Would you like to have healthier, younger looking skin and softer more manageable hair? Or maybe you would like less fading of your color treated hair. With a CQ-1000-DS shower filter from Rainshowr you can have all of that, Rainshowr uses KDF to remove chlorine from your shower water to eliminate those problems, and you also won't be inhaling toxic chlorine fumes. The CQ-1000-DS shower filters will remove 90% or more of chlorine they are NSF/ANSI certified for reduction of free chlorine. We recommend you replace the cartridges every 6 to 9 months for a family of 3 to 4. Rainshowr also has quartz crystals to energize your shower water by reducing water surface tension which will increase sudsing and lathering of soaps and shampoos.
