How to find a replacement cartridge for your pool or spa? If you already know your filter cartridge's part number or the replacement number, you can use the search the part number on our product page to quickly confirm whether the filter is compatible. If you do not know the replacement part number for your cartridge, then choosing the right cartridge can be accomplished by measuring your existing one. Use the following steps as a guide 1. Measure the outside diameter of the cartridge in inches (+/- 1/16th inch) 2. Measure cartridge length from end cap to end cap (+/- 1/16th inch). Exclude any handles or extensions. 3. Identify the correct top and bottom type. If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16th inch). If the end cap is closed make note of its identifying features. 4. Make note of the manufacturer and model number of the filter into which the replacement cartridge will be installed. 5. Take note whether or not there is a center core (PVC pipe in center).

Long Service Life, Save Your Money The Poolpure filter can be used repeatedly after proper cleaning and maintenance, which increases the service life of the pool filter and saves money. Review: Good value,easy to use and works very well for me. - Very pleased with this robot. Simple to use and does a good job on my above ground flat bottomed pool. It saves a lot of time compared to using the pool's pump and hose on a long pole. Also means the dirt goes into the robot's filter not the pool's filter. so will pay for itself as the pool's filter clogs up quickly and cost about £100 each. The design is not perfect. not obvious which way the filter fits in and which way round the body fits together. Those are minor quibbles, overall I am delight with how well this cleans my pool. Review: Had a problem but service was excellent - Great little machine. It moves around quickly and does the job well. Much easier than vacuuming with a long hose. I had a faulty switch on my machine second time I used it so Anna from their customer services sent a replacement machine, so service gets 5 stars. ## Features - 【Safety Material】Poolpure filter is tested and certified by IAPMO against NSF/ANSI 50 for safe and eco-friendly material. - 【Replacement Models】Pleatco PRB25-IN / Unicel C-4326 / Filbur FC-2375 / 17-2327 / 100586 / 33521 / 25392 / 303909 / M-4326 / 8172500 / R173429. - 【Product Detail】4OZ media.
