Product details
The Unicel C-8425 is the replacement filter element for the Jandy CS250 cartridge filter. It carries 250 square feet of 4 oz media on an element measuring 8-15/16 inches across and 33-1/8 inches long.
What the media area buys you
Square footage is what sets how long the filter runs between cleanings and how fine a particle it can hold without choking. A full 250 square feet in a CS250 is what the filter was sized around, so the pump sees the pressure drop the system was designed for rather than fighting an undersized element.
When to change it
Cartridges do not usually fail, they fill in. The fabric loads with oils and fine debris that no amount of hosing brings back, and the first sign is filter pressure that climbs sooner after every cleaning while the returns get weaker. When cleaning no longer drops the pressure back to where it started, the element is done.
Match the model
Unicel builds this family in several sizes for the Jandy CS filters. Check the model number on your filter body before ordering, because a 250 element will not serve a smaller CS housing.
