WATER FILTER SYSTEM FOR ON THE GO
With the GRAYL Geopress Purifier, you get a practical bottle water filter for travelling. Whether you’re camping, on a hiking trip, canoeing or travelling, you can use questionable water sources and surface water to produce drinking water.

TURN DIRTY WATER INTO DRINKING WATER EASILY
Pour the dirty water into the “outer” bottle. Then insert the “inner” bottle, with the filter cartridge sitting at its base. Push the filter cartridge down through the dirty water. Suspended particles, chemicals and pathogens remain in the filter membrane, and the inner bottle fills with clean water.

WITH SIMPLEVENT DRINK CAP
The SimpleVent Drink Cap drinking lid serves multiple functions. The cap vents and cleans the air, protects against cross-contamination, dirt and contaminants, and allows one-handed liquid dispensing through a quickly flowing drinking spout.

UP TO 250 LITERS CAN BE FILTERED
A total of up to 250 litres of water can be filtered (depending on water quality). With daily use once per day, the service life is about 1 year; with less frequent use, however, it should be replaced after no more than 3 years.
