Municipal Electrical input 100–240 V AC, 50/60 Hz Electrical output 24 V DC, 5 A Power consumption 120 W Sound level Approximately 60 dB Do not operate the system above 4 bar. A pressure-reducing valve must be installed on the water supply if incoming pressure exceeds the manufacturer's maximum. The system must be connected using the supplied power supply unit and must not be installed on a hot-water line. If the source water is microbiologically unsafe or of unknown quality, adequate disinfection is required before or after the system.

The system also has separate filter-life indicators for the 3-in-1 cartridge and RO membrane cartridge. The indicators change from blue to red as the cartridges approach the end of their programmed service life. A red indicator is a replacement reminder; the system may continue operating until the cartridge is replaced. After cartridge replacement, the relevant filter-life indicator must be reset according to the manufacturer's instructions. Replacement Filter Cartridges and Maintenance The Z1-E020 uses two dedicated twist-and-lock replacement cartridges. Replacement cartridge Function Manufacturer's suggested service interval Z1-E020-C 3-in-1 sediment and carbon pre/post filtration arrangement 6–12 months Z1-E020-M Reverse osmosis membrane cartridge 12–24 months These intervals are guidelines rather than guaranteed cartridge lifetimes. Actual replacement frequency depends on incoming water quality, daily consumption, sediment levels, chlorine, turbidity and hardness. Replace cartridges sooner if water quality deteriorates, the taste changes significantly or purified-water production falls noticeably. After replacing cartridges, reset the appropriate filter-life indicator and flush the new cartridges for approximately 5–10 minutes before returning the system to normal use.

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. Key features and benefits Six-stage filtration: Combines sediment, carbon, AquaGreen, reverse osmosis, mineralisation and carbon post-filtration. 75 GPD membrane: Nominal production capacity of approximately 280 litres per day. AquaGreen technology: Manufacturer-stated water recovery rate of up to 50%. Calcium and magnesium mineralisation: Adds selected minerals back into purified water. Improved drinking-water taste: Mineralisation and final carbon filtration help create a pleasant drinking-water profile. Integrated storage tank: 12 litres total tank capacity, with up to 7 litres usable capacity. Dedicated drinking-water tap: Supplies purified water separately from the normal kitchen tap. No electricity required: The standard version operates using mains water pressure without a booster pump. Flexible installation: Designed to support horizontal or vertical installation, subject to installation requirements. Replaceable cartridges: Routine servicing can be carried out using compatible Ecosoft replacement filters.

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 integrated booster pump helps provide the pressure needed for membrane operation, particularly in lower-pressure installations. Stage 5 – Balance Mineralisation After reverse osmosis, water passes through the dedicated Balance mineralisation cartridge. This stage adds calcium and magnesium back into the purified water, helping restore part of its mineral content and improve drinking-water 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 values are indicative manufacturer figures rather than 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 water reaches the dedicated drinking-water tap. AquaGreen technology – improved water recovery The PURE Balance incorporates Ecosoft's AquaGreen technology, designed to improve water efficiency during reverse osmosis filtration. Reverse osmosis systems discharge a proportion of incoming water to drain as part of the membrane separation process. AquaGreen technology is designed to achieve a manufacturer-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, operating pressure, temperature and system conditions. Mineralised drinking water with calcium and magnesium A key feature of the PURE Balance is its dedicated mineralisation stage. Reverse osmosis removes many dissolved substances, including naturally occurring minerals. The Balance cartridge adds selected minerals back into the purified water, particularly calcium and magnesium. The manufacturer's indicative mineralised-water profile is: 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 values are determined under specified test conditions, including an inlet water temperature of 20°C. Mineral content may vary with seasonal temperature changes and water consumption.

