Crystal Clear Water, Guaranteed.

The debate of cartridge filter vs sand filter often comes down to efficiency and water saving. Cartridge pool filters are more efficient, trapping particles down to 10-20 microns, compared to 20-40 microns for sand. They also don't require backwash pool filter routines, saving thousands of litres of water annually. While sand filters are cheaper upfront and glass pool filter media improves their performance, many modern pool owners find a best pool cartridge filter offers better long-term value, energy efficiency, and superior water clarity.

You should clean your pool filter cartridge when the pressure gauge increases 8-10 PSI above its normal operating pressure, or roughly every 3-6 months during swimming season. The best way to clean a cartridge pool filter is to remove the element, rinse thoroughly with a garden hose to remove debris, and then soak it overnight in a chemical filter cleaner to break down oils and minerals. This routine is key for extending the life of your pool cartridge filter.

Sizing depends on your pool volume and required turnover rate. For example, for a 50,000 litre pool, you must select a filter and pump combination that meets the flow rate requirements. Always opt for a slightly larger filter than strictly necessary, as bigger filters mean less maintenance. A quality cartridge filter pool element, like those made by Magnum Pool Filters, typically lasts between 3 to 5 years with proper, regular cleaning.

If you have a sand or glass pool filter media system, knowing how backwash pool filter maintenance works is essential. First, turn off the pump. Second, set the multi-port valve to 'Backwash' and run the pump for 1-2 minutes until the sight glass runs clear. Third, turn off the pump, set the valve to 'Rinse', and run for 30 seconds. Finally, turn off the pump and set the valve back to 'Filter' before resuming normal operation. You should check how often should you backwash your pool sand filter, which is usually once the pressure gauge rises 8-10 PSI above normal.

Both the Waterco Trimline Cartridge Filter CC75 and the Waterco CC100 cartridge filter use pleated media to provide high-quality filtration, making them excellent choices among Waterco pool filters. The main difference is the filtration surface area and flow rate capability: the CC100 model is physically larger, offers a higher maximum flow rate, and requires less frequent cleaning than the CC75. Mr Pool Man carries replacement cartridges for all Waterco models, so always confirm the correct Waterco filter cartridge size when ordering a replacement CC100 pool filter cartridge.

Cloudy water can often be a sign that your old pool cartridge filter is no longer effective. Over time, the pleats degrade or become permanently clogged with oils, lotions, or fine calcium deposits (even after cleaning pool filter cartridge soaking), preventing proper particle capture. If the problem persists, you definitely need a new pool filter cartridge replacement. You can find high-quality pool filter cartridges for all major brands, including replacement Hayward pool filter cartridges and Jandy CS150 filter replacement units, available through trusted suppliers like Mr Pool Man to restore crystal-clear water.
