Filter water on the go with the new HydraPak 42mm Filter Cap. It threads seamlessly onto all sizes of HydraPak’s 42mm threaded Seeker water storage bags morphing them into backcountry filtration solutions. The result is a lightweight filtration kit that can either squeeze filter potable water into other camp bottles and containers or drink freshly filtered water straight from your Seeker reservoir. The 42mm Filter Cap uses a 0.2-micron Hollow fiber filter providing a 1 liter per minute flow rate and effectively removes protozoa, cysts, and bacteria for up to approximately 1500L of filtered water. The 42mm Filter Cap is the perfect solution for fast and easy water treatment around camp or on the go.

"Between the flow rate and lifespan of this filter and the avaliablity to carry 3L of water, plus more with the other Hydrapak bags has been huge in my hydration system. Great product."
"I just used this last week and it performed great! It is my favorite way to filter water. If you're filtering running water, if it's lake water, or water that is a mud puddle, then I would take another approach, for this filter will clog quickly."
"The filter cap and system are about as good as it gets. Super easy and a fast flow rate. The cap and bottle pack up small to stay out of the way. Good bye Sawyer!"
"Super light weight and seems very simple to use! Will put it to the test in a few weeks!"
"Works well. Filters at a high rate. Easy to open and close. Stays closed."
