Start by selecting your Pentair reverse osmosis system above. You'll be taken to a page that provides manuals or instructions for your specific model. General RO filter replacement instructions are available here.

Start by clicking on the photo of your Pentair reverse osmosis model above. From there, you can add the needed filters to your cart. In some cases, you can save time by ordering all of the needed filters in one "filter kit" (not available for all models). Keep in mind that the RO membrane usually only needs to be replaced every two years, while the sediment and carbon filters are replaced every 6-12 months depending on water usage and water quality.

You can check if your Pentair RO system is functioning properly by monitoring the water flow, inspecting for leaks or unusual noises, and testing the water quality for any unusual taste, odor, or appearance. Additionally, regular filter replacement and maintenance ensure optimal performance. If you notice any significant deviations from normal operation, it's advisable to consult the system's manual or contact Pentair's customer support for guidance. If you are having issues with your RO system, you may want to consult our RO Troubleshooting Guide.

The reverse osmosis filtration process ensures high-quality, great-tasting drinking water.
