The G500 is an advanced continuous flow reverse osmosis system ideally suited for residential and commercial applications.

Stunningly compact and environmentally-friendly, the G500 purification system provides continuous, clean, fresh, great-tasting drinking water. The G500 system eliminates unpleasant taste and odor and removes chlorine and contaminants such as heavy metals, pesticides and chemicals.

Refined, re-imagined, and re-engineered, the G500 is an elegant all-in-one water purification system that is as much a work of art as it is a state-of-the-art purification system. The G500 is a must have for your home, office or restaurant!

The patented compact cabinet design uses high-grade molded plastics and makes maximum use of your under-counter space. The durable materials, premium-grade fittings and connections, along with functionality such as dry-run protection with auto-restart and automatic RO membrane flushing, ensure a long service life. Filter cartridges have unique built-in handles for easy removal and are self-aligning; simplifying the cartridge replacement process.

The G500 is a highly efficient water purifier and has a water recovery rate almost three times as high as industry standards (1:125L vs 1:3.25L). The system can produce up to 400 gallons of purified water per day and comes with dual pressure gauges for monitoring system pressure and incoming water pressure.

A 14-gallon RO storage tank is recommended for high demand usage exceeding 400 gallons per day.
