Filter water on the go. The new 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 from a Seeker, Flux, UltraFlask or SkyFlask. Both deliver fast and easy water treatment around camp or on the go. 

Feature:

• HIGH FLOW RATE: Access potable water anywhere. Filters approximately 1,500 liters of fresh water at a rate of >1 L per minute.
• SAFE: Effectively removes common waterborne bacteria (99.9999%), and parasitic cysts (99.999%) per EPA Guide Standards and microplastics (99.999%) per NSF 42 greater than or equal to 3.0 microns in size.
• EASY TO USE: The high flow drink nozzle is easy to open and lock with one hand, and is equipped with a dust cover that keeps your valve clean and protected from the elements.
• COMPATIBLE: Perfect for trailrunning, cycling or backcountry water filtration. Works with all 42mm opening HydraPak products including running flasks, Seekers and Flux bottles.
• LIGHT & 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 our Seeker or Flux.
