4-in-1 Remineralization Filter Cartridge, 2″x10″, 1/4″ and 3/8″ Quick Connect (SKU# MINERAL4IN1)

Description 4-in-1 Remineralization Filter Cartridge This post-filter is designed to slightly raise pH levels to approximately 7.5–8.2 and restore essential minerals removed during the reverse osmosis process. It contains four types of high-quality natural mineral media: Tourmaline stone Bioceramic infrared media Maifan stone Alkaline and calcite blend These elements work together to enrich purified water with dissolved oxygen and release vital minerals such as Calcium, Magnesium, Sodium, Potassium (K), Phosphorus (P), Zinc (Zn) and more—helping to rebalance and revitalize your drinking water. Tourmaline Media Tourmaline, also known as the “Magic Stone,” is a semi-precious mineral renowned for its detoxification and health benefits. It helps relieve stress, improve circulation, boost immunity, and enhance mental clarity. It also emits Far Infrared Rays (FIR) and negative ions, which gently heal, stimulate, and detox the body. FIR waves can penetrate deeply into the body, reaching tissue, muscles, and bones. According to Dr. M. Terman of Columbia University, negative ions—like those produced by tourmaline—can significantly improve mood and energy levels, with studies showing benefits comparable to antidepressants, but without side effects. Additional benefits include:– Reduction of water molecule clustering– Activation of water molecules, enhancing hydration– Improved oxygen levels in the body– Release of over 15 trace minerals, including SiO₂, K₂O, CaO, Na₂O, and MgO Learn more about the benefits of Tourmaline → Maifan Stone Media Maifan stone is highly absorbent and effective at removing heavy metals and contaminants. It also replenishes the water with essential minerals like Calcium, Iron, Zinc, Magnesium, and Selenium. Bioceramic Infrared Media A powerful source of Far Infrared Rays (FIR) and negative ions, this media helps improve circulation, boost cellular activity, and promote natural detoxification. Alkaline & Calcite Mineral Media This blend helps neutralize acidity and gently boosts the pH level while releasing additional minerals for taste and health support.
