Tri-X Replacement Filter Cartridge

The HotSpring Tri-X filter cartridge 73178 is a high-performance, original equipment manufacturer (OEM) replacement filter for a wide range of HotSpring, Hot Spot, and Solana spas, manufactured by Watkins Wellness. Its unique ceramic fiber construction and advanced 3D media provide superior filtration compared to standard paper filters.

Key features:

• Superior filtration: The 3D ceramic design of the Tri-X filter allows it to filter not just on the surface, but also through the depth of the media, which captures more debris and finer particles. This results in clearer water with less maintenance.

• Extended lifespan: With proper care, the Tri-X filter can last up to five years, significantly longer than a standard paper filter.

• High flow rate: This unique filter design allows for twice the water per minute to pass through compared to traditional paper filters, which reduces strain on your spa's pump.

• Easy cleaning: For maintenance, the filter can be rinsed with a hose or placed in a dishwasher on the rinse cycle only, with no soap or heat.
