RO systems feature a number of stages, and choosing the right one depends on the space available, your water pressure and whether or not you want to add essential minerals back into the water.
- Four Stage Reverse Osmosis Systems - ideal if you have limited space under your sink and our least expensive RO system. Performs as well as larger systems, but only has two pre-filters with no pumped option.
- Five Stage Reverse Osmosis Systems - mid-range system offering pumped and unpumped options and an additional GAC carbon pre-filter which improves the dechlorination of water and better protects the RO membrane from chlorine damage.
- Six Stage Reverse Osmosis Systems - our best and more popular system, with pumped and unpumped options - the extra stage is a remineralising filter, which puts back essential minerals like Calcium, Magnesium, Sodium and Potassium which are taken out during the RO process.
