Intex 58601 Filter Cartridge
Intex OEM number • 30 sq ft • 5.875″ OD × 12.1875″ long
58601 is Intex's number for this cartridge, not a part you have to buy from Intex. The filter itself is a 30 square foot cartridge measuring 5.875 inches across and 12.1875 inches long, and Pleatco, Unicel, and Filbur all build it. If you read 58601 off an old cartridge or found it in your manual, any of the numbers below drops into the same housing.
Intex also lists Type D against this cartridge. Different numbers on paper, same filter in the box.
Fitment notes
1-7/8 inch inner diameter. Intex Type D / Krystal Klear 520 and 530.

Frequently Asked Questions
What filter replaces the Intex 58601?
The PINTD replaces it directly, and so does every cross-reference for it: C-5330. All of them are the same 30 sq ft cartridge at 5.875" outer diameter and 12.1875" long. Buy whichever is cheapest at the time with solid recent reviews. The same cartridge also shows up as Intex Type D, so those are not different filters either.
Is the Intex 58601 the same as the PINTD?
Yes, physically the same filter. Intex 58601 is an OEM number, meaning it is the code Intex put on the cartridge that shipped with the equipment. Intex 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 Intex 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 Intex 58601?
5.875 inches in outer diameter, 12.1875 inches long, with 30 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.
