When to Clean Your Pool Filter Cartridge vs. When to Replace It

As a pool owner, ensuring that your pool filter is clean and functioning properly is crucial for maintaining overall pool health. Proper maintenance of your pool filter is essential, and while regular cleaning is a critical part of this upkeep, there will come a time when the cartridge needs to be replaced. Below are guidelines on how to determine whether your cartridge requires cleaning or if it’s time to invest in a new one.

When to Clean the Pool Filter Cartridge

• The pool filter cartridge should be cleaned whenever the pressure gauge rises by about 8 PSI (pounds per square inch) above its normal operating level.
• As a general practice, aim to clean the cartridge at least once every six months. Keeping a regular schedule will help ensure that you do not overlook this important maintenance task.
• If you observe a change in water quality, inspecting the filter cartridge is vital, as it may need a thorough cleaning.

If you've determined that your cartridge requires cleaning, follow these straightforward steps: First, remove any larger debris from the cartridge surface. Next, immerse the cartridge in a cleaning solution specifically formulated for pool filter cartridges to dissolve the accumulated grime and oils. After soaking for a minimum of six hours, rinse it thoroughly and allow it to dry completely before reinstalling it in the filter tank.

When to Replace a Pool Filter Cartridge

The lifespan of a cartridge can typically range from three to five years, but there are several signs that indicate it might be time for a replacement. Here are some key indicators:

• Changing Water Quality: If your pool water remains cloudy or green despite balancing the chemicals, it is likely time to check the filter cartridge. Each cleaning session can gradually wear down the fibers, allowing finer dirt and debris to bypass the filter.
• Increased Cleaning Frequency: If you find yourself cleaning the cartridge more often due to rising pressure levels, it may be a sign that replacement is necessary. Keep track of when you last cleaned the cartridge; if the cleaning frequency doubles, it’s time to consider a new one.
• Damaged Filter: After cleaning, always inspect the filter for any visible tears or damage. If any is found, the filter may not be effective in removing debris, resulting in a dirty pool.
• Check Filter Bands: Cartridge filters have horizontal bands that maintain the pleat spacing correctly. If any of these bands are loose, falling off, or absent, replacement is required.

For those who prefer not to handle the regular upkeep of cleaning and replacing their filter cartridge, professional services like Pool Scouts can assist in these tasks. Pool Scouts provides filter inspections and cleaning services to ensure your filter and cartridge are in top shape, keeping your pool pristine.
