20-Stage Shower Filter with 5 Replacement Cartridges — Over 2 Years of Filtration
Stock up and save. This bundle includes one 20-stage filter housing plus five replacement cartridges, giving you over two years of filtration at the recommended 3–6 month replacement cycle.
How the Filtration Works
Each 20-stage cartridge combines KDF 55 media, high-quality activated carbon, and calcium sulfite which helps to reduce chlorine, chloramine, heavy metals, and sediment. KDF 55 works through a copper-zinc redox process that converts free chlorine into harmless chloride. Activated carbon adsorbs organic compounds and helps reduce odor.
Works With Hard Water & Well Water
If you're in a hard water area or on well water, this filter helps reduce the contaminants that can leave skin feeling dry and hair looking dull. It complements whole-home water treatment systems by providing an additional layer of filtration at the point of use.
Easy Installation, Universal Fit
Threads onto any standard ½" shower arm and works with wall-mounted, handheld, rainfall, and combo shower heads. No tools required — hand-tighten with included plumber's tape. Maintains consistent water pressure through the filtration stages.
What's Included
• 20-stage filter housing with cartridge installed
• 5 × replacement filter cartridges
• Plumber's tape
Replacement Schedule
Each cartridge lasts approximately 3–6 months depending on water quality and usage. Allow water to run through for 5–10 minutes on first use to flush any carbon dust.
