• Capacity: up to 75 gallons per day or about 280 L/day
• Number of purification stages: 6 stages (pre-filtration – membrane – post-filtration – mineralization)
• Storage tank volume: approximately 7 L of purified water
• Operating pressure: from 2 to 6 bar
• Permissible water temperature: +5…+35 °C
• Dimensions: compact design for under-sink installation
• Package contents: assembled system, replacement cartridges, mineralizer, connecting tubes, mounting hardware, drinking water faucet, instruction manual

Operating principle

1. Pre-filters retain mechanical impurities, chlorine, and chemical compounds.
2. The reverse osmosis membrane performs the main purification, removing up to 98–99% of salts, heavy metals, bacteria, and viruses.
3. The post-filter completes purification and improves the organoleptic properties of the water.
4. The mineralizer enriches the water with calcium, magnesium, and other trace elements for a natural taste.

Advantages

• Optimal balance of purification and mineralization – water free of harmful impurities but with a beneficial composition.
• Reliable Premium membrane – stable operation and long service life.
• Compact design – convenient placement under the sink.
• Protection of household appliances – reduced scale formation in kettles, coffee machines, and boilers.
• Easy maintenance – cartridge replacement requires no special skills.

FAQ – Frequently asked questions

• How often should cartridges be replaced? Pre-filters – every 6–12 months, membrane – once every 2–4 years, post-filter – once every 12 months, mineralizer – about once a year.
• What pressure is required for system operation? The optimal operating pressure is 2–6 bar.
• Is a pump required? A pump is recommended if the water supply pressure is below 2 bar.
• Can the system be serviced independently? Yes, the design allows easy replacement of consumables.
• What is the purpose of the mineralizer? It adds calcium and magnesium to purified water, improving taste and physiological value.
