Hot Spring Highlife 71825 | 30 sq ft Spa Filter

The Hot Spring Highlife 71825 filter cartridge is the factory-original replacement for a wide range of Hot Spring spas. With 30 square feet of filtration across 124 pleats of heavy-duty polyester, it delivers more efficient filtration and better water clarity — so you spend less time cleaning and more time enjoying your hot tub.

Filtration is the quiet backbone of clean spa water. Every soak leaves behind body oils, lotions, hair, and fine debris, and the cartridge is what pulls all of it out before it clouds the water, feeds bacteria, or coats your plumbing. Let a filter get worn or clogged and the effects spread: dull water, higher chemical use, weaker jets, and a pump and heater working harder against restricted flow.

Hot Spring builds its spas as hydraulically balanced systems — matching filter fabric to water flow — and they filter 100% of the water, 100% of the time. That's why a factory-spec cartridge matters: correct filtration area and flow keep your filtering efficient, your jet pressure right, and your pump happy. Watkins builds this filter from a heavy-duty polyester chosen to outlast generic alternatives, and like all Hot Spring filters it's made in the USA.
