I can't address the kind of filter but I an say to mount it where it is easy to change the filter, not where it is easy to mount. Some inconvenience during installation will pay off when it comes time to change the filters. I've mounted a couple in the basement at waist high just to make it easy to change the filters. A lot of the time you will spill some water changing them too. The easier it is to change the filter the more likely you are to change it when you should.
