Technologies

Multi-Layered
Hyper Filtration
Technology

Step 1

Sediment Filter for Particle Removal

The mains water first comes to the pre-filter with a pore size of 5 microns. The task of this high-tech filter is to remove coarse impurities in the water, i.e. sediments such as dust, sand, algae, insects, etc. down to 5 microns. Over 5 microns in size, some microorganisms, dissolved chemicals and minerals can still be found in the water, which is thoroughly clarified by the sediment filter, where suspended particles and bacteria are retained in the water.

Step 2

Pre-Carbon Filter for Removal of Chlorine and Organic Matter

The water comes to the block carbon filter. The task of the block carbon filter is to remove organic substances that cause bad taste, odour and colour, as well as chlorine in the water and, if any, gas odours. It makes the water more delicious, clear and odourless. It provides advanced filtration by filtering the water filtered by the sediment filter up to 5 microns with a sensitivity of 1 micron.

Step 3

Hyper Filtration for Advanced Treatment

The semi-cleaned water comes into the hyper filtration cartridge, which is the heart of the system. Hyper filtration has a semi-permeable membrane structure and works with a pressure of at least 2.5 atmospheres. Its pores are between 8-10 angstrom. On hyper filtration; Thanks to the semi-permeable membrane with pores as one millionth of a millimetre, heavy metals such as lead, mercury, nitrate, arsenic, copper, bacteria, lime and other chemical pollutants dissolved in water cannot pass.
Hyper filtration allows the passage of water molecules, while providing flawless filtration of dissolved chemicals, microorganisms and harmful minerals. Only water molecules and anions and cations beneficial for human health pass through this filter. The water coming out of hyper filtration is real healthy drinking water. The daily water yield of hyper filtration is approximately 350 litres. The healthy drinking water obtained from the membrane comes into a 12 litre stainless steel tank and is stored there.

Step 4

Alkaline Filter / To regulate the taste and odour of water

The water from the tank to the tap finally comes to the carbon filter to gain flavour. The task of this filter is to prevent the formation of microorganisms by removing odour-causing substances. Water in this filter; the taste is improved. At the last stage, the water comes to the tap. Thus, healthy and fresh Rainwater water is ready to drink safely.

FAQ

General Questions

We have listed the answers to the most frequently asked questions. You can find the answers to your questions on this page.

Why should I use a water purification device?

It filters harmful substances such as chlorine, heavy metals, viruses, bacteria, and chemical residues that may be present in tap water, providing cleaner and more palatable drinking water. It also helps reduce plastic bottle usage, contributing to both the environment and your budget.

Are water purification devices healthy?

Yes. With the appropriate technology and maintenance, it makes the tap water safe to drink. However, device performance and the initial quality of the water can affect the result.

Can I drink the purified water directly?

In most models, yes. RO systems in particular purify water from bacteria and viruses. However, device maintenance and filter quality are important.

Does it affect water pressure?

Reverse osmosis systems may experience a slight drop in water pressure, but this usually does not cause a significant problem in the home. If the pressure drop is severe, professional assistance is recommended.

Should I choose a pumped or non-pumped device?

If the mains water pressure in your home is 4 bar or above, a device without a pump is sufficient. If the pressure is below 4 bar, devices with pumps are recommended; these also extend the life of the membrane.

What about filter life and maintenance intervals?

In open-tank models, the front three filters should generally be replaced every six months, while in closed-tank devices they should be replaced once a year. The reverse osmosis membrane filter is replaced every 12–24 months. Alkaline, mineral or post-carbon filters are replaced on average every 12 months.

What should I look out for when buying a device?

Use of NSF, FDA or TSE certified filters Access to spare parts and service network Warranty period and conditions Pressure and contamination level of your inlet water Usage capacity (e.g. is an 8-litre or 12-litre tank sufficient?)
