How Long Does a Cartridge Pool Filter Last?

Whether you are a new pool owner or have an old pool in your backyard, you must attempt to keep your cartridge pool filter in good condition. Cartridge pool filters are much easier to use and demand low maintenance compared to other pool filters. But even with the best maintenance methods, these filters will last you for a limited period. 

How long does a cartridge pool filter last, and what factors can increase or decrease this lifespan? Let's discuss it!

How Long Does A Cartridge Pool Filter Last?

On average, a cartridge pool filter will last you around 1-3 years before they need replacement. However, this time period may vary due to a number of underlying factors. Some common signs will tell you whether your pool filter cartridge needs changing. 

You may notice excessive wear and tear on the filter cartridge, flattened pleats, broken bands, or poor water filtration quality. If your filter continues to filter water poorly after cleaning, it may be time to have it replaced. 

Factors Affecting Cartridge Pool Filter Lifespan

The lifespan of a cartridge filter will rely on several factors, including: 

1. Usage

The number of years your pool cartridge filter lasts will depend on the pool size and how often it runs in your household. Most filter cartridges will indicate the predicted lifespan; if this date passes, it may be best to replace the filter. Pool filters that pump high amounts of water daily will tend to wear away more quickly and so will need quicker replacement. 

2. Water Chemistry

Poor water chemistry with improper chemical balance can lead to the growth of algae. This alga can put additional strain on your swimming pool cartridge filter, further reducing its lifespan. Some areas tend to naturally have poor water quality, so you may need to replace the water filter cartridges more regularly. 

What you can do is use a filter saver or skimmer such as these to scrape away as many particles of debris as possible before they enter the cartridge filter. Such high-quality skimmers can go a long way in filtering most of the heavier debris and other waterborne particles. 

3. Maintenance

The total lifespan of your pool filter cartridge will depend greatly on how well you clean and maintain it. Never let excessive dirt or debris build around your cartridge, and give it a thorough clean at least once every 3 months. 

You should also inspect the pressure levels of your filter from time to time. If the pressure rises more than 8-10 pounds than the normal level, your cartridge needs to be cleaned out. 

4. Quality 

Finally, the lifespan of your cartridge pool filter will depend on the quality of the filters you purchase. A normal cartridge pool filter lasts 1-3 years, but high-quality filters such as the Poolking Cartridge Filters can last up to 5 years or more with proper care and maintenance. 

Final Thoughts

The lifespan of a cartridge pool filter depends greatly on a number of factors including the water chemistry, level of maintenance, and usage frequency. On average, your pool filter will last up to 5 years, but with property care and maintenance, you can ensure your cartridge pool filter lasts as long as possible.
