How Often Should You Replace Your Above-Ground Pool Filter Cartridge?

Managing an above-ground pool involves several upkeep tasks to ensure it functions optimally. One critical aspect of pool maintenance is the regular replacement of filter cartridges. This task becomes especially important as it affects the clarity and safety of the water. In this article, we explore the recommended frequency for replacing above-ground pool filter cartridges, including factors that can influence the schedule.

General Recommendations

When it comes to maintaining an above-ground pool, the frequency of replacing the filter cartridge depends on several factors. If your pool is enclosed, which helps in reducing the exposure to contaminants, the frequency is often lower. Typically, we recommend replacing the filter cartridge every 3 years if you have an enclosure. For pools without enclosures, the frequency increases to every 2 years. However, regular maintenance should always be a priority to ensure the safety and longevity of your pool filter.

Regular Maintenance Checks

While the aforementioned timeline is a general guideline, it's essential to monitor the filter cartridge regularly. A good practice is to check the filter cartridge every 3 months. During these checks, it's crucial to ensure the filter’s integrity and functionality. If you notice any signs of wear, such as visible tears or deformities, it's time for a replacement.

Signs of a Need for Replacement

Subtle changes in water quality can indicate that your filter cartridge needs a closer look. One of the key indicators is a pressure increase on the filter gauge. When the pressure rises by 4 pounds per square inch (psi), it's time to clean or replace the filter. Regular cleaning can help maintain the cartridge's functionality and prolong its life.

Visual Inspection and Cleaning

During your regular maintenance checks, it's important to visually inspect the filter cartridge for any signs of damage. Check for any broken bands (which hold the pleats together), gaps or 'squishy' spots in the cartridge ends, or any issues with the connections of the cartridge caps. Additionally, inspect the filter seat for any gaps or cracks. These signs indicate potential structural weaknesses that could compromise the filter's effectiveness.

Hard Water and Mineral Build-Up

In areas with hard water or water rich in calcium, the frequency of replacement may need to be adjusted. If you experience significant mineral build-up, it's recommended to replace the filter cartridge every second season rather than following a strict yearly schedule. Hard water can erode the filter material more quickly, necessitating more frequent replacements.

Conclusion

Replacing your above-ground pool filter cartridge is a critical part of maintaining a healthy and clean pool. By following the general guidelines and performing regular maintenance checks, you can ensure that your pool remains a safe and enjoyable space. Regularly monitoring the filter pressure and conducting visual inspections will help you pinpoint any issues before they become major problems. Proper maintenance not only keeps your water clear but also extends the life of your pool filter, leading to long-term savings and a better-use experience.
