What is Reverse Osmosis (RO) and How You can Benefit From It

Benefits of RO water infographic by Reliance Home Comfort

Reverse Osmosis (RO) is a high quality water filtration process that reduces impurities from drinking water. The process forces water through a specialized semi-permeable membrane – it’s very thin, approximately the thickness of cellophane. This allows the filtered water to be passed through leaving almost all of the impurities behind making the water clean and refreshing.

How Reliance’s 4-stage reverse osmosis (RO) system works

Cold water is processed through pre-filters and passed through the semi-permeable membrane

  1. Sediment pre-filter removes larger particles
  2. Carbon pre-filter removes chlorine
  3. Pressure is applied to force water through semi-permeable membrane to reduce total dissolved solids (TDS)
  4. Final rinse – water in the storage tank passes through final carbon filter, ready for your use


  • Capacity: Over 189 litres per day
  • Filter replacement: easy quick-change filters that can be replaced without complicated tools, or messy cleanup
  • Replacement filters: included in rental program and sent to you when it’s time to replace
