FAQ


For a water filter (swimming pool), the cartridge must be changed when it is clogged, damaged, or when the pressure increases abnormally. Generally, pool cartridges are replaced every 1 to 3 years, or more often depending on usage. An old cartridge reduces filtration efficiency and increases the load on the pump.

Consult our cartridges


To change a filter cartridge, first turn off the pump and release the pressure using the air valve on top of the filter. Then open the cover, remove the old cartridge, and rinse the inside of the housing if necessary. Insert the new cartridge, making sure it is centered and seated firmly in the filter housing. Remember to apply lubricant to the cover gasket. Replace the cover, tighten the clamp, and restart the pump. Check for leaks.



More or less... but severalreliable suppliersoffer cartridgesequally effectivethan that of the supplier. The important thing is toconfirm the exact compatibilitywith yourfilter model.


Still according to the filter model.Pick up thebrand + modelof the filter (label on the tank) or thesupplier codeof the cartridge.

If not, measurelength,outside diameter,inner diameter, and thetype of tips(open/closed, male/female thread).


A filter cartridge typically needs replacing every 1 to 3 years, depending on pool usage, water quality, and filter maintenance. If the pressure rises rapidly, the cartridge remains dirty despite thorough cleaning, or the pleats are damaged, soft, or crushed, it's time for a replacement. A worn cartridge reduces filtration efficiency and can overload the pump.



To maintain good flow, rinse the cartridge with clean water every 2 to 4 weeks, paying particular attention to the pleats to remove sand, oil, and debris. For a deeper clean, soak the cartridge in a degreaser or a cleaner specifically designed for filters, then rinse thoroughly before reinstalling it. Regular maintenance prevents the cartridge from clogging, preserves normal system pressure, and ensures optimal filtration.
