Cleanable, reusable, and durable, Pentair Pleated Filter Cartridges can be used over and over again. Consequently, the cartridge has a longer life span and is more economical - Additionally, it holds dirt better, requiring less cleaning.


Generally, in filtration, "pleated filter cartridges" are commonly used to increase the filtration surface area and enhance the efficiency of the filtration process. Pleated cartridges are made by folding a filter media back and forth in a pleated pattern. This design allows for more contaminants to be trapped and a longer service life compared to flat or non-pleated filters.


The frequency for changing pleated cartridge filters depends on several factors, including the type of application, the level of contaminants in the environment, and the flow rate through the filter. As a general guideline, pleated cartridge filters should be changed or replaced when they reach their capacity and can no longer effectively remove contaminants.


Here are some indicators that it may be time to change the filter:

  • Differential pressure: Monitor the pressure drop across the filter. As the filter captures more contaminants, the pressure drop will increase. When the pressure drop reaches a specified threshold set by the manufacturer, it indicates that the filter is becoming clogged and should be replaced.

  • Flow rate reduction: If you notice a significant reduction in flow rate through the system, it may be an indication that the filter is becoming obstructed and needs replacement.

  • Visual inspection: Check the filter regularly for visible signs of fouling, discoloration, or damage. If you observe any deterioration or excessive contamination on the filter media, it's time to replace it.

  • Scheduled maintenance: In some applications, filter replacement might be part of routine maintenance schedules. Follow the recommended replacement intervals provided by the manufacturer.

  • Specific application requirements: Certain industries or processes may have specific regulations or standards that dictate when filters should be changed. Follow any guidelines or best practices applicable to your industry.

  • Changes in product quality: If you notice a decline in product quality or performance of the system, it might be related to the filter's condition. Consider replacing the filter to ensure optimal filtration.


Here are some common technical specifications for pleated filter cartridges:

  • Micron Rating: The micron rating refers to the filter's ability to remove particles of a specific size. It indicates the smallest particle size the filter can effectively capture. Pleated filter cartridges are available in various micron ratings to accommodate different filtration needs, such as 1 micron, 5 microns, 10 microns, etc.

  • Filter Media Material: Pleated filter cartridges can be constructed using different materials, such as polypropylene, polyester, cellulose, PTFE (Teflon), nylon, and more. Each material offers distinct characteristics and compatibility with various fluids and applications.

  • Filter Size and Dimensions: Pleated filter cartridges come in different sizes and dimensions, commonly ranging from 10 inches to 40 inches in length and 2.5 inches to 4.5 inches in diameter. The size and dimensions are essential considerations for compatibility with your filtration system.

  • Flow Rate: The flow rate of a pleated filter cartridge indicates the volume of fluid it can handle per unit of time. It is usually expressed in gallons per minute (GPM) or liters per minute (LPM) and depends on the filter size and design.

  • Operating Temperature and Pressure: Pleated filter cartridges have specified temperature and pressure limits for their safe and efficient operation. It's essential to use filters that can withstand the conditions of the fluid being filtered.

  • End Cap and Core Material: The end caps and core of the pleated filter cartridge can be made from various materials like polypropylene, stainless steel, or other plastics. These components contribute to the cartridge's structural integrity and compatibility with specific filtration systems.

  • Filtration Efficiency: The filtration efficiency indicates the filter's ability to remove particles from the fluid. It is often expressed as a percentage, representing the proportion of particles removed by the filter.

  • Service Life and Replacement Interval: Manufacturers typically provide an estimated service life for their pleated filter cartridges based on the type of contaminants and operating conditions. It's essential to know the replacement interval to maintain efficient filtration.
