Run fast, filter faster.

The UltraFlask+ Filter Cap threads seamless onto all of HydraPak’s 42mm running flasks and handhelds for a lightweight, straightforward filtration solution.

Featuring a traditional bite valve and cap design, runners can drink freshly filtered water directly through the high-flow Blaster valve.

  • Light And Compact: Minimal design and lightweight materials make this filter the ideal choice for runners. It takes up no extra space when stored or threaded directly onto a flask.

  • High Flow: Easy to drink bite valve auto-seals after each sip, eliminating annoying drips.

  • 42mm Thread Compatible: Easily thread the filter onto some of the most popular running softflasks, flexible bottles and water storage containers.

  • Included Backflush Adapter: Plugs into filter valve and threads onto a HydraPak Stow or bottle of clean water for backflushing the filter to restore its flow rate.

  • Fast & Safe Filtration: The integrated filter removes Escherichia coli bacteria, Cryptosporidium parvum cysts, and Giardia Lamblia from approximately 1,500 liters of water at a rate of >1L per minute.*
