Under sink reverse osmosis water filter providing ambient filtered water. This filter uses the latest side stream reverse osmosis technology. This new technology dramatically reduces the amount of wasted water to a 1:1 waste to pure ratio. This machine has an LED display, with end of life filter alerts and shows what the unit is doing in that moment in time.

This water filter will removed 94 - 99% of the contaminants in your drinking water including, chlorine, heavy metals, fluoride, nitrates, phosphates and a long list of other contaminants. Leaves your water as pure as you can get from an under-sink filter. This is the latest technology designed to save water and  increase time period for the installation of consumables.

This unit is installed with a a storage tank under your sink and an drinking water tap on your worktop. The system is fully automatic, it fills the water storage tank and stops. Then when you draw water from the tap the system starts up and makes more pure water to refill the storage tank 

What does this new membrane technology mean to me? Environmentally friendly, reduced waste water means less water passing through filters, which in turn means increased filter life and reduced replacement filter costs.

This system has quick fit filters. The pre and post filters are simple twist and click filters, allowing a quick and easy filter change, without any hassle with taking a filter out of a housing using a spanner. All that is needed is a twist and click action, allowing your to change your filters in a much quicker time.

This system has a 5 stage filtration process:

  • Stage 1: Polypropylene 5 micron particle filter (Twist and click filter)
  • Stage 2: Granular activated carbon filter (Twist and click filter)
  • Stage 3: Sprayed 1 micron particle filter (Twist and click filter)
  • Stage 4: Side Stream reverse osmosis membrane
  • Stage 5: Post taste and odour removal filter (Twist and click filter) 


  • Stages 1, 2, 3 and 5 will need changing approximately once a year, but the system will advise you when they require changing.
  • Stage 4 needs replacing at least every 18 months, but can exceed 48 months dependant upon the quality of your mains tap water
