Ecosoft Underbench RO system

Ecosoft P'URE reverse osmosis filters represent combination of innovative technologies and natural processes that provide delicious water with stable mineral content.

Ecosoft P'URE AquaCalcium reverse osmosis filter removes 99.8% of pollutants from water and provides delicious, fresh and soft drinking water enriched with calcium.

Key features

  • AquaCalcium mineralizer enriches treated water with calcium
  • Replicates the natural conditions of water percolation through mountain rocks
  • Provides stable content of minerals in the purified water — 55–65 mg/L
  • Fresh, soft, and natural taste of water
  • Water with calcium is especially recommended for teenagers and elderly people
  • Manufacturer's assurance — all products have the necessary approvals for domestic usage and undergo factory acceptance tests
  • Ecomerce pack

Quality of mineralized water*

  • pH 7-7.5
  • Total mineral content - 55-65** mg/L
  • Calcium - 10-15 mg/L
  • Magnesium <1 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
