Swimming pools are a great source of fun and relaxation for many people, but they do require some maintenance to keep them in good condition and this maintenance is essential for ensuring that your pool is safe and enjoyable for all users. One important aspect of pool maintenance is cleaning the cartridge filters, which are responsible for removing dirt and debris from the water. In this guide, we’ll go over everything you need to know about how to clean pool cartridge filters, including the tools and supplies you’ll need, the steps involved, and some helpful tips for keeping your filters clean and functioning properly.

Before we get into the details of how to clean your pool filters, it’s important to understand how they work.

How Cartridge filters work to clean your pool 

Cartridge filters are made up of a series of pleated paper or fabric filters that are housed in cylindrical housing. Water from the pool is pumped through the filters, which trap dirt, debris, and other contaminants, allowing clean water to flow back into the pool. Over time, these filters can become clogged with dirt and debris, which can reduce their effectiveness and cause problems with the overall circulation of the pool. That’s why it’s important to clean them on a timely basis.

So, how often should you clean your pool cartridge filters? It’s generally recommended to clean them every month or two, depending on how heavily the pool is used and the local climate. If you have a lot of leaves and debris in your pool, you may need to clean the filters more often. On the other hand, if you have a small, well-maintained pool that is used infrequently, you may be able to go longer between cleanings.

In this guide, we’ll go over everything you need to know about cleaning your pool’s cartridge filters. From the tools and supplies, you’ll need to know the best way to clean pool filter cartridges, we’ve got you covered now that you have everything you need, it’s time to get started. Follow these steps to clean your pool cartridge filters:

Step 1: Gather your materials

Before you start the cleaning process, make sure you have all the necessary materials on hand. You will need:

  • A hose with a high-pressure nozzle: This will help you blast away dirt and debris from the filters.
  • A filter cartridge cleaning solution: These solutions are specifically designed to remove dirt and grime from cartridge filters and can be purchased at most pool supply stores.
  • A large bucket: You’ll need a place to soak the filters before cleaning them.
  • A pair of gloves: Protect your hands from the dirty water and chemicals you’ll be working with.
  • A towel or rag: This will come in handy for drying off the filters after cleaning.

Step 2: Remove the cartridge filter from the pool

The first step in cleaning your cartridge filter is to remove it from the pool. Depending on your filter system, this may involve loosening bolts or clips, or simply lifting the filter out of the filter housing. Follow the instructions in your filter manual to remove the cartridge filter from the pool.

Step 3: Rinse the cartridge filter with a hose

Once you have removed the cartridge filter from the pool, it is time to start the cleaning process. Begin by rinsing the filter thoroughly with a hose, using a powerful spray nozzle to remove any loose dirt or debris. This will help to loosen any stuck-on dirt and make it easier to clean the filter.

Step 4: Soak the cartridge filter in a cleaner or degreaser

After rinsing the cartridge filter, it is time to give it a deeper clean. Fill a bucket or large container with a pool filter cleaner or degreaser, and then place the cartridge filter inside. Follow the instructions on the cleaner or degreaser for how long to soak the filter (usually around 15-20 minutes).

Step 5: Scrub the cartridge filter with a brush

After soaking the cartridge filter, use a brush with stiff bristles to scrub the filter thoroughly. Pay particular attention to any areas where dirt or debris may be stuck, such as the pleats or folds in the cartridge. Use a back-and-forth motion to loosen and remove any dirt or debris.

Step 6: Rinse the cartridge filter again

Once you have finished scrubbing the cartridge filter, rinse it thoroughly with the hose again to remove any remaining dirt or cleaner. Be sure to rinse the filter until the water runs clear, indicating that it is clean.

Step 7: Dry the cartridge filter

Before reinstalling the cartridge filter in the pool, it is important to allow it to dry completely. This will help to prevent any residue or dirt from being carried back into the pool when the filter is reinstalled. Place the cartridge filter in a sunny spot and allow it to dry for a few hours, or overnight if possible.

Step 8: Reinstall the cartridge filter in the pool

Once the cartridge filter is dry, it can be reinstalled in the pool. Follow the instructions in your filter manual to properly install the filter back in the filter housing. By following these steps, you can easily clean your swimming pool’s cartridge filters and keep your pool water clean and clear all summer long.
