When quality matters for your hot tub, a dependable filter can make a noticeable difference in clarity and feel. The Mamokin 4CH-935 Spa Filter arrives as a practical 2-pack, giving you ready replacements and minimizing downtime between maintenance sessions. Built to address common filtration needs, this filter helps you keep the water inviting for longer stretches of time without the guesswork of trying multiple brands.

Designed to slot into many standard spa housings, it replaces popular models such as Pleatco PWW35L, Unicel 4CH-935, Filbur FC-0170, SD-01235, Waterway 817-4035, and related units. Before you order, confirm the length, outside diameter, and thread size to ensure a snug fit. The listed measurements are about 9-1/4 inches long, with an outer diameter near 4-15/16 inches, a top handle for easy handling, and a bottom 1-1/2 inch female SAE thread.

The filter’s performance rests on a thoughtfully engineered element. Mamokin uses an improved trilobal fabric filter structure that’s designed to be more straightforward to wash and renew.
