Frequently Asked Questions

What are the dimensions of the PA106?

The PA106 measures 7 inches in outer diameter and 25.5 inches in length, with a open top and open bottom. It provides 106 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 PA106?

The PA106 is interchangeable with C-7488, FC-1226, and OEM equivalents including Hayward CX880XRE. All of these share the same 7" OD × 25.5" 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 PA106 filter cartridge?

At 106 sq ft, the PA106 is a large-format pool filter cartridge. In a residential pool with balanced chemistry and regular backwash cycles, most owners get 18-24 months of service before replacement is needed. Inspect the pleats every 3-4 months - if you notice channeling, torn fabric, or the cartridge won't rinse clean, replace it regardless of age.

How do I clean a PA106 filter cartridge?

The PA106 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, 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 PA106 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.
