As set only recommended as compared to the individual prices which set would come much more expensive. Had five stars awarded but unfortunately I had in the package insert of the water filter then read this should come for kidney patients people have only limited use because of water filter generally increases the levels of potassium. This applies to dialysis patients and people with impaired renal function, they should be advised by their doctor about the use of such filters. I find such a notice would have to be found in the product description and not only in the package insert of the filter then the customer already could decide whether to buy those products or not.
