We just wanted to replace all the filters and membranes in our Hydrotech reverse osmosis system. It was a complete kit which made the swap really easy. The pre-filter was a little taller than the original filter (or so it looked), but that's not a problem for our water supply. Reverse osmosis membrane and activated carbon filter before and after cleaning also work great. 5 Stars.
