GRAYL GeoPress Replacement Filter & Purifier Cartridge (Black)

The replacement filter is a more expensive than some full filter systems. However, it removes almost everything including viruses & bacteria, filters 250 liters of water & has a 10 yr shelf life, so do the math.

These cartridges do a great job removing bad tastes and impurities. Used one for tap water all over Thailand and never got sick (except when I bought an iced coffee on the street in Bangkok and forgot about the ice in it).

Had to get this replacement filter because I left my bottle full of water ,and even after washing/rinsing the bottle my water had a funny taste. After replacing the filter the water tastes fine. Dont be like me and leave water sitting in your bottle, or youll need to get a replacement filter too!
