Spare cleaning cartridge with a capacity of 250 l dedicated to the Grayl GeoPress filter bottle . Fitr for Grayl GeoPress filter bottles . In just 60 seconds, we can clean up to 2,000 ml of water taken anywhere on the earth. Removes 99.99% of viruses The Grayl GeoPress filter removes pathogens from the water, such as viruses, rotaviruses, bacteria, parasitic protozoa, pesticides, chemicals, heavy metals and micro plastics. The filter also improves the taste, smell and clarity of the water by removing sediment, silt and other contaminants. By using Grayl GeoPress, we can protect ourselves against viral hepatitis, salmonella, dysentery, cholera and other deadly diseases . Cleans, softens and improves the taste The heart of Grayl's purification systems is an advanced activated carbon filter responsible for the ion exchange process. As a result, dirty water is softened, purified, the levels of iron and manganese are lowered, and thanks to the use of activated carbon, its taste is also improved. Unlike conventional mechanical filtration, the Grayl filter uses electroabsorbent components capable of removing submicron pathogens and inorganic contaminants. During the "pressing of water" electrohesion and ion exchange processes take place which create an effective submicron trap for pathogens (viruses, bacteria and parasitic protozoa). The filter consists of many layers of finely powdered activated carbon , which are responsible for trapping toxins such as chemicals and heavy metals. The filter also contains zeolites with silver ions, which are a natural antimicrobial agent responsible for inhibiting the growth of bacteria and improving the taste of water . Time of use The lifetime of the carbon filter is 250 l (approx. 350 uses) or 3 years from the first use. Water with a high silt, sediment and tannin content can reduce the performance and life of the filter. At the end of the service life, the filtration time can be extended to 25-30 seconds, while still providing effective protection against pathogens in dirty water.
