How to Clean a Cartridge Pool Filter

Proper maintenance of your pool’s cartridge filter is essential to keep your water clean and your system running efficiently. In Nashville, where warm weather and heavy pool usage are common, maintaining your filter is even more critical to ensuring your pool stays pristine. Over time, debris and oils can clog the filter, reducing its effectiveness. Follow these steps to clean your cartridge pool filter and keep your pool sparkling in Music City.

What You'll Need:

• Garden hose with a spray nozzle

• Filter cleaning solution (optional, for stubborn buildup)

• Large bucket or trash can (if soaking the filter)

• Rubber gloves

Step 1: Turn Off the Pool Pump

Before starting, ensure the pool pump is turned off. This prevents water from flowing through the system while you remove the filter.

Step 2: Remove the Cartridge Filter

Open the filter housing by loosening the clamps or screws, depending on your system. Carefully remove the cartridge filter and set it aside. Take note of how the filter is positioned for easy reinstallation.

Step 3: Rinse Off Loose Debris

Use a garden hose with a spray nozzle to rinse off dirt, leaves, and other debris from the filter. Start at the top and work your way down, cleaning between the pleats. Avoid using a pressure washer, as it may damage the filter.

Step 4: Soak the Filter (Optional)

For heavily soiled filters, soak the cartridge in a cleaning solution. Fill a large bucket or trash can with water and add a filter cleaning solution according to the manufacturer’s instructions. Submerge the filter and let it soak for at least 8 hours or overnight to remove oils and grease.

Step 5: Rinse Thoroughly

After soaking, rinse the filter thoroughly with the garden hose to remove any remaining cleaning solution. Ensure all debris and residue are washed out from the pleats.

Step 6: Inspect the Filter

Check the filter for signs of wear or damage, such as tears in the pleats or a collapsed structure. If the filter is damaged, it’s time to replace it.

Step 7: Reinstall the Cartridge Filter

Place the cleaned or new filter back into the housing. Ensure it is seated correctly and securely. Close the filter housing and tighten the clamps or screws.

Step 8: Restart the Pool System

Turn the pool pump back on and check for any leaks around the filter housing. Monitor the system to ensure it is running smoothly.

How Often Should You Clean the Cartridge Filter?

In Nashville, where pools are often in use for extended seasons, you should clean your cartridge filter every 4-6 weeks during the swimming season. If your pool sees heavy use or if you experience frequent algae blooms, you may need to clean it more often.

Additional Tips:

• Always follow the manufacturer’s guidelines for cleaning and maintenance.

• Avoid using harsh chemicals or abrasive tools on the filter.

• Replace the cartridge filter every 1-2 years, depending on usage and condition.
