The Hot Spring 65 Sq. Ft. Tri-X Element Filter is a factory original replacement cartridge designed for Hot Spring high-performance spa models. First introduced in 2005, the Tri-X ceramic fiber filter quickly became a popular upgrade in 2006 as a replacement for traditional polyester filters.
Engineered with a unique ceramic fiber construction, the Tri-X filter is capable of filtering up to twice the water per minute compared to common polyester cartridges. This advanced design helps improve water clarity while reducing maintenance frequency, meaning you won’t need to clean it as often as standard filters.
With precise dimensions of 6 inches in diameter by 10.5 inches in length and a 2-inch inside hole, this 65 square foot filter element provides a secure fit and dependable performance. For purchasing reference, part number 73178 identifies the individual filter unit, while part number 73250 designates the manufacturer’s case quantity.
