By adding this inline filter as the final stage in an RO system, you'll get the optimum benefit of the alkaline-mineral media. With this addition, you turn your existing reverse osmosis system into a spring water source with all alkaline and antioxidant qualities. This alkaline antioxidant filter provides abundant active hydrogen. It also increases the reduction power by increasing pH, making small water clusters and providing beneficial minerals such as calcium, magnesium, potassium and sodium.

Product features:

  • This alkaline pH filter for reverse osmosis system is an inline cartridge with mineral balls & calcite media. The alkaline filter improves the pH value of the RO water which could be lightly acid after the reverse osmosis process. It also gives back healthy minerals such as ionized calcium, magnesium, sodium, and potassium ion, which were taken away during the water purifying process.
  • Capable of increasing the pH value of the RO water by 0.5 to 0.8, which helps minimize the fluctuations of your body's pH.
  • The minerals from the alkaline filter are natural calcium, magnesium, sodium, and potassium ions, which can be absorbed 100% by the human body. These ions are structurally smaller molecules which help the body take in more water and replenish lost water quickly. They also make the water cleaner and healthier.
  • Improves the qualities of clean water by adding necessary minerals for proper human development and health, such as calcium, magnesium, sodium, potassium and others readily found in natural mineral water.
  • Mainly installed with RO systems to complement their absolute filtration qualities
  • Filter life: 6 months or 1500 gallons, whichever comes first.

    Fits most RO systems, including name brand models.
