The Waterway® Clearwater II cartridge size is identified by the number on your filter tank (75, 100, 125, 150, or 200).
If the tank label is missing, check the part number printed on your existing cartridge or measure the cartridge’s outside diameter, length, and end-cap style to identify the correct replacement.
Excel Filters offers replacement cartridges for Clearwater II systems based on the original cartridge specifications to ensure proper fit and performance.
The easiest way to tell is by the cartridge part number printed on your existing filter.
Waterway® Clearwater II cartridges typically use 817-series part numbers with an “N” suffix. ProClean cartridges use different part numbers and end-cap configurations.
If you are unsure, compare your existing cartridge dimensions and part number before ordering.
No. Clearwater II cartridges are available in multiple sizes, and each size uses a different cartridge length and filtration area.
Always match your replacement to your existing Clearwater II tank size, cartridge part number, or measurements to ensure the correct fit.
