Product review (4 stars): Good filter for the cost
Great filter for the price.  I think the water tastes good,  but our tap water is also not bad at all.  I, admittedly, replace this every month.  I love the "flavor" of good water so I don't mind the cost.  I have let it go longer than that, and feel the good flavor from this filter drastically reduces after a month.  I can buy 4 of these for the price of OEM, which I'd also replace after a month or 2, so I am still satisfied.
