It is recommended that you clean the filter cartridge of your pool filter every 1 to 2 weeks and replace it completely about once a month. This helps to maintain the optimal performance of your filter pump and ensure that your pool water remains clean and clear.
The package includes 2 filter cartridges, so you always have a clean cartridge on hand. When you remove one cartridge from the filter pump to clean, you can immediately insert the other. This way, you don't have to waste any time and your pool remains continuously well filtered.
