We have these replacement parts of the filter working but not for as long as expected. It's a huge back pain to get the unit out from under the kitchen sink where we installed our system, remove all the parts, replace all the filters and then put everything back in place. I use a trash can to install the filters since unscrewing each case inevitably leaks water (due to the design of the system, this can't help but help). Sometimes a very slow leak will occur around one of the three lower main canisters and if the body cannot be tightened a bit the part will have to be unbolted and reinstalled. The whole unit is just awkward to handle, but looks nice and tidy once everything is put back together. We mainly use our system to remove nitrates from the water for our fish and for cooking.
