Culligan Filter Questions

How do I find my Culligan cartridge model?

Look at the label on the cartridge or the housing, where the model code (such as P5A or S1A) is printed. If you are unsure, email us the code or a photo of the label.

What is the difference between the P5A and S1A?

Per the listings, the P5A is a 5 micron cartridge stated for 8,000 gallons, and the S1A is a 20 micron standard cartridge stated for 16,000 gallons. A lower micron number filters finer particles.

Do Culligan ZeroWater-technology filters fit ZeroWater pitchers?

Check each product page for the pitcher models a filter lists. Do not assume filters swap between pitchers without checking.
