Pros
- The cell economics that win the calculator: a $699 cell rated 15,000 hr (CircuPool calls it ~50% longer-lasting than other brands) works out to ~$100/yr — a fraction of Pentair's ~$300 or Hayward's ~$220
- No DIY-install penalty: buy it online and install it yourself without voiding the 7-year warranty — unlike Pentair and Hayward, which limit or void warranty on online/self-installed units
- The highest-rated system here at 4.5★ across 161 Amazon ratings — above Solaxx (4.4), Hayward (4.2) and Pentair's early-batch 3.6
- Highest output (2.0 lb/day) and biggest capacity (45,000 gal), so it's already oversized for a typical pool — exactly the headroom the 'oversize the cell' rule calls for
Cons
- Owners across the CircuPool RJ line report cells quitting between the first season and about three years — against a cell rated 15,000 hours — and several describe the 8-year warranty as hard to claim. Treat the rating as a rating, not a promise
- Direct-to-consumer brand with a smaller local dealer/installer footprint than Pentair or Hayward — more of the install and troubleshooting falls on you
- Local pool techs reach for Hayward parts by reflex, so it has less name recognition on the service side
- Pricier system (~$1,695) than CircuPool's smaller EDGE line — for a typical or smaller pool the EDGE-25 is the cheaper, right-sized buy
Cells quitting between the first season and about three years, and owners describing an eight-year warranty that is hard to actually claim. ⚠️ SCOPE: this is the CircuPool RJ-series PARENT pool, not a read of the RJ-45 Plus alone — but RJ45+ owners are named in it, and cell life plus warranty are precisely what this pick is recommended on.

What is the warranty on the CircuPool RJ-45 Plus Salt Chlorine Generator?
7 yr prorated parts (year 1 free; years 5–7 at 80% of base price) — no dealer or DIY clause
Record
- — Warranty re-read on CircuPool's own RJ PLUS manual: the seven years are prorated — parts free in year one, then the owner pays 20/40/60% of base price in years two to four and 80% in years five to seven. No purchase-channel or DIY clause anywhere in the document. CPSC checked clean the same day.
- — Corrected a false comparative claim on this card, and pinned the warranty to what actually preserves it: seven years, kept if you self-install. Cell type confirmed titanium. The critical tail runs against that term — cells quitting between the first season and about three years, with owners describing a warranty that is hard to actually claim.
- — We had been penalising a rival for a pooled rating while our own winner pooled too. The CircuPool figure was retired down to 4.5 across 161 with the pooled flag on it. A standard applied to one product and not another is not a standard.
- — The rating was invalidated by the listing moving underneath it. We read 4.5 across 341 in June off B01F41OY1K, which was then the RJ45+ page; by July that ASIN was serving a different model. The buy link moved to CircuPool brand-direct while Amazon was out of stock or showing the wrong unit.
