Product review (4 stars): Great fit, Good Price! But do your research.....
Purchased this filter because I didn't want to pay $49 for one filter.  This filter fits perfectly.  Thought all filters had to be the same  as long as they fit and didn't leak. Not so!  This filter is only rated NSF 42 which filters mainly for taste and odor (chlorine, chloramines, etc.). If you want a filter that provides more health benefits (by getting rid of more chemicals, heavy metals, nitrates, etc.), then go for a filter with a NSF 53 rating. The product is as described, but do your research and understand what you are purchasing. I did my research a little too late.
