Hi Dave, We must have different ICE filters! I don't have mine at hand to measure, but they're not anywhere near the size of a K2! I'm on a six-month RV trip away from home, so I can't measure them, but the entire box I have them -all- stored in is smaller than a K2. They only weigh ounces per each. 73!
