The cartridge pool filter is a type of pool filter that uses a cloth-like material to filter water in your pool. The cartridge filter is an important component of your swimming pool's filtration system.

Signs You Need To Replace Your Pool Cartridge Filter
1. Poor Water Quality
If you notice your water is staying cloudy or green despite using Swimming Pool Chlorinators, sanitizers, and filtration, it may be a sign your filter cartridge needs replacement. You should still try cleaning out the cartridge first to see if any dirt or debris clogged in the cartridge is hindering its efficiency. If this doesn’t offer any substantial results, you may need to replace it.
2. High PSI Reading
If you notice a spike in the pressure reading on your pool cartridge filter, it may be a sign of a dirty or clogged cartridge. The high PSI reading may also result from a dirty cartridge, in which case you should give it a cleaning session. If the treated cartridge still shows high PSI readings, it must be replaced.
3. Cracked End Caps
The end caps on your cartridges hold the cloth-like pleats in place, sort of like bookends. Over time, the effects of water chemicals and pressure can lead to the end caps cracking. It needs to be replaced if you notice any chipping or cracking on the carriage end caps. If pieces of the end cap chip off, they may pass through to the filter system and cause damage to your pool.
4. Signs of Wear and Tear
Next, you need to look for general wear and tear signs on your pool cartridge filter. If the filters look frayed and tattered, they have passed their life expectancy and can no longer effectively filter pool water for you. The cartridge filter may also have noticeable holes or tears due to the effects of debris. Cleaning such filter cartridges won't be enough; they must be replaced immediately.
5. Broken Cartridge Bands
You will notice several bands running around the cartridge; these are added to prevent the pleats from losing their shape due to the turbulence caused during water filtration. These bands may start breaking down at some point. The more breakage your bands bear, the less effective they are at keeping your cartridge pool filter pleats in shape. If you notice significant breakage, you should have the cartridge replaced.
6. Deformed Filter Pleats
New filters tend to have consistently placed pleats; as they filter dirt, debris, and other contaminants, they will start to flatten and lose their shape over time. Flattened filter pleats can no longer filter water the same way and should be replaced.
Your filter cartridge may appear clean, but even the best cartridges need to be replaced at some point. On average, you should replace your pool filter cartridge every 1-2 years. If you notice any of the signs mentioned above, you need to replace the filter as soon as possible for clean, clear, and healthy swimming.
