Oasis Reverse Osmosis Filtration System



Oasis DP Underbench Reverse Osmosis System

Remove fluoride and chlorine from your water with Oasis under-bench reverse osmosis.. 

The process includes multiple phases: the water is subject to triple pre-filtration to eliminate impurities, pollutants, bad odours and flavours; subsequently it is channeled through the osmotic membrane where the reverse osmosis phenomenon takes place.

What is Reverse Osmosis?

Reverse osmosis the ultimate in water purification. Water pressure pushes against a semi-permeable membrane. The membrane allows water molecules through while impurities are flushed down the drain. This means that it is very effective in dealing with even the most difficult contaminants, including Nitrate, Arsenic, Fluoride, Salt and many others.

What are the benefits of Under-bench Reverse Osmosis?

  •  The very best in domestic undersink filtration and purification
  • Ultra Clean, Safe, Pure Water on tap for the whole family
  • Noticeably better tasting drinking water
  • Tea and Coffee will infuse better and have improved flavour
  • Tidy design for under sink use
  • A separate lead free drinking tap keeps the water safe all the way to delivery 
  • You will no longer need to buy bottled water, reducing your carbon footprint and plastic pollution 


  • A specially designed complete 6 stage reverse osmosis system for under bench use.
  • This unit does an excellent job of eliminating undesirable contaminants, like Nitrate, Fluoride and Salt. The remineralising cartridge then puts beneficial minerals back in.
  • The unit comes complete, including all required connections, a 16L pressure tank and separate drinking water tap
  • Oasis DP are specially designed for installation under the kitchen sink and come complete with an installation kit.
  • The unit is capable of producing up to 189 litres per day
  • Made with exclusively Made in Italy Components

The Oasis DP RO is a 6 stage unit

Stage 1: 5 Micron Sediment Filter
PP Melt Blown Polyspun Sediment Filter

  • The filter will remove sediment, rust and fine particles.
  • This filter is designed to protect the remainder of the system from particles
  • Life-span: 3-6 months. Max temperature: 45°C (113°F).

Stage 2: Granular Activated Carbon Purifier
CTO, Chlorine, Taste and Odour Reduction

  • This is a cartridge containing granular activated carbon to reduce chlorine (bad tastes, odours), herbicides, pesticides and traces of heavy metals.
  • Life-span: 3-6 months.
  • Max temperature: 45°C (113°F).

Stage 3: 5 Micron Carbon Block Filter/Purifier
Chlorine, Taste, Odour and Sediment Reduction

  • This is an activated carbon block filter/purifier which will filter sediment, rust and fine particles. It will also reduce chlorine (bad tastes, odours), herbicides, pesticides and traces of heavy metals.
  • Life-span: 3-6 months.
  • Max temperature: 45°C (113°F).

Stage 4: Reverse Osmosis Membrane
Membrane for the main impurity removal

  • The membrane has pores which are so small that only pure water makes it through to the other side, effectively removing undesirable contaminants like Nitrate, Fluoride, Arsenic and Salt.
  • Lifespan depends on the level of impurities in water and incoming pressure, but under normal circumstances the membrane is expected to last 2-4 years.

Stage 5: Carbon Post Filter

  • The carbon post filter’s main job is to give the water a final polish and improve the taste of the water after it has passed through the membrane and has been stored in the tank.
  • Life-span: 3-6 months. Max temperature: 45°C (113°F).

Stage 6: Re-Mineralize

The re-mineralizing cartridge designed to increase pH and reintroduce beneficial minerals like Calcium and Magnesium back into the water. The membrane cannot differentiate between ‘good’ and ‘bad’ substances so it removes both.
Life-span: 3-6 months.
Max temperature: 45°C (113°F).
