Why Choose Our Product


  • Baby Safe Water

    7-stage Purification makes the water so pure that it becomes safe even for babies. It removes heavy metals, chemicals, pesticides, and disease-causing microorganisms.

  • Excellent Protection

    The RO+SCMT ensures maximum protection. SCMT (Silver Charged Membrane Technology) provides second level of purification that prevents any potential secondary level contamination. It’s proven that RO+SCMT provides far superior water purification compared to RO+UV, RO+UF, and RO+MF

  • Mineralizer Technology

    adds essential minerals like calcium and magnesium into the water which makes it taste fresh and natural. It also balances pH, an essential requirement for healthy drinking water

* Flow rate depends on variable factors such as feed water pressure, feed water characteristics and condition of the membranes and filters.  
** Recovery and TDS reduction percentages also depend on variable factors such as life and condition of the membranes and filters, feed water pressure, feed water characteristics.  
*** If input pressure exceeds 30 psi, a pressure reducing valve needs to be installed at the feed line. If the pressure is lower than 7 psi, a booster pump needs to be installed.  

**Design, feature and specifications mentioned are subject to change without notice.
