Awesome flow rate, easy use

I love this filter! I use it in conjuction with a cnoc 42mm bag. That combination works great for me. I don't use the befree bags. In any case, this filter works great! It does lose some flow rate as it gets dirty (like all filters) but in my humble opinion; this has the best overall flow rate. I think my first one lasted about 1800 miles (on a thru hike) before I swapped it out. But 700 miles of that was the desert and I was filtering a lot and using it several times a day. I replaced it because even with back flushing, I couldn't get the flow rate back. only downside (in my opinion) to these filters is the price, and they are much more limited to what bottle, or bags they'll fit onto... At 25 dollars each, it's definitely not cheap.. and in theory you won't get near the life out of what you might get from something like the regular sawyer squeeze.. the befree will get you roughly a 1000 liters. I wait until I can find them on sale and just stock up..cheapest I've ever found these replacement filters was 17 dollars. Two should all you really need for a thru hike, if you take care of it properly. Don't let it freeze or bye bye! And backflush when you can. I also highly recommend getting something like a cnoc bag to use with it.. the standard befree bag is ok, however, it can be much slower collecting at smaller water sources.. the befree bag also isn't nearly as durable as something like the cnoc vecto bags..

Great replacement

This is a great replacement for the Karadyn BeFree filters. I have a flask that I bring on longer hikes near water so I do not have to worry about lugging a bunch of water around or getting sick of if I drink from a stream.

Do you know if this will attached to the Platypus bottles?


Can this be paired with the CNOC water bags?


Similiar question to the previous one. I've read a couple reviews that said that this fits the bottles that came with the reviewer's running vest (which makes sense since many of the soft flasks that come with running vests are also made by Hydrapak). Can anyone confirm whether or not this will fit the flasks that come with the Ultimate Direction Ultra 5.0 vest? Or any of the UD Signature series 5.0 vests (I am guessing they use the same soft flask)?


Does this fit the Salomon (Hydrapak) 500ml softflasks? Thanks!

Thanks for the inquiry, Joe! No this element will not be compatible with the Salomon soft flasks but it is compatible with Hydrapak's Seeker and Stash series of collabsible watter bottles.
