  • 600 GPD High Flow & Water Saving: The RO600ORB under sink reverse osmosis system delivers a powerful 600 GPD flow rate with a 2.5:1 pure water to drain ratio, reducing water waste by up to 400% compared to conventional systems. With its built-in booster pump, the system provides a steady flow of up to 0.4 GPM and can fill an 8 oz cup in less than 10 seconds
  • Advanced Filtration Technology: This tankless RO system reduces up to 99% of over 1,000 contaminants, including chlorine, fluoride, lead (up to 98%), arsenic, asbestos, sodium, calcium, sand, and odors. With a TDS rejection rate up to 99%, the high-efficiency RO membrane and multi-stage filters deliver clean, great-tasting water for drinking and cooking. Actual performance may vary based on source water and temperature
  • Smart Filter Life Reminder: Built-in LED indicators track filter status in real time: white for normal, blinking white when less than 10% life remains, and red when replacement is needed. Compatible replacement filters: FCF600 (composite filter) and MRO600 (RO membrane). Stay on schedule to maintain peak performance
  • Space-Saving & DIY-Friendly: The tankless design saves up to 70% of under-sink space. Twist-and-lock filters allow for quick, tool-free replacement without shutting off your water supply. Automatic self-cleaning function flushes the RO membrane after 24 hours of non-use to help extend its life
  • Lifetime Support: Constructed with BPA-free materials. Backed by a 1-year limited warranty upon registration and lifetime customer support from Georgia, USA. Clear instructions and video guides help ensure an easy setup experience. An eco-conscious solution to reduce plastic waste by using a home reverse osmosis water filter system
