KDF filter media granules

KDF Filter Media Granules

Everyone knows that the health of drinking water is important, but regular household water is no exception. More and more people are beginning to pay attention to the quality of water used for cooking, bathing, and cleaning. After prolonged use, showerheads often accumulate significant scale in their nozzles. Beyond these visible impurities, ordinary showerheads lack a filtration system, allowing harmful substances commonly found in tap water—such as residual chlorine, rust, and sediment—to remain. Additionally, bacteria can gradually grow in the showerhead nozzles. Over time, this can inevitably have adverse effects on the skin.
Especially for women, impurities, bacteria, and residual chlorine in water directly impact skin health. Long-term exposure can cause skin damage and accelerate aging. Therefore, we also need cleaner water for washing our face and bathing. Through filter technology (KDF media), residual chlorine is removed, ensuring the water output is healthy for bathing.

KDF is a high-purity copper-zinc alloy that removes oxidants from water, such as residual chlorine. This process occurs through a redox reaction, or electrochemical reaction, between copper and zinc in water. Because KDF consists of two different metals, copper and zinc, when in contact with water, the copper (with a higher electrochemical potential) acts as the cathode, while the zinc (with a lower potential) acts as the anode. Reduction occurs at the cathode, and oxidation occurs at the anode. In the chlorine removal reaction, the zinc anode loses electrons, releasing a certain number of zinc ions into the solution, while reduction of free chlorine occurs at the copper cathode without dissolving the copper metal. Water and residual chlorine become the final electron acceptors, transforming into hydrogen ions, hydroxide ions, and chloride ions. The overall reaction is as follows: Zn + HOCl + H₂O + 2e⁻ → Zn²⁺ + Cl⁻ + H⁺ + 2OH⁻. The chloride ions in water are harmless to the human body and may even offer some benefits.
Functions:
(1) Remove Residual Chlorine: In certain scenarios, such as with free chlorine, this chemical reaction can convert it into beneficial substances, removing chlorine, trihalomethane byproducts, hydrogen sulfide, and other harmful gases, which are then filtered out in the next layer.
(2) Remove Heavy Metals: KDF55 media can remove up to 98% of water-soluble inorganic heavy metals. Harmful heavy metals like iron, lead, copper, and mercury react and precipitate on the surface of the media, effectively removing them from water.
(3) Inhibit Bacteria: KDF media also controls microorganisms and genuinely has antibacterial effects. The electrolyte environment created by the redox reaction is lethal to certain microbes. The reaction also produces hydroxyl radicals and hydrogen peroxide (H₂O₂), which reduce the activity of other microorganisms.
(4) Prevent Scaling: By creating a unique electrolyte environment that inhibits bacterial growth, it reduces scale formation in places like showerheads and bathtubs. It can even alter calcium molecules in water to prevent scaling.
