Product details

Unicel C-7459-4 is a four pack of replacement filter cartridges for the Jandy CL340 and CLV340 cartridge filters. One pack covers a full element change.

Why a set of four

The CL340 runs four cartridges around a central manifold, and they share the flow between them. When one is new and three are loaded, the new element takes more than its share and wears early while the tank still runs high on pressure. Changing all four keeps the load even and gives the filter its full clean cycle back.

When to replace

Cleaning buys back most of the flow for a while. The point to replace comes when a proper soak and rinse no longer drops the pressure gauge back near where it read on a clean filter, or when the pleats have gone soft, torn or permanently gray.

Questions and answers

What people ask about this product, answered by our pool techs.

How many cartridges are in this pack?
Four. Unicel C-7459-4 is the four pack, which is a full set for the filter.
Will these fit a CLV340?
Yes. The set is listed for the Jandy CL340 and the CLV340.
Should I replace all four at once?
Yes. A filter running a mix of old and new elements loads unevenly, so change the complete set together.
How do I know the cartridges are finished?
When a proper cleaning no longer brings filter pressure back near its clean starting point, the elements are spent and cleaning again will not help.
