I have a unit that looks as yours but it is a Cuno Aquapure PW-RO4. I called Cuno (3M) to ask what filters I needed to order. He told me that I needed 2 carbon Pre and 1 sediment Pre (not counting the two top filters) So as I took the 3 filters out, I noticed that there was 2, instead of 1 sediment filter and only one Carbon instead of 2. The canisters also confirmed as they were labeled for 2 sediment and one carbon. Is it OK if I put in 2 carbon and 1 sediment? What would the difference be?
