Clearwater 2 200 Filter Cartridge
Clearwater OEM number • 200 sq ft • 8.9375″ OD × 21″ long
2 200 is Clearwater's number for this cartridge, not a part you have to buy from Clearwater. The filter itself is a 200 square foot cartridge measuring 8.9375 inches across and 21 inches long, and Pleatco, Unicel, and Filbur all build it. If you read 2 200 off an old cartridge or found it in your manual, any of the numbers below drops into the same housing.

Replacements for the Clearwater 2 200
Each button searches Amazon for one of the numbers this cartridge is sold under. The OEM version is usually the most expensive of the set and the aftermarket versions are the same physical filter, so it is worth checking all of them before you order.

Frequently Asked Questions
What filter replaces the Clearwater 2 200?
The PWWCT200 replaces it directly, and so does every cross-reference for it: C-8419, FC-1288. All of them are the same 200 sq ft cartridge at 8.9375" outer diameter and 21" long. Buy whichever is cheapest at the time with solid recent reviews. The same cartridge also shows up as Waterway 817-0200NB, so those are not different filters either.
Is the Clearwater 2 200 the same as the PWWCT200?
Yes, physically the same filter. Clearwater 2 200 is an OEM number, meaning it is the code Clearwater put on the cartridge that shipped with the equipment. Clearwater does not manufacture cartridges. Pleatco, Unicel, and Filbur do, and they sell the identical part under their own numbers at a lower price. Match the dimensions against your old cartridge before ordering and you are covered.
Do I have to buy the Clearwater version?
No. Nothing about the housing requires an OEM-branded cartridge, and the warranty on your equipment is not voided by using an aftermarket filter that meets the same spec. The reason to buy OEM is convenience, not performance. The reason not to is price, which is often a meaningful gap for an identical part. What matters is that outer diameter, length, and end-cap style all match.
What size is the Clearwater 2 200?
8.9375 inches in outer diameter, 21 inches long, with 200 square feet of filter media. Both measurements need to land within about an eighth of an inch, and the end caps have to match so the cartridge seats correctly when you close the lid. Measure your old one rather than trusting a number that has worn off the label.
