Reverse Osmosis Product Selector

What will you use your system for?

Reverse Osmosis produces the clearest, cleanest water available, taking out up to 99% of contaminants - making it ideal for a number of different uses. Apart from domestic drinking water, it's perfect for commercial use in window cleaning, food and drink processing and dentistry for instance, or in aquatics, where it minimises algae growth and aquarium maintenance.

Step 2

How many stages do you need?

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.

4 stage reverse osmosis system

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.

5 stage reverse osmosis system

A mid-range system offering pumped and unpumped options and an additional GAC carbon pre-filter to reduce stress on the carbon block for dechlorination. The best choice if you’re using the water for more than just drinking.

6 stage reverse osmosis system

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 RO.

Step 3

Pumped or unpumped?

Your mains water pressure is crucial for your Reverse Osmosis system. It needs an optimal pressure of 80PSD (5.5BAR). and if it's less than 40PSI (2.75BAR) you'll need a booster pump for the system to work. Check yours with your utliity company before deciding whether or not you'll need a pump. If you have selected a 4 stage system, you will need to select unpumped and add a pump in the accessories section.
