This filter cartridge is 1/4" shorter than advertised. The spec lists a length of 9 3/4 inches. (which is listed in the description of this cartridge) but it is only 9 1/2 inches long. It doesn't seal because it's too short. You may not notice this problem if your filter housing is not transparent. I saw the filter pop up leaving a 1/4 inch gap at the bottom. I found this odd because it's a Campbell system and it's supposed to be a Campbell cartridge.
