About This Item
The Unicel 6CH-940 is a 6000 Series 45 sq. ft. replacement filter cartridge built for top-load and front-access spa skimmer housings that thread onto a 1-1/2" SAE male connection. Featuring 225 pleats of 3 oz. Reemay 2033 polyester media, this cartridge delivers thorough debris capture and dependable water clarity across a wide range of hot tub and portable spa applications.
Unicel rates this cartridge at 45 sq. ft. using precise measurement standards. It is a direct cross-reference replacement for competing brands' 50 sq. ft. cartridges, including the Pleatco PWW50 and Filbur FC-0359. Performance and fit are equivalent — always confirm by measuring your existing cartridge's length, outer diameter, and thread type.
⚠️ IMPORTANT: Some Installations Require TWO Cartridges
Certain dual-cartridge front-access skimmer housings (such as the Waterway Double Port Front Access Skim Filter and select models from Apollo, Belize, Canspa, CMP Double Port, H2O, Haven, Phoenix, Santa Barbara, and Sunbelt Spas) use two 6CH-940 cartridges installed side-by-side for a complete filter service. Check your skimmer housing or existing cartridge count before ordering. If your housing uses two, add 2 units to your cart.
