A pool filter cartridge is an easy-to-use, cost-effective part that will keep your swimming pool clean and safe to swim in. However, this essential component can’t perform optimally when it’s clogged, which is why it’s important to recognize when you need a replacement. Here are a few common signs that indicate it’s time to swap the filter cartridge.

When to Change Your Pool Filter Cartridge

1. Visible Damage

Replace the cartridge if it shows frayed filter fabric or cracked plastic endcaps. These pieces will only become more brittle, especially when they’re exposed to swimming pool chemicals that can further their degradation. The damaged parts will warp, resulting in an ill-fitting cartridge that allows debris to pass and water to leak. Check for damage every two weeks—if there are no signs of wear, clean them with a hose before replacing them.

2. Spiking Pressure

A healthy pool should maintain a steady pounds per square inch (psi) range. Sudden spikes mean that your filter cartridge has captured too much debris and is restricting water flow. If the cartridge isn’t replaced, the accumulated pressure will strain the pump system, causing the pool’s mechanisms to burn out.

3. Old Age

The average filter lasts 2,000 hours, which is roughly one to two years. If yours is nearing this mark, replace it even if it looks great and is performing well. This component isn’t designed to be efficient beyond their life span, and you don’t want to chance accidents arising because an old filter wasn’t changed.
