How often should filter cartridges be replaced?
Hi, Thank you for Contacting PoolZoom. That is a fantastic question. Industry standards are between 1-3 years. However, the life of filter cartridges will depend on multiple factors: water pressure, chemicals, amount of debris, ect. This causes the cartridge material to wear at different rates for different folks. When you begin seeing signs of fraying or tiny tears in the fabric it is time to change your cartridge. Your cartridges may appear kinda “furry” on the surface. It is also time to change if any of the folds of your cartridges have become deformed or flattened, or you notice any bands holding the cartridge together are broken. Thank you! PoolZoom
