THE CLEAN WATER BUYER’S GUIDE
Why Reverse Osmosis Wins for Cleanliness & Affordability
By Choice Water Systems
Why Reverse Osmosis?
Reverse Osmosis (RO) is one of the most effective ways to purify drinking water. It forces water through an ultra‑fine membrane that removes contaminants other systems simply can’t touch — giving you clean, crisp, great‑tasting water right at your tap.
Why We Install Only 5‑Stage RO Systems
At Choice Water Systems, we believe your home deserves the best. That’s why we install only 5‑stage RO systems, delivering:
Cleaner, better‑tasting water
Deeper contaminant removal
Longer membrane life
More reliable performance over time
A 5‑stage system consistently outperforms 3‑ and 4‑stage units in purity, taste, and long‑term durability.
What’s Inside a 5‑Stage RO System
Stage 1 – Sediment Filtration
Removes: sand, rust, dirt, silt Protects the system by trapping particles down to 5 microns.
Stage 2 – Granular Activated Carbon (GAC)
Reduces: chlorine, chemicals, organic compounds Improves taste and protects the membrane.
Stage 3 – Carbon Block Filtration
Provides deeper chemical reduction and removes pesticides, herbicides, VOCs.
Stage 4 – RO Membrane
Removes:
Heavy metals (95%–99%)
Microplastics (~99%)
Bacteria & viruses (~99%)
Fluoride, arsenic, nitrates (90%–95%)
Dissolved solids (90%–99%)
Stage 5 – Polishing Carbon Filter
Final taste‑enhancing stage that removes residual odors and ensures crisp, clean flavor.
Why a 5‑Stage System Is Superior
Cleaner, Better‑Tasting Water
Two carbon stages remove more chemicals before water reaches the membrane.
Longer Membrane Life
Extra carbon protection means fewer replacements and lower long‑term cost.
Higher Purity Levels
More filtration stages = more contaminant reduction and lower TDS.
Better for Hard Water Homes
Additional pre‑filtration helps prevent scaling and fouling.
Filter Replacement Schedule
Sediment filter: every 6–12 months
Carbon filters (2 stages): every 6–12 months
RO membrane: every 2–3 years
Polishing carbon filter: every 12 months
System Lifespan
With proper maintenance, a 5‑stage RO system lasts 10–15 years and maintains high performance throughout its life.
Common RO Issues (and How a 5‑Stage System Helps)
Clogged filters → extra pre‑filtration reduces strain
Bad taste → polishing filter ensures clean flavor
Membrane wear → dual carbon stages protect it
Low pressure → high‑quality components maintain flow
