Hydrapak - 42mm Filter Cap

Filter water on the go. The new 42mm filter cap on all 42mm threaded HydraPak and Flux flex bottles, turning them into filtration solutions (also compatible with Salomon and Ultimate Direction soft flasks that have a 42mm neck). At just 57 grams, our filter is one of the lightest filter options available.

• Its small size does not take up extra space when stored or slipped directly onto a water bottle.

• Prevents dust from your drink nozzle. Quickly open and close the beverage nozzle with one hand without any direct contact with dirty hands.

• The filter removes Escherichia coli bacteria, Cryptosporidium parvum cysts and Giardia Lamblia (99.9%) from approximately 1500 liters of water.
