Hot Springs Tri-X Filter Cartridge

(Please Note: Model 73178 has been officially upgraded to the new 79436. You will receive the newest version!)

Upgrade your spa's water clarity with the revolutionary Tri-X filter. Unlike traditional paper filters that only catch debris on the surface, the Tri-X uses three-dimensional depth filtration to trap dirt deeper and keep your water crystal clear for longer.

Why Choose the Tri-X?

• 10x the Filtering Power: Processes ten times more water per square foot than standard paper filters.
• Double the Surface Area: Offers a massive 65 sq. ft. of filtration space (compared to standard 30 sq. ft. filters).
• Built to Last 5+ Years: Durable ceramic media extends your filter life, saving you money and the hassle of frequent replacements.
• Deep Cleaning: Unique 3D design catches microscopic particulates within the depth of the filter, not just on the outside.
