Kinetic Degradation Fluxion (KDF) filters are designed to remove dissolved metals.

• A. True
• B. They remove minerals
• C. False
• D. They remove microbes only

Answer: (A)

Kinetic Degradation Fluxion filters remove dissolved metals by using a copper–zinc alloy media that creates redox reactions as water flows through. The alloy transfers electrons to or from dissolved metal ions in the water, changing their oxidation state and causing them to precipitate or bind to the media. That process pulls metal ions like iron, manganese, lead, and other dissolved metals out of solution, lowering their concentration in the filtered water. This is the primary purpose of KDF media; it’s not designed to remove minerals in general, and it isn’t limited to microbes only. (They may also help reduce chlorine and other contaminants, but metals removal is a defining function.)
