How to Clean a Pool Filter Cartridge


A clean pool filter cartridge is essential for maintaining clear and healthy water in your swimming pool. If your filter is clogged or dirty, it reduces circulation and can allow unwanted debris and bacteria to thrive. Cleaning your pool filter regularly not only extends its lifespan but also ensures your pool stays a refreshing retreat.

Whether you're a homeowner in Orlando, FL, or somewhere else enjoying year-round swimming, proper pool maintenance is crucial. This step-by-step guide will walk you through how to clean your cartridge filter, ensuring peak performance. Plus, if cleaning feels too overwhelming, we'll share how professional pool services in Orlando, FL, like Pure & Simple Poolcare, can keep your pool in pristine shape.
 

Why Cleaning Your Pool Filter Matters

Your pool filter cartridge works tirelessly to trap dirt, oils, insects, and other particles, leaving your pool's water clear and safe. But over time, grime builds up, reducing the filter's efficiency. Here’s why cleaning your pool filter regularly is essential:

  • Improved water clarity: A clean filter ensures dirt and debris are effectively removed, keeping water sparkling.
  • Enhanced efficiency: Filters clogged with debris force your pump to work harder, increasing energy costs and wear.
  • Extended cartridge life: Regular maintenance can prolong the lifespan of your filter, saving you from costly replacements.
  • Healthy swimming environment: A clean filter prevents algae and bacteria from spreading in your pool.

Now that you understand the importance, let's discuss how to clean your pool filter cartridge step by step.
 

How Often Should You Clean Your Pool Filter?

Generally, it's advisable to clean your filter cartridge every 4–6 weeks. However, this may vary depending on usage and weather. For example, pools used daily or located in areas with heavy debris often require more frequent cleanings.

Also, keep an eye on your pool’s pressure gauge. If the pressure rises 8–10 PSI above the standard reading, it’s a sign your filter needs cleaning.
 

How to Clean Your Pool Filter Cartridge

Follow these five steps to clean your pool filter efficiently and effectively.

Step 1. Turn Off Your Pool Pump

Before cleaning the filter cartridge, always turn off the pool pump to prevent accidents or damage. You should also release any pressure built up in the filter system by opening the air relief valve.

Step 2. Remove the Cartridge from the Filter Housing

Locate the filter housing, unscrew the lid or clamps, and carefully remove the filter cartridge. Take note of how it's installed so you can easily put it back together later.

Step 3. Rinse Off Loose Debris

Using a hose with a spray nozzle, gently rinse the cartridge to remove surface dirt and particles. Hold the hose at an angle and run water between the pleats to dislodge debris completely. Avoid using a high-pressure washer, as it can damage the pleats.

Step 4. Deep Clean with a Filter Cleaner

For stubborn oils, grease, or calcium deposits, a deep cleaning is necessary. Follow these steps:

  • Prepare cleaning solution: Mix a commercial pool filter cleaner with water as directed on the label. Alternatively, use a solution of one part vinegar to three parts water for a DIY approach.
  • Soak the cartridge: Submerge the filter in the solution for 6–8 hours (or overnight) to break down grime.
  • Rinse thoroughly: After soaking, rinse the cartridge with water to remove all cleaning residue.

Step 5. Inspect the Cartridge

Inspect the filter for signs of wear or damage. Look for cracks, tears, or stretched pleats. If the cartridge is damaged, it’s best to replace it immediately, as compromised filters cannot offer optimal performance.
 

Bonus Tip: Prevent Calcium Deposits

If your pool water tends to develop calcium buildup, cleaning the filter with a diluted acid solution (e.g., muriatic acid) can help. However, always balance your pool chemistry to prevent scaling in the first place.

Reassembling and Restarting

Once your cartridge is clean and dry, return it to the filter housing. Be sure to follow the manufacturer’s instructions to ensure proper alignment. Secure the housing lid or clamps and close the air relief valve. Turn on your pump and monitor the pressure gauge to ensure everything functions correctly.
