Product review (2 stars): Dirty. I think I am going to return them.
I usually buy the 3 packs and they have a nice thick bag each filter comes in with enough room to fill with water and soak per the instructions. They are also clean. These filers were in a small, thin clear bag which did not have enough room to soak. Now besides the bag this thin has black carbon or whatever all theought the bag. There is enough on the filter itself to where I can't clean it off (pictures attached.) I won't try with soap bc I'm not drinking soap. I think I will try to return them.  :/
