How to Clean Your Pool Filter Cartridge

Pools provide a great way to cool off during the hot summer months. But, maintaining a pool is also a critical part of owning a pool. One of the most crucial aspects of keeping your pool sparkling clean is ensuring that your pool filter cartridges remain free from dirt and debris. If your pool filter cartridge isn't regularly maintained, not only can it lead to an unsightly and unclean pool, but it can also damage the overall pool equipment. So, without further ado, let's dig into how you can effectively clean your pool filter cartridge.

Why is Cleaning Your Pool Filter Cartridges Important?

If you own a pool, you already know that sanitizing the pool water is an essential task. The pool filter cartridge bears the responsibility of eliminating dirt, debris, dead bugs, and leaves from the water. As the filter gets old, dirt and debris accumulate on it, and the filter becomes less efficient. As a result, the pool water remains cloudy, and it can damage the pool equipment by creating a blockage in the water pipes. You need to clean the pool filter cartridge at least bi-weekly to maintain a healthy and crystal-clear pool.

Steps To Clean Your Pool Filter Cartridge

Cleaning a pool filter cartridge isn't rocket science, and with a few tools and some professional guidance, you can quickly get it done in under an hour. Here are the steps you'll need to follow to get your filter cartridge clean and working like new:

Step 1: Prepare the necessary tools and materials.

To clean your pool filter cartridges, you'll need a few essential tools and materials, including rubber gloves, a garden hose, a large plastic bucket, a cartridge filter cleaner, and cartridge filter degreaser.

Step 2: Turn off the pool's filtration system.

Before cleaning the pool filter cartridge, turn off the pool's filtration system to avoid injury, and ensure it isn't operating.

Step 3: Remove the pool filter cartridge.

Remove the pool filter cartridge from its housing and place it onto a clear work surface, preferably a flat surface like a workbench.

Step 4: Inspect the pool filter cartridge for dirt and debris

Before cleaning your pool filter cartridge, inspect it for its condition. If it's beyond repair, you may need to replace it. If only dirt and debris are visible, you can clean the pool filter cartridge with a dedicated cartridge filter cleaner.

Step 5: Soak the pool filter cartridge in a cartridge filter cleaner

Soak the pool filter cartridge in a bucket of water mixed with cartridge filter cleaner. Leave it to soak for a few hours or until it looks clean.

Step 6: Rinse the pool filter cartridge

Use a high-pressure hose to rinse the cartridge in both directions to remove all the remaining dirt and debris.

Step 7: Apply cartridge filter degreaser

After rinsing the cartridge, apply cartridge filter degreaser to remove any grease or oils that may have accumulated. Allow the degreaser to soak in for the recommended time.

Step 8: Rinse the cartridge filter for the last time

Using the high-pressure hose, rinse the cartridge from top to bottom.

Step 9: Reinstall the pool filter cartridge

When the cartridge filter is clean and free from dirt and debris, reinstall it, ensuring that it is correctly positioned.


Undoubtedly, cleaning your pool filter cartridge is an essential process for maintaining a clean and healthy pool. Ensure that you clean it at least twice a month to prevent dirt and debris from accumulating on it.
