Frequently Asked Questions
What are the dimensions of the PDO75-2000?
The PDO75-2000 measures 7.125 inches in outer diameter and 10.5 inches in length, with a open top and open bottom. It provides 75 square feet of filtration area. Always measure your existing cartridge or check the label inside the filter housing before ordering - outer diameter and length are the two critical dimensions, but end-cap style must also match.
What other part numbers are interchangeable with the PDO75-2000?
The PDO75-2000 is interchangeable with C-7367, FC-3059, and OEM equivalents including Dimension One 1561-00, Dimension One 01561-00-A, Aladdin 17541. All of these share the same 7.125" OD × 10.5" dimensions and open top / open bottom end caps. When buying a cross-reference, confirm the end-cap style matches - a small difference in cap design can prevent proper seating in your filter housing.
How often should I replace a PDO75-2000 filter cartridge?
At 75 sq ft, the PDO75-2000 has plenty of filtration area for the volume of water in most hot tubs. Under typical residential use (2-4 people, 2-3 times per week), most owners replace it every 18-24 months. Monthly rinsing and a quarterly overnight soak in filter cleaner will keep it flowing freely and extend its life.
How do I clean a PDO75-2000 filter cartridge?
The PDO75-2000 has open ends on both top and bottom, so water flows through freely. Remove the cartridge from its housing and rinse thoroughly with a garden hose, directing the stream at a 45-degree angle between the pleats - work from top to bottom, rotating around the cartridge. Avoid pressure washers, which collapse the pleats and permanently reduce filtration efficiency. For a deeper clean every 3-4 months, soak overnight in a hot tub filter cleaner solution, then rinse thoroughly. Never reinstall a wet cartridge if you're using a cartridge with a closed end - let it dry to prevent trapping moisture inside.
Which hot tubs and spas use the PDO75-2000 filter?
The PDO75-2000 is compatible with the following models: Dimension One Nautilus, Dimension One Reflection, Dimension One Triad. Always cross-check your spa's owner manual or the label inside the filter compartment to confirm the correct part number.
