Product review (2 stars): All my fault!
These "Premium Water Filters" fit perfect and are of the highest quality. They do exactly what they say they will do. The problem is that I did not realize what I was purchasing. I guess I needed the company to be clearer in the product description. The original filter that comes with the refrigerator  filters out chlorine, but it also filters out heavy metals. The replacement filters are quite pricey. Fifty dollars for a six month filter! Well, I shopped around and found this three pack for about the same price. WOW! what a deal, except for the fact that these filters do not filter heavy metals, only chlorine. I did not know before purchasing these filters, but even though the filters look alike all filters are not equal in what they filter. If you only need to filter chlorine then these are 5 star filters, if you need more, like heavy metals, then look for a different product.
