The pool water filter cartridge of a swimming pool, as the core component of the swimming pool filtration system, does not have a fixed and uniform replacement cycle. It mainly depends on the frequency of swimming pool usage, the size of the swimming pool, the degree of water pollution, and the daily maintenance conditions. Properly controlling the replacement time can not only ensure that the swimming pool water quality meets the standard, but also extend the service life of the filtration system and avoid equipment failure caused by aging and clogging of the swimming pool filter cartridge. Generally, it is recommended to replace the pool pleated filter cartridge every 6-12 months in regular usage scenarios. Special circumstances should be adjusted flexibly.
The replacement cycle of pool water filter cartridge varies significantly in different scenarios. For small family swimming pools with low usage frequency and mainly used by family members, the water pollution is relatively light. If regular maintenance such as periodic backwashing and sewage discharge is done well, the swimming pool filter cartridge can last up to 8-12 months by promptly removing hair, impurities, and other substances attached to the pool pleated filter cartridge surface. However, for commercial swimming pools and public swimming pools in residential areas with large traffic flow, there are more hair, sweat, skin care residues, and external dust brought in by swimmers. The pool water filter cartridge's filtration load increases significantly, and it is recommended to replace the swimming pool filter cartridge every 6-8 months. During the peak season in summer with increased traffic flow, it can be shortened to 4-6 months to avoid excessive saturation of the pool pleated filter cartridge affecting the filtration effect.
In addition to referring to fixed cycles, one can also accurately judge whether the pool water filter cartridge needs to be replaced through intuitive phenomena. If the pressure difference of the filtration system significantly increases and the water flow rate drops sharply, even after backwashing and chemical cleaning, there is no improvement, it indicates that the swimming pool filter cartridge is severely clogged inside; if observing that the pool pleated filter cartridge surface is damaged, deformed, aging and yellowing, or the attached pollutants cannot be completely cleaned, it will lead to filter failure; if the swimming pool water becomes turbid, the odor is obvious, the disinfectant effect decreases, and the bacteria and suspended solids in the water exceed the standard, it is necessary to replace the pool water filter cartridge in time. Regular replacement of swimming pool filter cartridge can effectively avoid filter failure, reduce the growth of bacteria and algae, and provide a safe and clean swimming environment for swimmers.
