Can I count replacing my 4396510 refrigerator filter as having a productive day? As I reflect on my day and all of its accomplishments the only thing that I could cross off my to do list was “replace water filter on fridge”. Granted this item has been on my to do list for quite some time and has needed to be taken care of for the water safety of my family, but I still can’t believe that is all I have done today. So, I am trying to do my best to think of changing out the filter as a much more than a menial task and think of it as a lifesaving measure I am taking to protect my family.
