WaterGenie Reverse Osmosis Filter System

Pure Water, Starting at the Source

Clean Water Shouldn't Be Complicated.

 A premium 5-stage reverse osmosis system that fits under your sink, requires no electricity, and makes filter changes something you'll actually do.

Product Features: 

You shouldn't have to think twice about your drinking water. The WaterGenie RO System is designed for exactly that — pure, great-tasting water on tap, without the maintenance headaches that come with most under-sink filters.

Five stages of filtration, built to premium standards, quietly doing their job beneath your sink. Dissolved solids, heavy metals, chlorine, microscopic particles down to 0.0001 microns — gone, before the water ever reaches your glass.

The part that surprises most people? Changing the filters takes seconds, not a Saturday afternoon. The twist-and-turn cartridge design means no housing wrenches, no spills, no calling someone for help. Just twist out, twist in, done.

Already have a WaterGenie sparkling water system? This pairs perfectly with it — so the water going into your machine is as clean as what's coming out.

Why It Stands Out:

• True 5-stage purification — tackles sediment, chlorine, chemical odors, dissolved solids, heavy metals, and more
• Tool-free filter changes — encapsulated twist-and-turn cartridges mean no wrenches, no mess, no hassle
• No electricity required — fully mechanical, runs on standard household water pressure alone
• Compact under-sink footprint — modular manifold design fits in tight cabinet spaces
• NSF-approved pressure tank — 3.2-gallon storage tank keeps purified water ready when you need it
• Made in Taiwan — manufactured to exacting standards with food-grade components throughout

How It Works — The 5 Stages:

Stage 1 — Sediment Filter (ST-05) A 5-micron spun polypropylene filter captures sand, dirt, scale, and larger suspended particles before they reach the more sensitive stages downstream.

Stage 2 — Granular Activated Carbon (ST-33) Activated carbon adsorbs chlorine, organic compounds, and the volatile elements responsible for bad taste and odor.

Stage 3 — Carbon Block Filter (ST-CTO) A dense carbon block delivers a final round of chlorine removal, protecting the RO membrane from chemical degradation and extending its lifespan.

Stage 4 — RO Membrane (ST-RO50) The heart of the system. A semi-permeable membrane filters contaminants down to 0.0001 microns — removing dissolved solids, heavy metals, and micro-contaminants that no standard filter can touch.

Stage 5 — Post-Carbon Polish (ST-34) An inline carbon polish stage fine-tunes the final taste right before the water reaches your faucet. Clean water that actually tastes clean.
