Frequently Asked Questions
What are the dimensions of the PCS75N?
The PCS75N measures 8 inches in outer diameter and 13 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 PCS75N?
The PCS75N is interchangeable with C-8475, FC-3320, and OEM equivalents including Coleman/Maax 100594, Coleman/Maax 3301-2262, Coleman/Maax 17513. All of these share the same 8" OD × 13" 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 PCS75N filter cartridge?
At 75 sq ft, the PCS75N 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 PCS75N filter cartridge?
The PCS75N 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 PCS75N filter?
The PCS75N is compatible with the following models: Coleman Series 7000, Maax Series 7000. Always cross-check your spa's owner manual or the label inside the filter compartment to confirm the correct part number.
