How Reverse Osmosis Works
Reverse osmosis is a water purification process that uses a semipermeable membrane to remove dissolved solids, ions, and other contaminants from water. Water is forced through the membrane at high pressure, leaving behind impurities while pure water passes through to your tap.
The result is water that is 99% free of contaminants including minerals, salts, bacteria, viruses, and chemical compounds. RO systems are especially valuable in Arizona, where municipal and well water often contains elevated levels of minerals and contaminants.
Contaminant Removal
Removes dissolved minerals, salts, bacteria, viruses, and chemicals from your water supply.
Space-Efficient
Compact systems fit neatly under your kitchen sink, providing pure water directly at your tap.
Reliable Performance
Properly maintained RO systems provide years of pure water with minimal maintenance required.
What RO Systems Remove
Reverse osmosis is highly effective against a wide range of contaminants.
| Contaminant Type | RO Removal Rate | Health/Property Impact |
|---|---|---|
| Arsenic | 95-99% | Cancer, organ damage risk |
| Lead | 95%+ | Neurological damage, especially children |
| Fluoride | 95%+ | Dental fluorosis, bone effects at high levels |
| Nitrates | 99% | Methemoglobinemia (blue baby syndrome) |
| Calcium & Magnesium | 95%+ | Hard water, appliance scale buildup |
| Chlorine & Chloramines | 99% | Bad taste, odor, disinfection byproducts |
| Bacteria & Viruses | 99.99% | Gastrointestinal illness risk |
| Pesticides | 95-99% | Hormonal disruption, neurological effects |
| PFAS (forever chemicals) | 90-99% | Liver damage, thyroid disease, kidney disease |

Running a business?
Espresso bars, restaurants, breweries, salons, and offices need RO sized to equipment demand, not household use. See Commercial Reverse Osmosis in Prescott — point-of-use from $829, custom systems quoted from your water test.
This price applies in Prescott, Prescott Valley, Chino Valley, Dewey-Humboldt, Sedona, Cottonwood, the Verde Valley, Flagstaff and the Phoenix metro — it is not a Prescott-only rate. Outside those areas, call and you’ll get a straight yes or no on whether the job works.
Reverse Osmosis Questions
Yes — reverse osmosis water is among the safest drinking water available. A properly installed RO system removes 95–99% of dissolved contaminants including arsenic, lead, fluoride, nitrates, PFAS, chlorine, and bacteria. RO does remove trace minerals like calcium and magnesium, but the World Health Organization confirms people get the vast majority of these from food, not water.
An under-sink reverse osmosis system is a flat rate: $829 for The Kitten 4-stage or $1,250 for The Ocelot 5-stage, installed (a new faucet hole, if needed, is $50). Whole-home reverse osmosis is $14,999.99 flat anywhere in Arizona — The Lion Package: 2,000-gallon-per-day Charger AEC-2000, 200-gallon storage tank, delivery pump, and first-year maintenance included. Aqua Cat sizes the system from a $185 lab water test.
RO pre-filters (sediment and carbon) typically need replacement every 6 to 12 months. The RO membrane itself lasts 2 to 5 years depending on feed water quality. Post-filters last 1 to 2 years. Aqua Cat sets a maintenance schedule for every install and offers reminder service so the system never under-performs.
Older RO systems wasted 4 gallons for every 1 gallon of pure water. Modern systems with high-efficiency membranes and permeate pumps now produce 1 gallon of pure water for every 1 to 3 gallons of brine. The brine line drains to your home's wastewater. For an average Prescott household, that's roughly $2 to $4 per month in extra water cost.
Yes. RO water improves the taste of coffee, tea, soups, and rice because there are no off-flavors from chlorine, sulfur, or hardness minerals. Most homeowners run a line from the under-sink RO unit to the refrigerator's ice maker and water dispenser as well. Whole-home RO covers every tap, but is overkill if your only goal is drinking and cooking water.
Yes — reverse osmosis is one of the most effective methods for removing arsenic, PFAS, lead, and nitrates from well water. RO membranes reject arsenic V at 95+% and PFAS at 90–99% depending on the compound. For homes with high arsenic levels, Aqua Cat often pairs RO with a dedicated arsenic-removal cartridge upstream for redundancy. See our arsenic removal page for details.
Aqua Cat installs under-sink and whole-home reverse osmosis across Prescott, Prescott Valley, Chino Valley, Dewey-Humboldt, Sedona, Cottonwood and the Phoenix area. A standard under-sink RO install takes about two hours, including the faucet and the drain saddle, and you get the owner doing the work rather than a subcontracted installer. RO is the most thorough option for drinking water — it is what removes arsenic and PFAS down to trace levels. It does not soften the water in the rest of the house, so homes with hard Yavapai County water usually pair RO at the kitchen sink with a whole-home softener.
They’re the same Charger HydroSplash platform — 75 GPD twist-off membrane, same tank, same faucet, same 1:1 water economy. The Ocelot adds a fifth stage: alkaline remineralization. RO water is extremely pure, which also makes it slightly acidic and flat-tasting to some palates. The alkaline stage restores minerals like calcium and magnesium and raises the pH, so the water drinks smoother. If you love the taste of bottled alkaline water, that’s the Ocelot at $1,250. If you just want clean, great-tasting water at the best price, the Kitten at $829 is the workhorse.
The manufacturer’s schedule is every 6–12 months for the sediment/carbon modules — closer to 6 if your water runs more than 1 ppm chlorine, which we measure during the free check. The HydroSplash uses proprietary twist-off cartridges with quick-connect o-ring seals, so a change takes about a minute per cartridge: no tools, no wrestling with housings, no open water contact. The membrane assembly itself is also twist-off. If you’d rather never think about it, Aqua Cat offers flat-priced filter service.
