Reverse Osmosis Water Filtration Systems

The Gold Standard for Drinking Water Purity

When it comes to achieving the cleanest, purest drinking water possible, few systems can match the performance of Reverse Osmosis (RO) filtration. Unlike standard point-of-use filters that reduce chlorine, sediment, and some contaminants, RO systems go further—removing up to 99% of dissolved solids, heavy metals, fluoride, arsenic, and other microscopic impurities. With an RO system installed in your home or business, every glass of water is not only refreshing but also exceptionally safe for cooking, drinking, and even making coffee or tea.

How Reverse Osmosis Works

Reverse Osmosis uses a multi-stage filtration process that forces water through a semipermeable membrane. This process separates contaminants from the water at a molecular level, ensuring only clean water passes through. Most RO systems include multiple filters (sediment, carbon, and the RO membrane) to maximize performance.

The result? Crystal-clear, better-tasting water that rivals—or even surpasses—bottled water, right from your tap.

Benefits of a Reverse Osmosis System

  • Superior contaminant removal – Effectively reduces heavy metals, pesticides, nitrates, fluoride, arsenic, and more.
  • Improved taste & odor – Eliminates unpleasant smells and chemical aftertastes.
  • Healthier hydration & cooking – Enjoy safe, filtered water for drinking, making baby formula, and preparing meals.
  • Cost savings – Cut down on bottled water purchases with an endless supply of purified water at home.
  • Compact, point-of-use installation – Typically installed under the sink with a dedicated faucet for easy access.

Quick and courteous response, plus my 10 year old service records from a company Castleworks acquired! Salvador, the technician, was personable, worked quickly, explained paperwork, options, and maintenance recommendations, and left no waste.

This is our second huge projects with Castleworks. Justin went above & beyond, not only making what could have been a huge issue. He figured out the best way to do do with a very minimal amount of holes in walls. He did the work quickly & despite the very small holes needed to connect the pipes, he made it all look like a work of art. I highly recommend recommend the company for any plumbing needs & a special shout out to Justin

I would rate my experience with Christopher Beauvoir's installation of a new water heater as a "5". He was extremely professional and straight-forward about the entire process. Explained teh issues with my old water heater, and installed the new one quickly and efficiently. I would not hesitate to recommend Castle Works to my associates if and when they need that kind of service. thanks again for solving my hot water issues!

CastleWorks does excellent work. Christopher Beauvoir showed up on time, was very knowledgeable, and did an excellent job replacing our old water heater in the garage. They use Bradford White water heaters which are really good. Very happy with the job, thank you!

CastleWorks’ technician, Christopher Beauvoir, showed up on time and quickly diagnosed the problem with the Grundfos circulation pump on our tankless water heater. He also discovered several faulty valves that had deteriorated over the years. Christopher replaced the failing pump and valves and was on his way in short order.

RO Systems vs. Other Drinking Water Filters

While faucet-mounted and under-sink carbon filters do a great job improving taste and reducing chlorine, only RO systems address dissolved solids and a wider range of contaminants. If your household is particularly concerned about fluoride, heavy metals, or other microscopic pollutants, Reverse Osmosis is the most effective solution available.
