Pentair OMNIFilter QuickConnect Composite & Carbon Filter Twin Pack, Includes CB-12M Carbon Filter and CF-12M Composite Filter, for Use in OMNIFilter T600RO 3-Stage Tankless RO System

I have a Pentair OMNIFilter system for my drinking water that I purchased a few years back and it stopped working recently with a red light to change the filters. So I purchased a 2 pack from Amazon which last about a year. When they arrived installation was very easy and within minutes my water filter system was up and running again.

Easy to replace if you pay attention. The filters come with a plastic cap to protect the inlet and outlet spickets. Don't do what I did with the first filter I replaced. There are two small rubber insert caps/plugs in each of the new filter's spickets; they need to be removed. Remember to remove them before you insert the new filters into the filter compartments. I failed to do this, and it took me about 20 minutes to get one of the plugs out of the filter housing.I'd suggest you download the instructions from the Pentair website before you remove and replace the filters. The instructions are simple, but you should turn the water supply off and drain the filter before removing and replacing the cartridges. They are a simple push and turn 90 degrees to remove and reverse the procedure to install the new cartridges.
