Product highlights
KTF-662 Plus is the most advanced, high-capacity solution, delivering softened, purified water from every tap and appliance in your luxury home.
01
The filtration core combines high-grade MAX CLEAN media and MAX SOFT resin with a 0.01µ Ultrafiltration (UF) membrane and an integrated UV light. This robust configuration is scientifically designed to significantly reduce chemical contaminants, scale-causing minerals, and provides an enhanced safety barrier against microorganisms.
02
Extreme Flow & Softening Power Built to handle the highest simultaneous water demands, the system delivers a powerful 8.8-11.0 GPM flow rate. Its high-performance resin is tested to reduce water hardness up to 70 GPG, protecting expensive fixtures and improving soap efficiency.
03
The intelligent electronic valve precisely controls 6 programmed cycles—including backwashing and regeneration—based on your actual water consumption, which optimizes salt/water use and maximizes the effective lifespan of the filtration media.Karofi water purifiers deliver output water certified to meet the National Technical Regulation QCVN 6-12010/BYT – the highest standard for bottled drinking water in Vietnam. Each product batch undergoes independent testing by the National Institute of Occupational and Environmental Health, ensuring complete peace of mind for direct consumption by you and your family.
