Compact RO System for residential use


  • Flow rate: up to 280 liters or 75 gallons per day
  • Operating pressure: 1.4 - 4 bar / 20 - 60 psi

The 75GPD is a small, point-of-use reverse osmosis drinking water system ideally suited for residential applications.

The 5-stage system is made up of a 5 micron sediment pre-filter, a second stage GAC carbon filter, followed by our patented 2-in-1 design 1 micron GAC filter, designed for optimal RO membrane protection. The water then filters through a high-grade RO membrane and passes through a post-carbon filter for final polishing and to remove any remaining taste or odor.

The system comes complete with a chrome-plated plastic faucet. Optional booster pump is equipped with all aluminum end caps, providing better thermal management and longer service life.  Optional ROWave™ RO storage tanks are also available.
