The unit arrives pre-filled with 9.5 liters of mixed-bed resin inside a robust 9\"x20\" FRP tank, includes hose fittings, a TDS pen for testing, and a simple bypass valve so you only use DI water where it matters.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the AKM system prevent water spots?\u003c\/h3\u003e\n\u003cp\u003eThe system deionizes tap water by exchanging mineral ions in the resin, producing essentially pure water for the final rinse.
