Product review (5 stars): I like to save money
Not all filters are the same.  I like to save money, but the GE filter meets NSF 42 and 53 standards.  Cheaper ones only meet the 42 standards for taste and chlorine.  The 53 standard mean that the filter will remove toxic metals and organics.  If you are unsure about the quaity of your water, the GE filter or others that meet the NSF 53 standard should deliver higher quality water.
