This HotSpring Tri-X filter replaces the 71825 Filter in 1990-current HotSpring spas. The ceramic Tri-X filter delivers better performance and lasts longer than the older paper filters.
This ceramic fiber cartridge filter was introduced in the 2004 Hot Spring high performance spa models. In 2006 the HotSpring Tri-X became available as a replacement for the common polyester filters (aka paper filters). The unique design enables it to filter twice the water per minute than a common filter. You don’t have to clean it as often either! This filter can replace the HotSpring model 71825 filter in all 1990-current Hot Spring spa models, 1998-2002 Hot Spring Hot Spot models and all Hot Spring Solana X, Hot Spring RX, Hot Spring SX & Hot Spring TX spa models.
