Product review (5 stars): These genuine Kenmore meet NSF 53 (for health) as well as 42 (taste/odor). Those cheap filters do NOTHING for your health!
Yes, these genuine Kenmore filters are more expensive than the cheaper "compatible" filters being sold but there is a reason for that. These genuine Kenmore filters meet the requirements for BOTH NSF/ANSI Standard 42  AESTHETIC Effects AND NSF/ANSI Standard 53  HEALTH EFFECTS. The cheaper filters meet the standard 42 to make the water smell and taste better but DO NOTHING to remove anything harmful to your health (covered by Standard 53) from your water. If your water is already very good and has nothing harmful in it this may not be of concern to you and you can go ahead and buy the cheaper filters. These filters DO meet Standard 53 which covers the removal of things like: microbiological, filterable cysts, disinfection byproducts, pesticides, herbicides, insecticides, heavy metals (arsenic, cadmium, chromium, copper, lead, mercury and selenium), fluoride, nitrate, nitrite, chloroform and more. Take your pick based on how good your tap water is or on how much you really trust that tap water!
