Reverse Osmosis Systems Rochester, NY
Reverse osmosis systems force water through a semi-permeable membrane, removing up to 99% of dissolved contaminants including lead, PFAS, chromium-6, fluoride, arsenic, and more.
What Is Reverse Osmosis Systems?
Reverse osmosis (RO) is the most effective water purification technology available for residential use. An RO system pushes water through a semi-permeable membrane with pores so small that virtually all dissolved contaminants are rejected — including lead, PFAS, chromium-6, arsenic, fluoride, nitrates, and total dissolved solids (TDS). Most under-sink RO systems include 3 to 5 stages: a sediment pre-filter, carbon pre-filter, the RO membrane, and a post-filter for taste polishing. The purified water is stored in a small pressurized tank under your sink and dispensed through a dedicated faucet. For families who want the highest level of drinking water purity, reverse osmosis is the gold standard.
How It Works
Most RO systems are installed under the kitchen sink and include multiple filtration stages.
Sediment Pre-Filter (Stage 1)
Removes sand, silt, and particulates that could damage the RO membrane. Typically a 5-micron filter replaced every 6–12 months.
Carbon Pre-Filter (Stage 2)
Activated carbon removes chlorine, which can degrade the RO membrane. Also reduces THMs, VOCs, and improves taste before the water reaches the membrane.
RO Membrane (Stage 3)
The core of the system. Water is forced through a membrane with pores as small as 0.0001 microns — rejecting up to 99% of dissolved contaminants including lead, PFAS, arsenic, chromium-6, fluoride, and more.
Post-Filter & Storage (Stage 4–5)
Purified water passes through a final carbon polishing filter for optimal taste, then is stored in a pressurized tank. Some systems add a remineralization stage to restore beneficial minerals.
Why Rochester Homes Need Reverse Osmosis
With 1 in 3 Rochester water lines containing lead and chromium-6 detected at 3 to 4 times health advocacy guidelines, an RO system at your drinking water tap is the most effective protection for your family. Rochester's water also contains detectable levels of haloacetic acids and trihalomethanes from chlorine disinfection — all effectively removed by reverse osmosis. For families with lead service lines who can't wait for the city's 2030 replacement deadline, RO provides immediate, verified protection.
Key Benefits

Under-sink RO systems are the most popular and cost-effective option for drinking water protection. Whole-house RO is available for families wanting purified water at every tap but requires more complex installation and higher operating costs. All installations include the dedicated faucet, storage tank, and connection to your cold water line.
Frequently Asked Questions
Does reverse osmosis waste water?
Traditional RO systems produce 3 to 4 gallons of wastewater per gallon of purified water. We install high-efficiency models with a 1:1 ratio (1 gallon waste per gallon purified), which is significantly more water-efficient. The wastewater goes to drain and is comparable to running a faucet for a few extra minutes per day.
Does RO remove beneficial minerals?
Yes, RO removes virtually everything from the water, including minerals like calcium and magnesium. However, most of your daily mineral intake comes from food, not water. If you prefer mineralized water, we offer systems with a remineralization stage that adds back calcium and magnesium after purification.
How often do RO filters need to be replaced?
Pre-filters and post-filters are typically replaced every 6 to 12 months. The RO membrane lasts 2 to 3 years. We offer annual maintenance plans that include all filter replacements and system inspection.
Can I connect an RO system to my refrigerator ice maker?
Yes. We routinely connect RO systems to refrigerator ice makers and water dispensers. This ensures your ice and cold water are also purified. It requires a small additional line during installation.
