This ceramic fiber cartridge Hot Spring Tri-X Spa Filter 73178 was introduced in the 2004 Hot Spring high performance spa models.

• In 2006 the 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 71825 filter in all 1990-current Hot Spring spa models, 1998-2002 Hot Spot models and all Solana X, RX, SX & TX spa models
• Dishwasher safe
• No soap. No drying cycle
• No more spraying off your filters outside in the dead of winter
