A: The tank requires 4L of resin, filled just below the tank head threads.

Q: How long will the resin last?
A: It can filter approximately 1,000L of water with an input TDS of 80-100 ppm. Actual lifespan varies based on water quality.

Q: Why doesn’t this model have a carbon pre-filter like larger units?
A: This unit is too small to accommodate a pre-filter housing. A pre-filter is not essential, as this system is designed for occasional use rather than daily professional applications.
