• Importance in Water Purification: The quartz sleeve helps to protect the UV lamp inside the tube of the water Filtration systems, allowing UV light to penetrate the water without interruption.
• 100% Chemical-Free: Ultraviolet-C is a chemical-free method of filtration and does not affect taste, color, odor, or pH levels of the water, ensuring continuous purification around the clock.
• Cost Effective & Easy Maintenance: Quartz sleeves are easy to clean and replace, last a long time, and require minimal maintenance. If the quartz tube becomes murky and hard to see through, it is recommended to clean or replace it for optimal continuous purification.
