Industry Information
  • Product Details

Pool filters are essential add-ons to your commercial and private pools that will provide you with clean and safe waters for swimming. Pool cartridge filters, in particular, are one of the most popular variants. These cartridge filters are designed to capture and collect debris, dirt, and other solid contaminants from your pool waters. 

You may want to know how these pool cartridge filters are designed and what materials they incorporate. Here is a complete guide to the various materials put to use: 

Materials Used To Make Pool Cartridge Filters

1. Polyester

Polyester is one of the most commonly used in manufacturing cartridge pool filters, specifically due to its ability to resist chemicals, abrasion, and higher temperatures. It can further repel water, mold, mildew, and UV radiation, all essential qualities needed for materials used inside or near swimming pools. 

Most of the cartridges inside these pool filters are made from spun polyester. Water that needs to be filtered passes through the polyester cartridge pool filter which will filter out any contaminants, dirt, and debris. Any remaining microscopic bacteria are killed by chlorine.

2. Polypropylene

Polypropylene is another popular material used to manufacture pool cartridge filters. It can easily remove dirt, sand, mud, and other solid contaminants from your pool water. It is renowned for its ability to resist pool water chemicals and salt water, and can even withstand higher temperatures.

You will also find several different variants using this material, including wound cartridges, pleated cartridges, and spun filter cartridges. 

3. PVC

Polyvinyl chloride, also known as PVC, is commonly used in creating the external piping of the swimming pool filter. PVC has the required robustness and impact strength to withstand incoming water pressure. It also shows impressive resistance to chemicals, water, and high temperatures, making it a well-fitting material. 

PVC isn’t just used on the pool filter exterior; it is also used to make the inner core of the filter cartridges, around which polyester is spun. It is further used to make the end caps of the pool cartridge filters, which prevent water from leaking from the mechanism.

4. Stainless Steel

Most of the exterior cartridge filter tanks or canisters are made of stainless steel. Within these stainless steel canisters, you may find as many as 1-15 or more cartridges. Stainless steel is typically used since it offers more custom fabrications and can be altered down the road if needed. They are also durable and show resistance to corrosion, making them a popular choice. 

5. Fiberglass

Fiberglass is another material considered superior to stainless steel when manufacturing cartridge filter tanks. Fiberglass materials show superior mechanical and chemical resistance, do not rust or corrode, and can withstand water treatment chemicals. They are also nearly 3 times lighter than stainless steel while showing the same durability. 

Final Thoughts

Cartridge pool filters consist of a cartridge fitted inside the cartridge pool filter, which captures debris when pool water flows through. The mesh-like materials can capture contaminants as small as 10 microns and return clean, healthy swimming waters to the pool. These pool filter cartridge materials are actually quite durable, especially if you source your filter from a quality supplier. A high-quality pool cartridge filter such as the Poolking Single Element Cartridge Filter can last you 5 years or more with proper care.
