QT Makes Changing Filters Quick, Easy & Sanitary!
QT water filter systems use a “Qwik-Twist” (QT) cartridge. Simply discard the cartridge and “twist” in the replacement

QT Advantages:
- In-store staff can easily change filter cartridges.
- No need to empty water from a sump or clean and sanitize before replacing the filter.
- OptiPure Multi-Point systems use all QT cartridges from beginning to end!
- Filter replacement is quick and simple. Turn off the water, a quarter-turn to the left, pull down and remove the cartridge. Line up the insert arrows, push the new cartridge into the filter head, a quarter-turn to the right and the filter is replaced. It’s that simple.
FX Water Filter Systems offer Exceptional Performance and Great Value!

FX Advantages:
- Replacement cartridge cost-per-gallon is much less than with quick-change filters.
- Generates less waste than metal or plastic quick-change filters. Only the drop-in media is discarded — more environmentally-friendly choice.
- Based on performance, system cost is typically less than quick-change style systems.
- Lower cost replacement cartridges compared to the quick-change cartridges.
