Product review (5 stars): Keep a spare on hand
Some folks with city water envy their country cousins because they think that their ground water must taste like the some clear gushing mountain stream fresh off a glacier. In our area the aquifer water is overflowing with not-so-tasty minerals that leave a rusty residue on everything including clogging the washing machine cold water intake filter. The point is city or country you are better off filtering your drinking water.  This Frigidaire filter is literally a snap to install.  It is supposed to filter up to 200 gallons before the change-filter indicator goes off on the front of the fridge, but I've found that individual mileage may vary. The filter does it's job - you can easily tell the difference between the unfiltered tap water and the filtered water out of the fridge when the well water is "running cloudy."  Even if it doesn't seem like it should be time to replace it you will know when the water coming out the dispenser on the front of the fridge begins running very slowly.  I've used several of these - sometimes they last one or two months and sometimes they go much longer, just depending on the quality of the water being filtered.
