Review on Culligan D250A D 250A Cartridge Set by Laura Jenkins

These cartridges work well in our (discontinued) Culligan SY-5197 unit, although the Culligan website lists another cartridge for this model (this page has since been updated). from their distant side?). This cartridge appears to be smaller than the other model and does not fill the cartridge holder like the old model. The packaging also says it will last 6 months, versus 2 years for the older model. The old model is incredibly hard to find these days, so it's a worthy replacement until we end up replacing the entire system.
