Water Purification System (RO5)

Permatech RO5 Water Purification System is designed to be neatly installed in the cabinet under the sink. It doesn’t take up any countertop space and comes with its dedicated modern faucet.

With Permatech’s unique twist-off design, replacing your filter will be fast, easy and won’t require any tools.

Reverse Osmosis is a purification process for getting the smallest particles of impurities out of your water by passing it through a membrane. This system has the ability to purify close to distilled water.
This system produces a steady stream of high-quality water at a fast rate, which makes it very convenient to install at your home, office or whereever clean drinkable water is needed.



With our Permatech water purification system (RO5), you’ll get the quality of water that you can trust.

This system uses water pressure to reverse a natural physical process called reverse osmosis. Water, under pressure, is forced through a semi-permeable membrane where minerals and impurities are filtered out. Clean drinking water goes to the storage tank (12 liters), while the impurities are drained out.

This reverse osmosis system will provide you with a continuous supply of clean, delicious water for drinking, cooking and other uses. Having premium quality RO water at hand eliminates the need to buy bottled water.

Product description:

Permatech (RO5) is a  Compact Molecular Water Purification System, based on reverse osmosis with prefiltration, RO membrane closed in housing, and postfiltration. All stages are enclosed in a compact and ergonomic casing designed for modern kitchens.

Permatech (RO5) consists of innovative and patented replaceable filter cartridges, which possesses an increased filtration capacity and a Quick Disconnect design for easy replacement without the need to use any tools.

Prefiltration is followed by a molecular filtration technology which filters the source water up to 0,0001 microns and removes impurities such as heavy metals, radioactive and carcinogenic elements. The final stage uses a mineralization technology which reintroduces beneficial minerals into your water.

To prevent water waste, an automatic shut-off valve closes when the RO faucet is closed and the storage tank is full.

Stages of Water Filtration System:


Stage 1: Heavy Sediment Filter, double layered Yarn & Spun (5 microns rating)

High quality cartridges, manufactured with Polypropylene thread outer layer and Polypropylene Spun for the inner layer which makes these filter capable of a double filtration performance.

Their structure ensures very effective removal of mechanical impurities (big and smaller particles), such as: sand – rust – river mud – fluvial silt – pollen – microorganisms – carbon dust – other precipitates


Stage 2: Activated Carbon

High quality cartridges, containing granular activated carbon.

  • Cartridges improve water taste and smell by effectively removing:
  • Organic impurities (microorganisms, bacteria, funghi)
  • Mechanical impurities
  • Chlorine and its poisonous compounds
  • Lead and toxic heavy metals
  • Pesticides, detergents and phenols


Stage 3: Sediment-Carbon

High quality, patented sediment-carbon cartridges, manufactured with polypropylene thread and activated carbon.

Their structure ensures very effective removal of various impurities, such as:

sand – rust – river mud- fluvial silt- pollen – microorganisms- chlorine and its poisonous derivatives

lead and other heavy metals- organic compounds- pesticides – detergents – phenols


Reverse Osmosis Membrane

Stage 4: Osmotic Membrane

Osmotic membrane is a barrier for organic and non-organic contaminants, solids dissolved in water, heavy metals, radioactive and carcinogenic elements. It only allows water particles in, as its porosity is similar to the size of water particle, that is 0,0001 micrometers.



Stage 5: In-Line Mineralizer

Mineralizing MIN-1L cartridges saturate water with mineral salt ions. The appropriate dissipation of minerals contained in the cartridge filling causes their dissolution in water. This, in turn, improves the taste and smell of water.
