All in all I'm happy with the filter, however, the last time I needed to purchase one, they were out-of-stock everywhere with no notation on the website as to when they would be available again. This makes me nervous as to what might happen in the future if this filter becomes unavailable for good. Now I know to always have a back-up ready. The new filter I recently purchased looks different from what is pictured on the website as well as what I previously purchased. It looks as if the filter components don't quite fill the container, which makes me wonder if all the water is actually processing through the different filters.
