Core Features & Technology

  • HW800 AlkaPro Technology: Expert Filtration for Superior Taste
    Discover what truly clean water tastes like with Honest Water’s advanced 7-Stage High-Precision Filtration. Engineered with an ultra-fine 0.0001µm (micron) filter, our system removes heavy metals, dissolved solids, chlorine, and other everyday contaminants. The natural Coconut Carbon Block—crafted from real coconut shells—brings out a smoother, fresher flavor in every sip.
  • Efficiency Redefined: Instant, Tankless Design
    Honest Water delivers instant, tankless filtration for fresh, clean water on demand. Our compact design saves up to 70% more space than bulky tank systems, while high flow rates ensure you get pure water quickly and effortlessly.
  • Eco-Conscious Innovation: Save Water, Reduce Waste
    Be part of the eco-friendly revolution with the HW800 AlkaPro. Its efficient 2:1 Low Drain Ratio uses far less water than standard R.O. systems—producing 2 cups of pure water for every 1 cup drained. That’s up to six times more water saved, all while delivering clean, refreshing hydration you can feel good about.
  • Positive Environmental Impact
    When you choose Honest Water, you’re choosing a cleaner planet. Our reverse osmosis systems replace single-use bottled water, helping cut down plastic waste and shrink your carbon footprint—one refreshing sip at a time.
  • Integrated Alkaline Technology
    This system features built-in alkaline remineralizing technology, enriching your water with beneficial minerals while keeping the design simple and efficient. With fewer connections required, the risk of leaks is greatly reduced—ensuring safer, worry-free performance.
  • Auto R.O. Flush Keeps Your Filter Fresh
    The HW800 Auto Flush system keeps your R.O. membrane clean by automatically washing away trapped impurities—preventing clogs and extending the life of your system. You don’t have to do a thing! If you notice a brief flushing sound and see the filter lights blink now and then, that’s your system hard at work.
  • Safety & Quality Assurance
    With a leak-free, lead-free water path built to NSF372 standards, HW800 is engineered for your peace of mind. Every drop is filtered through a system designed for safety, reliability, and the well-being of you and your family.
  • Certifications
    The HW800 AlkaPro is Tested and Certified by NSF International against NSF/ANSI Standard 58 for TDS Reduction and for materials and structural integrity requirements.
