42mm Filter Cap
Fresh and safe water, always and everywhere
Filter your water on the go. The new Hydrapak 42mm Filter Cap threads seamlessly onto all sizes of Hydrapak’s 42mm threaded Seeker water storage bags and Flux flexible bottles morphing them into filtration solutions. The end result being lightweight filtration kits that can either be used to squeeze filtered potable water into other camp bottles and containers or to drink freshly filtered water. Both deliver fast and easy water treatment around camp or on the go.
Light and compact
At only 57 grams, our filter is one of the lightest filter 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
Keeps dust off your drink nozzle. Quickly opens and closes the drink nozzle with one hand without any direct contact with dirty hands.
