The Salt Cell Cost Index
A salt chlorinator's cell is a consumable — it wears out every 3–7 years, and the replacement can cost more than the system did. Cost guides shrug with ranges ("$300–$1,800, lasts 3–7 years"); nobody shows the per-model math. This is the actual table — for whole systems and the aftermarket-vs-OEM replacement cells — so you can compare on cell cost per year, not sticker price. Genuine cells run ~$70/yr to ~$310/yr; the aftermarket cells cost less up front but don't publish a rated life, so their true cost-per-year is unknowable — which is itself the buyer-beware.

How to read this table
Cell cost per year is the number that decides it. Divide the replacement cell's price by its life. We cost every genuine cell on the same ~10,000 hours (~5 years): CircuPool used to rate its cells at 15,000 hours but withdrew that figure in 2026, so no maker here publishes a longer life we can cite. On that basis the CircuPool cells, at $494–$699, come to ~$99–$140 a year; the dealer-brand cells, at $699–$1,550, to ~$140–$310. Over a decade that spread is bigger than the price difference between the systems themselves. Oversize the cell to ~2× your pool volume and it lasts longer still.
Aftermarket cells: cheaper sticker, unknowable cost-per-year. A dead cell sends you shopping, and aftermarket replacements undercut the genuine article — the EverCrystal drops into a Pentair IC40 for about $940 (vs ~$1,550 OEM), and the Maureen fits a Hayward T-15 for about $450 (vs ~$1,099 genuine). But neither publishes a rated cell life, so you can't run the cost-per-year math on them — which is exactly the gamble. On Pentair the aftermarket usually wins (the OEM is pricey and the aftermarket is proven); on Hayward the genuine TurboCell is worth the premium (2× the chlorine per Hayward, NSF-certified, and a far larger proven base).
The DIY-install penalty is the trap nobody prices in. Pentair and Hayward cut the warranty on an online-bought unit to one year, parts only (Pentair also for a unit not professionally installed), against three years through a dealer — the low online price costs you two years of cover. Aftermarket cells carry their own warranty and no such penalty. CircuPool sells direct with no self-install penalty, part of why it wins our salt chlorinator showdown. Pentair buyers should also check the manufacture date: units made before Oct 20, 2025 carry a firmware bug (bulletin A00709) — buy through a dealer who can verify the date.
