Frequently Asked Questions
What are the dimensions of the PD60SL?
The PD60SL measures 7 inches in outer diameter and 17.625 inches in length, with a closed top and open bottom. It provides 60 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 PD60SL?
The PD60SL is interchangeable with C-7403, and OEM equivalents including Doughboy 239-060, Doughboy 2396-060. All of these share the same 7" OD × 17.625" dimensions and closed 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 PD60SL filter cartridge?
The PD60SL (60 sq ft) is sized for smaller pool filter systems. Plan to inspect it every 3 months and replace it every 12-18 months. Heavy debris loads, high bather traffic, or imbalanced pool chemistry will shorten that timeline - if your filter pressure rises more than 8-10 psi above the clean starting pressure, it's time to clean or replace.
How do I clean a PD60SL filter cartridge?
The PD60SL has a closed (solid) top end cap. 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, soak the cartridge in a dedicated pool filter cleaner solution (following the product's dwell time instructions), then rinse completely before reinstalling. Having a spare cartridge on hand lets you swap and soak while the pool stays running.
Which hot tubs and spas use the PD60SL filter?
Refer to your spa's owner manual or the label inside the filter compartment to confirm compatibility. The part number is usually printed on the end cap of the existing cartridge.
