Tim Leid wrote a question about MSR Sweetwater Filter Cartridge on March 21, 2011
I have just purchased a replacement cartrige for my purifier. My old cartrige has the "in" port nipple on the cartrige but the new cartrige has none. Does part of the old cartrige have to be removed and placed into the new cartige, and if so, how does this come off? I have about a 25 year system.
