How does a reverse osmosis system work?

Reverse Osmosis is a technology modified from nature for reliable water filtration. It is comparable to an extremely fine filtration (0.0001 µm).

In a reverse osmosis system, tap water is pressed under pressure against a synthetic semi-permeable membrane that only lets through the very small water molecules, but not impurities in the starting water due to their molecular size.

As a result, very pure water is achieved through reverse osmosis on the one hand - the osmosis water - and separately on the other side of the osmosis membrane the waste water, which is flushed into the drain.

The pressure required for the physical process of reverse osmosis is created either by the hydraulic pressure of the tap water or by a pressure pump built into the osmosis system.


What is filtered out of the water by a reverse osmosis system?

A reverse osmosis system enables the most comprehensive filtration of all unwanted substances contained in drinking water, such as lime, nitrate, phosphate, heavy metals (lead, cadmium), bacteria and viruses, chlorine, hormone and drug residues, asbestos, pesticides, uranium, microplastics, softeners and long-lasting chemicals compounds such as PFAs and PCBs. A reverse osmosis system achieves almost 100% purification of the drinking water. No other water filter technology in the household can do this. During filtration using a reverse osmosis system, no additives, salts or chemicals are added to the water.

Reverse osmosis systems have a long service life and require little maintenance, since the membrane of the reverse osmosis system constantly cleans itself during operation. So you can be sure that the filter stages of your reverse osmosis system do not release any retained pollutants back into the filtered water: they are simply washed away with the water that flows in afterwards.

So much choice - which is the right reverse osmosis system for your needs?

Reverse osmosis system with or without a tank? With mineralization and energizing or without? A premium water filter like the iWater, or the reverse osmosis bestseller Zen Flow. Or would you prefer an entry-level model like PuriFive?
