The NEW Tri-X holds more particles than the older Tri-x but this does not deny performance. Tradiitonal filters and the old Tri-X would reduce jet performance as particles hit it/as it got dirty. The durability has been tested against the old Tri-X with slower degradation and therefore a longer lifespan.
Compatible models include:
- Hot Spring Aria and Aria NXT (All years)
- Hot Spring Envoy and Envoy NXT (All years)
- Grandee and Grandee NXT (All years)
- Jetsetter and Jetsetter NXT (All years)
- Prodigy (All years)
- Sovereign (All years)
- Summit (All years)
- Triumph (All years)
- Vanguard (All years)
- Vista (All years)
