One Eight Filtration introduces the Ecosoft Standard 5 Stage Unpumped Reverse Osmosis part of our reverse osmosis range.

Ecosoft Standard 5 Stage Unpumped Reverse Osmosis is a technology that efficiently removes a large majority (over 98%) of contaminants from water. It works by pressurizing water through a series of smaller filters and a semi-permeable membrane, effectively trapping and eliminating all unwanted impurities.

Quality of mineralized water Ecosoft Standard 5 Stage Unpumped Reverse Osmosis

  • pH 7-7.5
  • Total mineral content – 55-65** mg/L
  • Calcium – 10-15 mg/L
  • Magnesium <1 mg/L
  • Sodium + potassium <5 mg/L
  • Hydrocarbonates — 30-50 mg/L
  • Chlorides <5 mg/L

* The indicators are determined under the following conditions: inlet water temperature is 20 °С, outlet water composition and filter operation parameters correspond to the recommended by the manufacturer, water consumption intensity is appropriate for a family of three. When the inlet water temperature decreases in winter, the mineral content in the treated water may be lower, and when the temperature increases in summer, it may be higher.

** After one hour or more standing time, the mineral concentration in the first glass of water may exceed the stated value
