One of the most important additions to nontoxic living- your showerhead! This filter helps purify shower water to be gentler on your hair, skin, and nails and prevent absorption of toxins into your skin. Filtered with a high concentration of 86% KDF-55 (recognized for its water-cleansing properties, AKA clean water’s BFF) that works with Calcium Sulfite to help reduce chlorine & impurities. Helps neutralize odors & balance water pH levels*, which may support healthier hair & skin. Transforms your shower into the ultimate spa-like experience. Doesn’t compromise your shower’s existing water pressure, so you can still enjoy your washtime ritual. Designed to attach to most standard US ½” (1.27cm) shower pipe threads for use with fixed, rain, and handheld shower heads.* Easy-to-install, twist-on design with hassle-free filter cartridge replacement (no need to call the plumber!) Includes everything you need for installation: one filter, one filter cartridge, wrench & plumber’s tape. For safe & secure installation, ensure your shower head has a weight capacity of 15 lbs.
