Reverse Osmosis Systems
Not all water is created equal — and if your tap water tastes metallic, smells odd, or leaves residue in your glass, it might be time to upgrade.
At Onyx Plumbing & Gas, we install reverse osmosis (RO) filtration systems that give your family direct access to ultra-clean, great-tasting drinking water right from your kitchen sink. Whether you’re dealing with poor water quality from a municipal supply or you just want cleaner, better water for your home, our team delivers smart water filter solutions that work — and last!
Tired of lugging bottled water home or relying on fridge filters that never quite do the job? RO systems are built to deliver five-stage filtration — reducing impurities down to the molecular level.
The result is safer, better-tasting water for drinking, cooking, coffee, tea, baby formula, and more.
At Onyx Plumbing & Gas, we don’t just install a system and call it done — we take the time to size your filter to your home’s water usage, ensure it’s installed cleanly and securely, and walk you through how to maintain it properly.
Our Minnesota-Licensed Master Plumbers install with precision and back it up with a full 1-year labor warranty. Schedule a consultation with our plumbing professionals today!
The benefits of reverse osmosis water filtration go far beyond just taste. These under-sink systems are a long-term solution for households that want healthier, more reliable water without the expense (or waste) of single-use plastic bottles.
Here’s why more homeowners in St. Louis Park and the west metro are making the switch:
Cloudy, rusty, or discolored water isn’t just unpleasant! It can signal underlying contaminants.
RO systems remove sediment, bacteria, and dissolved solids, giving your water a clean, clear look and feel from the first pour.
No more chlorine aftertaste or sulfur smell.
Reverse osmosis filtration eliminates the impurities responsible for funky odors and flavors, so your drinking water is fresh, crisp, and completely odor-free.
Ditch the bottled water habit!
A professionally installed RO system pays for itself quickly by cutting down on grocery bills and eliminating the need for disposable filters and pitchers that never last.
Every glass you fill at your sink is one less plastic bottle in a landfill.
With a reverse osmosis filter, you reduce your household’s environmental impact without sacrificing convenience or quality.