How the Ecosoft CROSS MAX Filtration System Works CROSS MAX uses a four-stage purification process delivered through two replaceable cartridges. Stage 1 – Sediment Prefiltration The first filtration stage reduces suspended particles such as sand, rust, silt and other sediment. This helps protect the downstream filtration components. Stage 2 – Activated Carbon Prefiltration The prefilter also contains activated carbon to reduce residual chlorine and selected organic compounds that may affect water taste and odour or damage the reverse osmosis membrane. Stages 1 and 2 are incorporated into the combined CPVCBDFRO prefilter cartridge. Stage 3 – Reverse Osmosis Membrane The 800 GPD reverse osmosis membrane is the principal purification stage. It reduces dissolved salts, mineral impurities and other dissolved substances as water passes through its semipermeable membrane. Stage 4 – Activated Carbon Treatment The system's final carbon filtration stage helps improve the taste and odour of the purified water. This is incorporated into the membrane cartridge assembly. The two replaceable cartridges are: CPVCBDFRO – combined sediment and carbon prefilter. CSVPDRO800 – 800 GPD reverse osmosis membrane cartridge with carbon filtration. High-Flow Tankless Reverse Osmosis Traditional domestic reverse osmosis systems generally use a pressurised storage tank to hold purified water before it reaches the drinking water tap. CROSS MAX takes a different approach. It produces purified water directly when the tap is opened, allowing customers to benefit from a high-flow RO system without allocating cupboard space to a separate storage tank. Its rated performance includes: Performance parameter Specification RO membrane capacity 800 GPD Rated direct-flow capacity 120 L/hour Rated flow rate 2 L/min Approximate 200 ml glass filling time 6 seconds Water recovery rate Up to 67% Purified-water TDS Typically 5–15 mg/L under specified conditions Storage tank None Actual output depends on inlet pressure, water temperature, feed-water quality and cartridge condition. Compact Under-Sink Installation CROSS MAX is designed to fit beneath a kitchen sink, making it suitable for modern kitchens where storage space is valuable. Its approximate dimensions are: 304 × 198 × 191 mm (H × W × D) The system has an integrated pump and requires an electrical connection. It also needs a cold-water feed, a connection to the household drain and a dedicated purified-water tap. The installation should include a pressure reducer at the inlet, as required by the manufacturer. Water Quality and Operating Requirements CROSS MAX is intended for use with suitable cold municipal tap water. The manufacturer's published feed-water limits include: Parameter Maximum / acceptable value Feed-water pH 6.5–8.5 Total dissolved solids (TDS) 1,500 mg/L Total hardness 500 mg/L as CaCO₃ Free chlorine 0.5 mg/L Total iron 0.3 mg/L Manganese 0.1 mg/L Feed-water temperature +5 to +30°C Inlet pressure Check current model documentation; published materials vary A pressure reducer is mandatory. The manufacturer identifies 3.5 bar as the optimal operating pressure in its installation and warranty guidance. Water outside the manufacturer's quality limits may require additional pre-treatment. The system should not be used to treat microbiologically unsafe water or water of unknown quality without appropriate prior disinfection. Purified Water Characteristics The manufacturer's published specifications indicate a typical purified-water TDS range of approximately 5–15 mg/L under specified conditions. Reverse osmosis reduces dissolved mineral content as part of its purification process. CROSS MAX does not include a mineralisation stage. If you want purified water with added calcium and magnesium, consider an Ecosoft PURE Balance system instead. Smart Operation and Automatic Flushing CROSS MAX includes electronic features designed to simplify everyday operation and maintenance. Automatic membrane flushing The system automatically flushes the membrane as part of its operating cycle. Manual flushing can also be initiated using the control panel. Cartridge replacement reminder The filter-life indicator tracks the remaining cartridge capacity and alerts the user when replacement is approaching. Leak detection The supplied leak sensor helps detect water leakage around the installation. Continuous-operation protection The system includes an overtime protection function. If it operates continuously for more than 10 minutes, it automatically stops water supply. The operating mode must be reset in accordance with the manufacturer's instructions. Replacement Cartridge Schedule CROSS MAX uses two dedicated replacement cartridges. Replacement cartridge Function Recommended replacement CPVCBDFRO Sediment and activated carbon prefilter Up to 2,000 L or approximately 12 months CSVPDRO800 800 GPD RO membrane cartridge with carbon filtration Up to 2,000 L or approximately 12 months Actual cartridge life depends on incoming water quality, daily water consumption and operating conditions. The electronic indicator helps monitor remaining filter capacity. After replacing cartridges, the system must be reset and flushed according to the installation manual.
