Product review (5 stars): So far so good.
I swapped out my factory filter for this one after doing a little research.  Since these are made in the USA and new (not recycled) I tried one.  After 3 month things are good.  The taste is great since we have a lot of chlorine taste in our tap water and these remove it.  I will buy again since they are less than half the price if bought in more than single units.  That way I will replace them when the fridge tells me to rather than try to squeeze more life out of a more expensive one.
