When I decided to upgrade my pool system, the Pentair Intellichlor IC40 Salt Cell quickly became my top choice. If you’re considering this salt cell, here’s what I learned from my experience to help you make an informed decision.
Understanding What the Intellichlor IC40 Is
The Intellichlor IC40 is a salt chlorinator cell designed to work with Pentair’s IntelliChlor system.

Compatibility with Your Pool System
Before purchasing, I made sure the IC40 was compatible with my existing Pentair IntelliChlor control unit. The IC40 is designed for pools up to 40,000 gallons, so it’s perfect for medium to large residential pools. It’s important to check your pool size and control system to ensure a smooth fit.
Installation and Maintenance
Installing the IC40 was straightforward for me. It fits easily into the existing chlorinator housing, and the cell’s design allows for easy removal and cleaning. I learned that regular cleaning of the cell with a mild acid solution helps maintain efficiency and prolongs its lifespan.

Customer Support and Warranty
Pentair offers a solid warranty on the IC40, typically around 3 years. I also found their customer support helpful when I had questions during installation. Having reliable support gave me extra confidence in my purchase.
