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
- 4.5★ across 27 Amazon ratings — an independent, buyable track record, unlike the no-name generics
Cons
- 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 — shorter than the OEM's 3-year (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
