If you want the absolute best for your home, your appliances, and your family, this is the system that sets the standard.
Why Rain King Is the Elite Choice
This system combines four professional‑grade filtration layers into one seamless unit, each designed to solve a major water problem:
Stage 1 — Activated Carbon
Removes chlorine, odors, discoloration, chemical tastes, and organic contaminants for cleaner, fresher water throughout your home.
Stage 2 — KDF‑55 (Extended Layer)
Reduces up to 99% of free chlorine and heavy metals like lead and mercury. Inhibits bacterial growth and protects downstream media for longer life.
Stage 3 — 10% Cross‑Linked Softening Resin
High‑capacity resin beads remove hardness minerals (calcium & magnesium) through ion exchange, delivering softer water, smoother skin, and longer‑lasting appliances.
Stage 4 — Garnet Polishing Layer
A final ultra‑dense filtration stage that removes fine sediment and ensures your water is crystal clear before it reaches your faucets.
