You mean the filtration-type pitchers? I imagine it might get clogged quickly but have no experience with these.

Yes, exactly what I mean, the only reason I put the effort of making an account and posting a question is because I cannot find an answer elsewhere.

Why would you want to? Do they not sell coffee filters where you are? It is an extremely simple process, no need to try bigger and better.

I would be concerned that the active carbon will hold more then what you want it to. I am aware that they do not filter out everything but i am not sure if it filters out ions from the water as you are essentially asking "can i run a dissolved salt through an active carbon filter?"
I am able to find information showing that common table salt should get through. It is a very hard question to answer and i would imagine it depends on the size and charge of the compound attempting to pass though. So your brita filter will not filter out salt water enough to drink, it will not filter out all dissolved ions but it will probably filter out some.
Try looking it up based on the full theory of what you are doing which is: "can i run a dissolved salt through an active carbon filter?"

I read a tek once for doing that for AC&C. Most people know that a cold water extraction still leaves behind the caffeine in AC&C, and you're mostly counting on codeine's solubility in cold water and using the least amount of water possible to maximize the amount of codeine extracted while minimizing how much "space" is left over for the caffeine. The caffeine that gets through can still make you feel like shit though, and so I saw a tek where you take the post-CWE caffeine/codeine water and run it through a Brita-type filter, and the activated charcoal will remove the caffeine but leave the codeine.
I never actually tried this to see if it works, but a quick google search for "caffeine brita filter" shows a ton of threads here and elsewhere where people have mentioned that they do it. YMMV, can't hurt, but might affect your codeine yields.
Other than that though, there's no reason to do this versus just using a coffee filter. Just pre-wet the filter, and don't squeeze the shit left in the filter afterward unless you then let that water run through another filter.
