The Culligan SY-2000 has been discontinued. The D-130 filter set has also been discontinued but the two filters (the
D-10 and the
D-30) that made up the D-130 set can still be purchased below.
If you are looking for a new filtration system, there are a couple of new under sink filter options below. For a similar system from a different manufacturer, the
Pentek US-1500 water filtration system can be purchased below. Culligan has replaced the SY-2000 with the
Culligan US-EZ-4 which has the new easy change technology and better filtration.
