May be too delicate for the outdoors

I've used it once or twice and have initial impressions

I used this filter on a short two-day hike using the filter twice on the trip. When I got home I cleaned it before storing it and discovered there is a pin hole leak in the membrane. So, despite not laying it on the ground, not letting it come in contact with any abrasive surfaces and storing it in its own bag, it still got a puncture. The cherry on top is my boyfriend warned me and teased me for buying this filter because he didn't think it would hold up outside. I will say the filter does work very well, is easy to use and clean, and had good water flow. It's just too bad from my experience that the membrane is not durable enough for any real use outdoors. So, be careful handling if you choose this filter. I hope Katadyn makes some improvements because I did enjoy it while it lasted (2 days).

Great Product

I've used it several times

This is the water filtration to have. So much easier than the squeeze filtration systems. I was the only member of the last backpacking trip that had this Katadyn, other guys had the squeeze bags. We ended up using the squeeze bags as storage and just hung the katadyn on a tree and refilled it when it was complete. Well worth the extra dollars.

Thanks for your feedback John!!

Great product, poor packaging

I've used it several times

The only reason this product is dinged is because Katadyn used a giant box for this product, which could easily been packaged in a much smaller container. Great product. Does the job. Packs down to a very small and manageable size. Don't forget to pack a strap to adjust the height. I found it best to adjust the filter tip to the height of the jug or water bottle being filled.


does the membrane need to be replaced from time to time? if it does, how often? thx


Has anyone tried using Nuun or other electrolyte replacement products in the bladder? Does it mess with the filter at all?


Just want to know how large the fill opening is?
