Hot Spring Tri-X 79435 | Next-Gen Highlife Spa Filter

The new Hot Spring Tri-X® filter is a next-generation, patent-pending redesign of spa filtration, engineered exclusively for the Highlife® Collection. It replaces pleated media with a fundamentally different approach — advanced materials and smart engineering that deliver cleaner water, stronger jet performance, and dramatically simpler care.

Filtration is where water quality is won or lost. Every soak leaves behind body oils, lotions, hair, and fine debris, and your filter has to capture all of it before it clouds the water or reaches your plumbing. Traditional pleated filters do that job, but they come with familiar frustrations: debris packs down into the folds, flow gradually falls off, jets lose pressure, and cleaning means working a hose stream through every pleat.

The new Tri-X was built to solve those problems at the source. Its no-pleat, multi-channel design maximizes water exposure and debris penetration, so the filter keeps strong, steady flow to the jets as it works — putting less strain on your spa's system. A chlorine-resistant polypropylene shell and proprietary multi-dimensional felt resist the brittleness and breakdown that wear out conventional filters. And cleaning is genuinely simple: no pleats to pick through, just backflush and rinse.
