We recently replaced our refrigerator water filter for the first time. We figured it was time, since we've lived in our house for two years and hadn't replaced it yet. Not to mention we got our annual water report and it wasn't good news for our local drinking water. So fresh filter it was! The best part was the misprint in the instructions. See number 6 below.
We call out fridge the "nito" fridge now, and giggle every time.
