Check the listing for details. 5-in-1 Re-Mineralization Inline Water Filter, 3/8" & 1/4" QC for Reverse Osmosis. Color: White, Condition: New. Listed at 29.50 USD. The 5-in-1 Remineralization Filter Cartridge is engineered to improve your water’s quality by slightly raising the pH to a healthy alkaline range of 7.5 to 8.2. This filter incorporates five types of mineral media to replenish essential minerals and oxygen levels in water, ensuring a healthy balance after reverse osmosis (RO) filtration. This unique combination releases crucial minerals like calcium, magnesium, sodium, potassium, phosphorus, and zinc, contributing to your overall well-being. Additionally, it introduces dissolved oxygen, enhancing water’s hydration capabilities. Key Features:pH Balance: Slightly raises water pH to an alkaline range of 7.5–8.2 for healthier, more refreshing drinking water.5 Mineral Media Combination: Includes tourmaline stone, bioceramic infrared media, maifan stone, calcite/corosex media, and alkaline/mineral media for comprehensive mineral restoration.Essential Mineral Release: Reintroduces calcium, magnesium, sodium, potassium, phosphorus, zinc, and other essential minerals needed for optimal health.Enhanced Oxygen Levels: Increases dissolved oxygen for superior hydration.Perfect for Post-RO Systems: Restores vital minerals after reverse osmosis filtration, creating healthier and more balanced water. 5 Mineral Media Benefits:Tourmaline Media: Known as the "Magic Stone," tourmaline supports detoxification, relieves stress, enhances mental alertness, and improves circulation. It emits Far Infrared Rays (FIR) and negative ions, which gently stimulate the body, improving overall health.Maifan Stone Media: This natural stone is strongly absorptive, helping remove heavy metals and contaminants from the water, while releasing beneficial minerals like calcium, iron, zinc, magnesium, and selenium.Bioceramic Infrared Media: Provides a powerful source of negative ions and FIR, enhancing the overall quality of your drinking water by stimulating mineral content.Alkaline/Mineral Media: Designed to release extra minerals, further enhancing water’s alkalinity and delivering health benefits through the re-mineralization process.Calcite/Corosex Media: This combination works effectively to raise water pH, neutralizing acidic water and preventing corrosion in plumbing, while simultaneously restoring healthy minerals. Upgrade your water system with this advanced 5-in-1 remineralization filter cartridge, designed to bring out the best in your drinking water by restoring its mineral balance and increasing pH for healthier hydration. Quick Connect Fittings: Includes 3/8" and 1/4" quick connect fittings for easy installation into most RO systemsTubing and extra clips included
