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.
Faucet Filters. Replace your PUR faucet filter every 100 gallons or approximately every two to three months. An indicator on the filter housing alerts you when the filter needs to be changed. To change the filter, remove the housing cap, pull out the old filter and install the new filter in the same direction.
