Pool filter cartridges can run for about 2,000 hours for a filter pump. Usually filter cartridges have to be replaced once every 1 or 2 years. The life of the filter will be less if you enter the pool with suntan lotion, deodorants, mousse, styling gels, and other damaging chemicals.
A correctlysized pump, however, moves the water through the system and sends it back to the pool, filtered, cleaned and ready for swimming. A pool pump should run a minimum of 12 hours a day to turnover, or filter, all the water in a pool. A number of factors can reduce the amount of time required to filter the pool, one of which is the gallon size of your pool. How big your pool is determines how quickly your pump can complete a full turnover of all the water.
