Replacing the water filter in your refrigerator is something you should do at least every six months or so. (You may need to do it more often based on usage and the water quality where you live.)

Those replacement filters can be might pricey, up to $50.

“We figured that over the 12-year life span of the average refrigerator, that could actually add 85 percent to the purchase price, so that is something you definitely want to keep in mind when shopping for a new refrigerator,” said Kevin Doyle, Executive Editor at Consumer Reports.
