Product review (2 stars): Doesn't reduce contaminants related to Health
Like another reviewer had mentioned, this is NOT a apples to apples replacement for the more expensive Kenmore filter (9690) in terms of the NSF/ANSI standards.  For example I have the Kenmore 9690 filter performance data sheet next to me.  It claims to meet NSF/ANSI Standard 42 AND 53.  The Refresh Model R-9690 data sheet says it meets NSF/ANSI Standard 42 only.  NSF/ANSI Standard 42 = Aesthetic Effects
NSF/ANSI Standard 53 = Health Effects.  Ex. Standard 42 (as mentioned in the Refresh data sheet addresses "Chlorine Taste & Odor" whereas the Kenmore filter reduces - Chlorine Taste and Odor, Nominal Particulate Class, Asbestos, Atrazine, Benzene, Carbofuran, Lindane, P-Dichlorobenzene, Toxaphene, 2,4-D, Lead pH@6.5, Lead pH@8.5, Mercury @pH 6.5, Mercury @pH 8.5, Cyst (Cryptosporidium parvum oocysts).

There's quite a big difference between the filters as you can see.  I'll be returning this one and stick with the original Kenmore; there's a reason it's more expensive.
