After buying a years-overdue water filter replacement for under the kitchen sink, I was able to replace it myself. Luckily I double-checked instructions after putting it in: check direction of flow. Usability trap: flow direction is inverse to text direction. 😫

Water filter in place under the sink - the wrong way up. Close up of filter label showing direction of flow.
