Clear Choice 6.00"x9.25" Pool/Spa Cartridge Filter — 4-Pack

What you get: a set of four replacement cartridge filters, each sized at 6.00" diameter by 9.25" length. They are intended as drop-in replacements for compatible hot tub and pool filtration systems that accept this size and connection style.

Construction and materials: each cartridge is built using industry-standard 3 oz Reemay spunbond polyester filter media. The media is manufactured without binders to maximize usable surface area. Every cartridge has 180 pleats, delivering approximately 40 square feet of filtration fabric per element for effective debris capture and improved water clarity.

Fit and installation: each filter includes a molded top handle to make removal and installation easier, and a 2-inch male pipe thread (MPT) at the base for a secure connection to compatible housings. The dimensions and connection style make these cartridges a direct fit for Master Spa Twilight systems and other units that use the same 6.00" x 9.25" specification.

Compatibility notes: besides Master Spa Twilight, these cartridges are also compatible with certain OEM and aftermarket replacements listed under designations such as Other X268365 and PMA40L-F2M. Always verify your original filter’s dimensions, thread type, and clearance before replacing to ensure proper fit and sealing.

Maintenance and lifespan: under normal use and routine maintenance, each cartridge is intended to provide around 12 months of filtration performance, depending on water quality and usage patterns. Buying the four-pack gives you replacements on hand and spreads the cost over multiple change cycles.
