Cartridge Filters

Pool Cartridge Filters 

Pool Cartridge Filters come in a wide range of sizes to suit spas to large swimming pools. Cartridge filters collect impurities in a porous cylinder, usually made from polyester. 

Pool Cartridge Filters have some advantages over Pool Sand Filters:

  1. Cartridge filters are compact, which means they can fit into tight locations.
  2. They require less work to install as no backwash line, and no media is required to fill them. As cartridge filters can not be back washed and must be cleaned by hand, far less water is used than sand filters.
  3. They can handle higher flow rates than sand filters, making them suitable for spas and applications with high flow pumps. 

Pool Cartridges are not as popular as Pool Sand Filters as there is more maintenance to keep clean. Usually, the cartridge filter element will need to be removed each month and cleaned with a hose. The system needs to be turned off, closing necessary valves, removing cartridge lid, then the cartridge, cleaning and putting it all back together again. Occasionally the pool owner will require a specialised cartridge cleaner to clean the cartridge.

Waterco Cyclone

An excellent option to reduce maintenance is a Waterco Cyclone. The Waterco Cyclone is a centrifuge that spins out a lot of dirt before making it to the cartridge, reducing the cartridge's cleaning and extending the cartridge life. 

Water Savings

A normal-sized pool usually has a 1 Hp pool Pump which will have a flow rate of roughly 200 litres per minute. A backwash usually takes 5 minutes to complete. Water savings would be 1000 litres per month, making cartridge filters popular during times of water restrictions.  


We stock a wide selection of Pool Cartridge Filters. Cartridge Filters are compact, working well when limited for space, and unable to use a backwash line to the sewer. Our brands include Astral Pool (Hurlcon), Waterco, Onga, Zodiac, and Davey.
