My Buying Guides on Intellichlor Plus 40
What I Looked For Before Buying
When I first started looking at the Intellichlor Plus 40, I focused on the basics that matter most to me: pool size compatibility, ease of installation, chlorine output, and long-term maintenance. I wanted a salt chlorination system that could keep my pool water clean without constant manual dosing, and I also needed something that would fit my existing setup without creating extra work.
Why I Considered the Intellichlor Plus 40

For me, the biggest appeal was the idea of more consistent chlorine production and less time spent handling chemicals. I also liked that it is built for reliability, which made it feel like a practical choice for regular pool use.
Pool Size and Capacity
One of the first things I checked was whether the unit could handle my pool’s size. I learned that choosing a chlorinator that matches or slightly exceeds my pool’s needs is important for maintaining proper sanitation. If the unit is undersized, I would end up running it harder than necessary, which could reduce efficiency and shorten its life.

Still, I made sure to review the plumbing and electrical requirements before buying so I would not run into surprises later.
Maintenance and Cell Life
For me, maintenance is a major factor in any pool product purchase. I wanted something that would not demand too much attention, but I also knew that salt cells eventually need cleaning and replacement. I looked for information on how often the cell may need servicing and what kind of upkeep would help extend its life. That helped me think about the real long-term cost, not just the upfront price.
Water Quality and Performance
I was interested in how well the Intellichlor Plus 40 could keep water clear and balanced.

Before making a decision, I checked whether the Intellichlor Plus 40 would work with my current pool equipment. Compatibility matters because I did not want to buy a unit that would require extra adapters, control systems, or major modifications. I recommend looking closely at your pump, filter, and control setup before committing.
Cost and Long-Term Value
I did not want to focus only on the purchase price. I thought about the total value over time, including reduced chemical use, possible energy efficiency, and the cost of future maintenance. For me, a product like this makes sense only if it saves time and effort while still delivering dependable results.
What I Would Check Before Finalizing the Purchase
Before I buy, I always double-check:
- My pool’s exact gallon capacity
- Electrical and plumbing requirements
- Warranty coverage
- Replacement cell availability
