We have used this for many years and love it. They help soften water and remove sediment, allowing you to actually wash your face with clean water. The case will melt a bit over time so opening it at the time of changing the filter can be a problem. A stainless steel case is better as plastic cases will crack over time. However, Revane's supplies appear to be fickle. We ordered 2 packs of two with a total of 4 filters. But we have 3 filters and 1 plastic case. We kept it anyway because it was a warehouse deal, so it was already discounted. Although I would still buy them again.
