Maintain a pristine hot tub without the guesswork with the KGC 6CH-940 Spa Filter 2 Pack. These replacements are designed to fit a range of popular spa models and offer a straightforward, twist-in installation that helps you keep water clarity and comfort in reach after every soak.

Key dimensions and construction

The filters measure 8 1/4 inches in length with a 6-inch outer diameter, a bottom 1 1/2-inch SAE thread, and a top circular handle for quick gripping. The filtration area spans 45 square feet, and the cartridge uses Trilobal Filtration Fabric in a one-piece molded design, delivering a compact, solid filtration profile that is easy to handle during routine maintenance.

With a focus on user-friendly service, the cartridge is engineered to resist cracking and warp, supporting a tidy, low-effort cleaning routine that fits into busy weekend spa care or after-work refresh sessions.

What you may notice in daily use

• Clearer water with reduced particulate buildup after regular use.
• More consistent flow thanks to a robust filtration media and seamless one-piece construction.
• Less time spent fiddling with replacements due to a simple twist-in installation.
• Durable materials designed to withstand routine spa maintenance and cleaning cycles.

Two important aspects of routine care are highlighted here: regular cleaning and proper handling. The improved Trilobal Fabric Filter Structure helps debris penetrate into the pleats for easier washing, and a careful rinse can restore much of the filter’s original performance when done every couple of weeks.

Compatibility and maintenance tips

• Companion models include Pleatco PWW50P3 (Not PWW50P4), Unicel 6CH-940, Filbur FC-0359, Waterway 817-0050, and 25252 variants.
• Always verify fit with the listed part numbers to ensure a secure seal and proper filtration.
• Clean the filter every 2 weeks for optimal spa performance and water quality.
• Rinse thoroughly after washing to remove trapped debris and restore flow.
