Product overview
C-4310 is an aftermarket pleated hot tub filter cartridge, 4-1/4 in. in diameter and 4 in. long, with 10 sq ft of filter area. Top: open (2-1/16" ID). Bottom: open (2-1/16" ID). Center opening: 2-1/16 in.
It interchanges with Pleatco PWW10 and Filbur FC-3077.
OEM cartridges it replaces: CMP 25249; Icon Spas 146949; Rec Warehouse 378900; Waterway 817-0010.
Before ordering, measure the old cartridge — overall length, outside diameter and both end fittings. Some catalogs quote the length of threaded top-load cartridges with the thread and some without, so a quarter-inch difference between listings is common. We supply spa service companies, dealers and online retailers: MOQ 50 pcs per part, mixed cartons welcome, and single samples to confirm fit before a production order.

What OEM numbers does C-4310 replace?
POOLPOINT C-4310 is an aftermarket replacement cross-referenced to 146949, 25249, 378900, 817-0010, FC-3077 and PWW10. Those numbers identify fitment only — the part is manufactured by POOLPOINT, not by Unicel.
Is C-4310 a genuine Unicel part?
No. POOLPOINT manufactures compatible aftermarket replacement parts. We are not affiliated with, sponsored by or endorsed by Unicel; the brand name and OEM numbers are used to identify fitment only.
What is the minimum order quantity for C-4310?
MOQ is 50 pcs per part, and mixed cartons are welcome to reach the order minimum. Samples are a separate case — we supply single pieces so you can confirm fitment before committing to a production run.
