Five dedicated filtration stages work together for comprehensive purification: (1) Sediment Cartridge, (2) GAC Filter (Granulated Activated Carbon), (3) ACB Filter (Activated Carbon Block), (4) Osmotic Membrane, (5) Reverse Osmosis post polishing filter. Each stage targets a different category of contaminant for complete, layered protection.

The RoyalSoft 5-Stage Reverse Osmosis system includes everything you need for a complete installation: Including filter housing, 5 stage filters and a 3-gallon R.O. Holding Tank.

Product Details

Five Stages of Pure Protection

Stages 1–3: Pre-Filtration
Three pre-filter stages that work in sequence to remove sediment, chlorine, and other particulates before water reaches the membrane, protecting the membrane and extending its service life. Includes (1) Sediment Cartridge, (2) GAC Filter (Granulated Activated Carbon), (3) ACB Filter (Activated Carbon Block)
Stage 4: Osmotic Membrane (75 GPD)
The heart of the system — a high-performance 75 gallon-per-day osmotic membrane that filters water at the molecular level, removing up to 99% of dissolved contaminants including lead, mercury, arsenic, fluoride, nitrates, and dissolved salts that other filtration methods cannot capture.
Stage 5: Reverse Osmosis Post Polishing Filter
A post-membrane activated carbon stage provides a final polishing step, removing any remaining taste and odor compounds and ensuring the water stored in your holding tank stays fresh and clean until it reaches your glass.

What does a reverse osmosis system remove from drinking water?

Reverse osmosis removes up to 99% of over 140 contaminants — including lead, mercury, arsenic, fluoride, chlorine, nitrates, pesticides, dissolved salts, pharmaceutical residues, and asbestos. It works at the molecular level, which is far more thorough than conventional carbon or sediment filters alone.

Is reverse osmosis water safe to drink?

Yes — the RoyalSoft 5-Stage Reverse Osmosis System delivers water that is both safe and great-tasting. Many consider R.O. water purer than most bottled water brands.

How often do the filters need to be replaced?

Pre and post-filter cartridges are typically replaced every 6–12 months, depending on water quality and usage. The osmotic membrane generally lasts 2–3 years. Your Clean Water Pro technician can manage all filter replacements for you and will advise you on the optimal schedule for your specific water.

Can I use R.O. water for cooking and beverages?

Absolutely. In fact, many people notice a dramatic improvement in the taste of coffee, tea, soups, and anything else made with water after installing a reverse osmosis system. Purer water allows the natural flavors of food and beverages to shine through without the interference of chlorine or mineral taste.

Does the RoyalSoft system remove fluoride?

Yes. The reverse osmosis membrane is highly effective at removing fluoride — unlike carbon filters and water softeners, which do not remove fluoride. If fluoride reduction is a priority for your household, the RoyalSoft 5-Stage Reverse Osmosis System is one of the most effective options available.

How does R.O. compare to bottled water?

The RoyalSoft 5-Stage Reverse Osmosis System produces water that meets or exceeds the purity of most premium bottled water — at a fraction of the cost. The average household can save $500 or more per year by replacing bottled water with an R.O. system, while also eliminating thousands of plastic bottles from landfills annually.
