At the heart of Grayl purification systems is an advanced activated carbon filter responsible for the ion exchange process. As a result, dirty water is softened, purified, iron and manganese levels are reduced, and the taste of water is also improved thanks to the use of activated carbon. Unlike ordinary mechanical filtration, the Grayl filter uses electroabsorbent components capable of removing submicron pathogens and inorganic contaminants.

During the "pressing of water" processes of electrohesis and ion exchange take place, which create an effective submicron trap for pathogens (viruses, bacteria and parasitic protozoa). The filter consists of multiple layers of finely powdered activated carbon, responsible for trapping toxins, i.e. chemicals and heavy metals. The filter also contains zeolites with silver ions, which are natural antimicrobial agents, responsible for inhibiting the growth of bacteria and improving the taste of water.

Thelife of the carbon filter is 150 l (about 300 uses) or 3 years from the first use. Water with a high content of silt, sediment and tannins can reduce the performance and life of the filter. At the end of its life, the filtration time may increase to 25-30 seconds, but still providing effective protection against pathogens compacted in dirty water. Properly stored unopened purification cartridge has a life span of 10 years.
