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 $610 less than Pentair's OEM replacement cell (about $940 vs about $1,550 on Amazon, read the same day) — the whole reason to go aftermarket on an IC40
- 3.9★ across 77 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
- Its critical reviews are failures, not quibbles: all ten of the newest (written 2026-07-22 to 2026-10-03) are a cell that died at two to six months, a false low-salt reading, or a controller that cannot see it — and on 2026-10-16 its 77 ratings ran 62% five-star, 13% four-star, 2% two-star and 23% one-star
- 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 professional installation); the specialty-retailer APX P40's 'two-year' is one free year and a second with parts at half 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 two to six months.
14 written critical reviews (the critical filter's count) as of 2026-10-16; the histogram puts 23% of the 77 ratings at one star. All ten of the newest critical reviews (2026-07-22 to 2026-10-03) are a dead cell, a false low-salt reading or an automation system that cannot see it · critical reviews read 2026-10-16
“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
FAQ
Who is the EverCrystal Replacement Salt Cell for Pentair IntelliChlor IC40 (40,000 gal) for?
Your Pentair IC40 cell died, you don't run pool automation, and you'd rather spend about $940 than about $1,550 on the OEM cell — a 3.9★ drop-in (down from 4.5★ when we carded it, on a base that has nearly tripled since) with its own onboard salinity sensor.
What do owners say about the EverCrystal Replacement Salt Cell for Pentair IntelliChlor IC40 (40,000 gal)?
3.9★ across 77 owner ratings (Amazon, read 2026-10-16 · early data · listing-wide base). What owners complain about: 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 two to six months.
Who sells the EverCrystal Replacement Salt Cell for Pentair IntelliChlor IC40 (40,000 gal) on Amazon, and can it be returned?
Sold by BACKYARD SUPPLY STORE, shipped by Amazon, when we read the listing on 2026-10-16. Amazon's returns line read: Free 30-day refund/replacement. Sellers and return terms can change, so check both on the listing before you buy.
What is the warranty on the EverCrystal Replacement Salt Cell for Pentair IntelliChlor IC40 (40,000 gal)?
12 months — stated in the listing only. EverCrystal sells from its own store (evercrystalpool.com) as well as Amazon, and publishes no warranty document on either: the store's warranty pages return 'page not found', and the Amazon listing's warranty link goes to Amazon's generic contact-the-seller page. Nothing to survive or lose between channels — but nothing to appeal to either.
Does the EverCrystal Replacement Salt Cell for Pentair IntelliChlor IC40 (40,000 gal) come with a manufacturer warranty?
EverCrystal publishes no warranty document anywhere we can find, so there is no manufacturer term to hold them to beyond the listing itself and the marketplace's own returns window. Nobody can check what does not exist — that is the finding rather than a gap in our research.
Record
- — Audit read: 3.9 stars across 77 ratings (was 4.0 across 69 on 2026-09-15). The eight ratings in between averaged roughly two to four stars, so the September pause in the decline did not hold. $939.99 on Amazon, unchanged; sold by BACKYARD SUPPLY STORE, shipped by Amazon. EverCrystal's own store lists the same cell at $989.99.
- — Re-read on Amazon: ★4.0 across 69 ratings, from 4.0★ across 56 on 2026-08-24 — the first read since launch where the average did NOT fall (the 13 new ratings average about 4.0). The pooled base is now proven rather than assumed: the 20,000-gal sibling listing read the identical 4.0★ across 69 the same day and the listing's variant menu offers only two sizes. The 60,000-gal variant is GONE from the listing — B0GK7XT3M3 redirects to the 20k — though EverCrystal's own store still lists a 60,000-gal cell at $1,157.99. Base shape: 65% five-star, 22% one-star, nothing at two or three.
- — EverCrystal also sells from its own store, evercrystalpool.com, which corrects the August note that it sells only through Amazon. Neither channel publishes a warranty document: the store's warranty pages return 'page not found', and the Amazon listing links only to Amazon's contact-the-seller page. The 12-month term still comes from the listing alone, and we have asked EverCrystal for its written terms.
- — The 12-month term is listing-stated only. This brand sells through Amazon and publishes no manufacturer warranty document we could locate, so online is not a worse channel here — it is the only one.
- — A claim we had published was falsified by the product's own base as it deepened. The rating went 4.5 across 27 in July, to 4.2 across 50, to 4.0 across 56 — the average fell every time more owners arrived. A thin early base flattered it, and we had ranked on that.
- — Critical pass: the failure is communication, not chlorination. Owners report it reading low salt, refusing to report to a Pentair or Hayward automation system, or simply dying at around six months. An aftermarket cell that the controller will not talk to is a cell you cannot use.
