How Do Pool Cartridge Filters Work?
Pool filter cartridges work as part of a larger pool filter system. The job of a cartridge filter is to strip unwanted particles, oils and debris from your pool water. Keeping your pool filter cartridge clean not only helps keep your pool water clean, but helps keep the cartridge filter working efficiently for years. 
 
When & How to Clean Your Pool Filter Cartridge
Pool filter cartridges should be cleaned on average, every six months, or when your filter pressure gauge has increased about 8 to 12 PSI above the recommended starting pressure of your pool filter.
 
To clean your pool filter cartridge, you’ll want to first turn off the filtration system and remove your pool filter cartridge. Remove any large dirt or debris, then clean the pool filter cartridge with the necessary filter cleaning accessories, checking for tears, cracks or damage each time.
 
After you’ve successfully cleaned your pool filter cartridge, allow it to fully dry before inserting it back into the filter tank. If waiting for your filter to dry isn’t an option, consider keeping a pool filter cartridge replacement on hand, this way you’ll always have a clean, dry cartridge to use right away. 
 
When to Replace Your Pool Filter Cartridge
On average, your pool filter cartridge should last you 3-5 years, depending on the demand placed on it. A damaged filter can affect the overall performance of your filter and subsequently how clean your pool is. Here are some telltale signs that it may be time to replace your pool filter cartridge.
 
If your filter cartridge is worn or damaged (broken end caps, fraying pleats, or degrading material) we recommend replacing it. If the cartridge has stains that do not come out with cleaning, it means your filter is saturated with oils and should be replaced.
