What's the recommended filter replacement schedule for my PENTAIR QL3B water filter?

[Kent]

To keep your PENTAIR QL3B water filtration system running smoothly, you should replace the filter cartridge based on the following guidelines: Firstly, aim to change the filter every six months. Secondly, replace the cartridge if you notice a drop in water pressure or flow, which signifies a buildup of sediment. Finally, always replace the filter at least once a year, even if you haven't experienced any performance issues. Regularly replacing the filter cartridge is key to ensuring your system performs optimally and provides clean water. For replacement cartridges and parts, contact your local Pentair Everpure dealer.
