Product review (3 stars): filters water, doesn't last very long
We have this on our Samsung refrigerator with water supplied via well. We already have a house filter to remove sediment but still after about 2 months this filter begins to really restrict the flow of water coming out of the fridge. For comparison I do not need to clean the toilet tanks of excess (or any) sediment, so I am not sure why these don't last as long as the 6 months they are advertised to.
My wife does drink a lot of water so it may be that we drink more water than the average family. In any case, the water does taste better than what is coming out of the sink. I took off two stars because it only lasts 60 days vs. 180, your experience may be completely different.
