Hi, I have replaced the set of three filters. Do I also need to order a fourth filter? The one that sits on top of the other three? RO? Thanks


That would be the membrane. Typically the membrane only needs to be changed out every 3 to 5 years. If you have soft water running to the membrane it could last up to 7yrs. It is best to check the performance of the membrane using a TDS meter. If your unit did not come with one you can go to krystalPureh20.com and order one there.
