You deserve healthier water in every aspect of your daily life, not just the drinking water. The RCCQ-RS replacement cartridge for the Restore dechlorinating shower filter provides a long lasting solution to the problems associated with exposure to excessive amounts of chlorine. Its specially-formulated KDF®-55 filter media effectively removes 90% or more of chlorine from shower water. Once in contact with the KDF®-55, chlorine in the water converts into an environmentally safe and harmless soluble chloride. The RCCQ-RS installs quickly and easily into the Restore. Additional O-rings Included.
