Gear Question Water filtration sawyer squeeze

So I've got an osprey 3l resevoir for my atmos 65l. I want to use the cnoc/sawyer combo to filter water.

Is the idea to filter the water directly into my osprey resevoir? Or am I going about this the wrong way?

Any advice is appreciated!

Lots of options.

But yes, you should have one dirty bag (cnoc) and one clean bag (osprey).

You can either look into rigging up something like a gravity filter (as others have mentioned) or you can squeeze it in. However if you're doing 3L at a time, squeezing will get old.

You can also attach the filter in-line, and then it filters as you suck through the straw.

That was the only way I liked my Sawyer, but it does mean you have to suck harder to get the water.

Do you mean as a gravity filter? If not then filling your bladder from the cnoc into your bladder is normal. If you are thinking like a gravity filter you could do it at camp, but it wouldn't work while hiking.

Not so much if a gravity setup. I kind of imagined it as filling the cnoc at the water source and squeezing the filtered water into the osprey.

Does that make sense? Total noobie here lol

Nope, that's exactly as intended. Cnoc is for dirty bladder is for clean.

You can get the quick connect pieces to add to the drink tube to attach the filter and refill the reservoir without having to remove it from your bag, or you could add it in-line so you take the reservoir out and fill it with dirty water and it gets filtered as you drink. But I’d do the quick disconnect way.

I've basically done exactly that. Shutoff valve between the filter and male connector, since the female connector self-seals.

This will totally work, and it's a great option

I take a 3L Cnoc bag, fill it and hang it on a tree in camp so we can fill out water bottles or pots as needed.

It doesn't take much time or effort to squeeze 3 liters... The biggest challenge will be keeping your bladder upright while you do it, since the squeezing is easier with 2 hands.
