How Often Should You Change Your Shower Filter Cartridge?

To keep your shower filter working effectively, regular cartridge replacement is essential. Over time, the filter media becomes saturated with chlorine, heavy metals, and sediment, reducing its ability to clean water. Most shower filters require cartridge changes every 3 to 6 months, depending on water quality and usage. Ignoring this can lead to clogged filters, reduced water pressure, or even mold buildup inside the unit. In this article, we explain how to recognize the signs of a worn-out cartridge—like changes in water smell, skin irritation, or weaker flow. We also provide tips to extend your filter’s lifespan, including pre-flushing and maintenance routines. Some filters come with indicator systems to remind you when it’s time to replace the cartridge. By keeping your filter fresh, you ensure consistently clean, skin-friendly water and maintain your filter’s performance. Don’t wait until it’s too late—stay ahead with smart maintenance tips.
