Product review (5 stars): Removes smells and improves taste.
Works very well and we feel we got our moneys worth for them! It comes as a two pack. When the 3 month changing period comes along, we are happy to replace them because they were reasonably priced and you can really taste the difference. Our tap tastes metallic and smells sulfuric, but once it goes through the filter, its great! (follow proper instructions to replace- they're in the package)
