And this blog will help you to figure out all these questions by introducing all knowledge about pleated filter cartridges, and help you choose the right filter cartridges based on your real needs.

What is a pleated filter cartridge?

The pleated filter cartridge is a means of filtration that effectively prevents sedimentation in water. The design of pleated depth cartridges creates more surface area, which increases loading capacity and permits higher flow rates with low differential pressure.

The pleated cartridges are widely utilized as a prefilter to pleated membranes or as a polishing element to depth type media in a typical process flow.

How does a pleated filter cartridge work?

how filter cartridge work

Due to their high efficiency and high flow rates, pleated filters are very effective at delivering surface filtration. Media with depth characteristics that enhance particle retention can be securely packed into the cartridge for a maximized surface area by adopting a pleated design.

As the particle forms a “cake” across the surface of the filter, as much material as possible is retained.

At this point, the particulate is sieved and caught by the media, which can have micron ratings as low as 0.22 and as high as 100 by Brother Filtration. Frequently, a support layer and a final filtration layer are combined to maximize the efficiency and effectiveness of the filtration process.

What is advantages of pleated filter cartridge?

For many special industries, such as oil and power plants, we have also designed and manufactured many depth pleated filter cartridges suitable for them. Since they are pleated cartridges, they have a larger filtration area, and we also use high-quality materials to make them handle various conditions with ease.

  • High-efficiency removal at low micron ratings
  • Higher loading capacity and higher flow rates
  • Nominal and absolute filtration availability
  • High dirt-holding capacity
  • Free of additives
  • No media migration

Which industries are pleated filter cartridge mainly used for?


Depth pleated filter cartridges can be widely used in various industries such as:

  • Prefiltration for SWRO
  • Oil & Gas
  • Power generation condensate system
  • Petrochemicals
  • Food & Beverage
  • Pharmaceutical
  • Municipal water

How to select the most suitable pleated filter cartridge?

There are five factors that impact on the selection of pleated filter cartridge. It is important to read the following information.

The first thing you need to consider is precision, which determines what kinds of particles can be removed. Then, you think about the differential pressure and flow rate you need.

And don’t forget to take dirt-holding capacity into account. When you have consider all the things mentioned above, you will know which pleated filter cartridge is best for your application.

It’s necessary to keep in mind that there isn’t always a straightforward solution to the question of what kind of filter cartridge is ideal for removing contaminants. It is crucial to keep your current project in mind when selecting the right filter because the appropriate filter will vary depending on the specifications.


Pleated filter cartridges have their own advantages and benefits, when applied to suitable industries, they can perform great filtration effects. Owing to the pleated structure, pleated filter cartridges have a larger filtration surface, improving filtration efficiency.
