Canada's Source for Filtering Water on-the-go by Hydrapak.

Filter water on the go with the Hydrapak 42MM Water Filtration Cap. This new filter cap easily threads onto all sizes of HydraPak's 42MM threaded Seeker water storage bags and Flux flexible bottles, transforming them into filtration solutions that can be used to deliver fast and easy water treatment around camp or on the go.

Light and Compact

At only 57 grams, this filter is one of the lightest filtration options available. Its small size takes up no extra space when stored or threaded directly onto a Seeker or Flux.

Dust Cover and High-Flow Nozzle

The filter's dust cover keeps dust off your drink nozzle. Quickly open and close the drink nozzle with one hand without any direct contact with dirty hands.
