Opting for a salt chlorinator is a superior choice for both your pool and skin. In addition to cost savings on chemicals, it requires minimal maintenance with a 5-7 year replacement cycle on salt cells. Most salt cells have an operating life of 10,000 hours. Proper maintenance will help extend the life cycle of salt cells. Refer to your owner's manual for cleaning instructions and tips on cleaning Pentair salt cells and products that help keep all salt cells cleaner. Explore our recommended models, Gentle Chlor and IC-40, by following this link.
