600 GPD Tankless 7-Stage Under-Sink RO System

This high-capacity, tankless under-sink reverse osmosis system delivers up to 600 GPD with a water-efficient 2:1 pure-to-drain ratio. A 7-stage composite filtration design targets PFAS, nitrates, fluoride, heavy metals, TDS, rust, sediment, and organic matter for cleaner, great-tasting water. Space-saving, quick twist-and-pull filters and FCC-listed electronic components support an easy, reliable setup.

Key Benefits & Performance

• High output: up to 600 gallons per day; fills a 200 ml cup in about 8 seconds.
• Water efficient: 2:1 pure-to-drain ratio to help reduce wastewater.
• Tankless, under-sink design frees cabinet space.
• Quick, twist-and-pull filter changes—no bulky tank to manage.
• FCC-listed electronic components for compliance and safety.

7-Stage Composite Filtration

The system uses two integrated filter cartridges to deliver multi-stage performance:

• CF cartridge: Sediment PP membrane + activated carbon block to reduce rust, sediment, and organic matter, improving taste and clarity.
• MRO cartridge: 0.0001-micron RO membrane + sediment PP membrane + activated carbon block + PET pleated membrane to reduce TDS, salt, nitrates, PFAS, fluoride, and heavy metals.

Together, these stages provide thorough contaminant reduction while maintaining fast, consistent flow.

Setup & Maintenance

• Tankless under-sink installation with compact footprint.
• Follow the included manual for plumbing connections and initial flushing.
• Twist-and-pull filter swaps are tool-free; replace as needed based on use and water quality.

Why it's important for longevity?

Water quality is a daily determinant of long-term wellness. Over years, even low-level exposure to contaminants such as PFAS, nitrates, fluoride, and certain heavy metals can add up in ways that may stress the body’s filtration and detoxification systems. A reverse osmosis system with a 7-stage composite design meaningfully lowers this exposure by reducing a broad range of dissolved and particulate impurities. That reduction helps protect the taste and clarity of drinking water, which in turn makes consistent hydration easier—an underappreciated foundation for energy, cognition, temperature regulation, and physical performance.

The 2:1 pure-to-drain ratio supports sustainability by decreasing wastewater compared with many conventional RO units, helping you maintain a daily clean-water habit with less environmental cost. A tankless, under-sink format also saves space, reduces stagnation risks associated with storage tanks, and maintains a steady flow for cooking and drinking. Finally, simple, twist-and-pull filter changes lower friction for upkeep, increasing the odds you’ll keep the system performing optimally over the long term. In short, by improving taste, reducing a wide spectrum of contaminants, and simplifying maintenance, this system supports a practical, daily hydration routine—one of the most reliable, compounding behaviors for long-term health.

Frequently Asked Questions

• What contaminants does this system reduce? The multi-stage design targets PFAS, nitrates, fluoride, heavy metals, TDS, rust, sediment, and organic matter.
• How fast is the flow? It produces up to 600 GPD and can fill a 200 ml cup in about 8 seconds under typical conditions.
• What is the pure-to-drain ratio? The system operates at a 2:1 pure-to-drain ratio, helping conserve water compared with many traditional RO systems.
• Does reverse osmosis remove beneficial minerals? RO reduces dissolved minerals along with unwanted contaminants. If desired, you can remineralize water after filtration (remineralization media not included).
• How do I change the filters? Turn off the water supply, relieve pressure, then twist and pull the cartridges to replace. Refer to the user manual for steps and recommended maintenance.
