A point-of-use reverse osmosis (RO) system is a water filtration device that is connected to a single fixture (e.g., under the kitchen sink) and uses the process of RO to remove contaminants from the water supplied to that fixture. RO is the process by which pressure forces water through a semi-permeable membrane, creating a stream of treated water, called “permeate,” and a stream of reject water called “concentrate” or “brine.” These systems can potentially remove water contaminants such as lead, volatile organic compounds (VOCs), PFAS, arsenic, bacteria, and viruses. Point-of-use RO systems are typically installed in residential settings but can also be found in commercial office spaces or kitchens.

Treat With Efficiency
While RO systems can improve water quality, these systems can also generate a significant amount of water waste to operate. For example, a typical point-of-use RO system will generate five gallons or more of reject water for every gallon of treated water produced. Some inefficient units will generate up to 10 gallons of reject water for every gallon of treated water produced. In contrast, point-of-use RO systems that earn the WaterSense label must demonstrate that they send just 2.3 gallons of water or less down the drain for every gallon of treated water they produce.
All products bearing the WaterSense label are independently certified to ensure they meet EPA criteria for efficiency and performance. The WaterSense specification for point-of-use RO systems ensures that labeled RO systems are just as effective at providing the high-quality treated water consumers expect from these products. For more information on RO systems, including how they work and how to select an RO system that is right for you, view this WaterSense report, Treating Water With Less Waste (pdf) .
While the water provided by public water suppliers in the United States is some of the safest in the world, there are times when consumers may want to employ additional treatment technology to ensure safety of well water or publicly-supplied water. Due to the water-intensive nature of RO, WaterSense does not intend to promote the installation of RO systems for all applications or encourage their use over other water treatment technologies that do not waste as much water (e.g., filtration systems). In some cases, other treatment methods that use little or no water, such as filtration, are sufficient to meet consumer treatment needs. For more information, read the WaterSense Guide to Selecting Water Treatment Systems (pdf).
WaterSense Savings
For consumers who are planning to replace their reverse osmosis system at the point of water use, selecting a WaterSense labeled model will reduce water use on average by more than 3,100 gallons of water per year compared to the water usage of a typical point-of-use RO system. This translates to a savings of 47,000 gallons over the lifetime of the system.
If all point-of-use RO systems sold in the United States were WaterSense labeled, we could save more than 3.1 billion gallons of water across the country annually, which is equivalent to the annual household water needs of nearly 41,000 American homes.

Performance
As part of the WaterSense specification development process, EPA examined key performance metrics to ensure consumer satisfaction. EPA also considered the impact of reducing water waste on RO system performance.
All WaterSense labeled point-of-use RO systems are independently certified to meet performance criteria to ensure user satisfaction and health and safety. Performance criteria address the following areas:
See the Performance Overview for more information on how WaterSense assessed performance when developing the specification.
Specification
In November , EPA released the WaterSense Specification for Point-of-Use Reverse Osmosis Systems.
EPA hosted a meeting for manufacturers to discuss the final specification and process for earning the WaterSense label for RO systems on December 17, . The presentation and recording are available below.

In today’s business environment, water quality is a critical concern for many industries. From restaurants and hotels to manufacturing plants and healthcare facilities, access to clean, purified water is essential. Reverse osmosis (RO) systems have emerged as a reliable solution for commercial water purification. But what exactly is reverse osmosis, and why is it such a popular choice for businesses?
This blog dives into the details of reverse osmosis systems, providing a comprehensive explanation of how they work, their benefits, and how they cater to the needs of various industries.
Reverse osmosis is a water purification process that removes contaminants from water by pushing it through a semipermeable membrane. This process effectively eliminates impurities such as salts, minerals, and harmful substances, leaving water that is clean and safe for various applications.
To understand reverse osmosis explained in simple terms, think of it as a fine filter that separates clean water from impurities at the molecular level. The process relies on pressure to force water through the membrane, which traps contaminants while allowing purified water to pass through.
A commercial reverse osmosis system comprises several critical components that work together to deliver purified water:
Understanding these components helps businesses choose the right system tailored to their specific needs.
To better grasp the benefits of commercial water purification through reverse osmosis, it’s essential to understand how the process functions step-by-step:
The simplicity and efficiency of this process make reverse osmosis systems a cornerstone of commercial water purification.
Why should businesses invest in reverse osmosis systems? Here are some key benefits:
Reverse osmosis systems effectively remove up to 99% of impurities, including harmful chemicals, bacteria, and dissolved salts. This level of purification ensures the water meets stringent quality standards required in industries like healthcare and food services.
While the initial investment in a reverse osmosis system may seem significant, the long-term savings are substantial. Businesses save on bottled water costs, equipment maintenance, and potential damage caused by poor water quality.

Commercial water purification using reverse osmosis reduces reliance on single-use plastic bottles, lowering the business’s environmental footprint. Additionally, some advanced systems recycle wastewater, further enhancing sustainability.
Poor water quality can damage equipment over time. Reverse osmosis systems prevent scale buildup and corrosion, extending the lifespan of machinery like boilers, dishwashers, and cooling systems.
Different industries have unique requirements for water quality. Here’s how reverse osmosis systems cater to these diverse needs:
Hotels and restaurants depend on clean water for cooking, cleaning, and guest services. Reverse osmosis systems ensure water used in food preparation is free from contaminants, enhancing taste and safety.
Industries like electronics and pharmaceuticals require ultra-pure water for production processes. Reverse osmosis systems deliver the necessary quality, ensuring products meet rigorous standards.
Hospitals and clinics use purified water for patient care, sterilization, and lab work. RO systems provide a reliable source of contaminant-free water critical for these applications.
In agriculture, water quality directly impacts crop yield and livestock health. Reverse osmosis systems help farmers remove harmful salts and chemicals, ensuring better outcomes.
For corporate environments, providing employees with clean drinking water is a priority. Installing reverse osmosis systems demonstrates a commitment to employee health and wellbeing.
Selecting the ideal commercial reverse osmosis system involves evaluating several factors:
Understanding the composition of your water supply is the first step. A professional water test will reveal the types and concentrations of impurities that need to be addressed.
Consider how much purified water your business requires daily. Systems are available in various capacities, from small-scale units to large industrial setups.
Regular maintenance ensures optimal performance. Choose a system with easy-to-replace filters and readily available spare parts.
While reverse osmosis systems vary in price, balancing upfront costs with long-term savings is crucial for making the right decision.
