EverCrystal Replacement Salt Cell for Pentair IntelliChlor IC40 (40,000 gal)
Best value — the aftermarket IC40 cell you can actually buy — The aftermarket replacement cell for a Pentair IntelliChlor IC40 — a genuine drop-in with an upgraded flow switch and onboard temp/salinity sensor, for roughly $560 less than Pentair's OEM cell (about $940 vs around $1,500), for pools up to 40,000 gallons. Two honest catches: no automation (RS-485) integration, and a 12-month warranty.

Pros
- A true drop-in for the Pentair IC40 — same length and union threads, so it swaps in about 15 minutes with no plumbing changes and no special tools
- Onboard temp/salinity sensor and an upgraded flow switch — it reads your salt level itself, so it works even if your OEM power center is also aging
- Roughly $560 less than Pentair's OEM replacement cell (about $940 vs around $1,500) — the whole reason to go aftermarket on an IC40
- 4.0★ across 56 Amazon ratings — an independent, buyable track record unlike the no-name generics, though the average has slipped from 4.5★ as the base doubled
Cons
- Every one of the 7 critical reviews on this listing is a failure or an incompatibility — dead at around six months, or refusing to talk to the controller — and the base has slid from 4.5 across 27 ratings to 4.2 across 50 since we first read it
- No RS-485 / data connection, so it will NOT integrate with automation — Pentair IntelliCenter/EasyTouch, Jandy AquaLink, or Hayward controls won't see it or drive it. If you run automation, buy the OEM Plus40.
- 12-month warranty — level with the OEM cell's 1-yr ONLINE term (the OEM's 3-yr needs a dealer purchase) (and the specialty-retailer APX P40's 2-year); you're trading warranty length for the lower price
- Doesn't publish a rated cell-life in hours or a chlorine-output figure — the OEM quotes ~10,000 hr / 1.4 lb/day; size to your gallons and don't assume
It does not talk to the controller - owners report it reading low salt, refusing to report to a Pentair or Hayward automation system, or simply dying at around six months.
ALL 7 critical cards on a base of 50 are a failure or an incompatibility. And the base has MOVED: it was 4.5 across 27 ratings when we first read it and is now 4.2 across 50, so the 23 newer ratings average about 3.9 · critical reviews read August 2026
“Literally half the cost of a Pentair replacement. After using it so far, no issues at all. Chlorine levels are consistent.”— Jackie L, Amazon · Verified owner
