The Brondell Circle Reverse Osmosis Water Filtration System is a smarter, more modern take on an under sink RO system, consisting of an all-in-one unit and sleek designer faucet. With four separate water filtration stages, this system fits easily in the space beneath a kitchen sink, and is simple to install and maintain.
Thanks to its smart valve, the Brondell Circle reverse osmosis water filtering system eliminates the back pressure that causes many RO systems to work inefficiently, allowing for less water wastage and a faster tank refill for ultimate convenience.
This water filtration unit comes with a designer faucet that needs to be installed in place of the user’s standard kitchen sink faucet. With a built-in LED filter change indicator, the faucet can remind a user when it’s time to replace a filter in the system.
6 liter storage tank
For holding filtered water before it is delivered to the faucet, this RO system has a 6 liter storage tank that can fill entirely at twice the speed of a standard RO filtration system. The tank is built into the main body of the unit for a more compact design.
The unique feature of this RO system is its smart valve, which prevents the backflow of water that has passed through the semi-permeable membrane. Backflow commonly slows down the reverse osmosis process in standard systems, and this system’s smart valve enables speedier and more efficient water filtration.
Working in tandem with the smart valve for maximum RO efficiency, this unit’s flexible reservoir expands and contracts to provide more consistent water flow rates. This keeps the water pressure at a steady level and again prevents backflow through the RO membrane.
The sediment filter in this system provides the first stage of water filtration before it can pass any further into the unit. The role of the sediment filter is to remove larger particles that might damage the system and block the filters during reverse osmosis.
Pre-carbon plus filter
Essential for removing unpleasant odors, taste and cloudiness from chlorine and chloramines, water passes through this unit’s pre-carbon plus filter before making it to the RO membrane filter.
RO membrane filter
At the center of this RO system is the semi-permeable membrane, where the reverse osmosis process takes place. Water passes through the membrane under pressure, trapping contaminants and impurities like lead, copper, ammonia, fluoride, and much more.
Post carbon block filter
Between the water storage tank and the faucet sits the post carbon block filter, which gives water one final treatment before drinking. Any odors, cloudiness or tastes that water might have picked up from the storage tank is removed for clearer, more enjoyable pure water.
With its smart valve and flexible reservoir, the Brondell Circle Reverse Osmosis Water Filtration System is one of the most efficient reverse osmosis filtration solutions available. Most standard under sink systems work on a 1:3 or 1:4 ratio, wasting 3 or 4 gallons of water for every gallon produced.
The Brondell Circle prevents backflow of water that often leads to a heightened water wastage, maximizing efficiency and speeding up the water tank refill process. Roughly 2.1 gallons of water are needed to yield 1 gallon of clean, pure water in this reverse osmosis unit.
🔧 Installation & Maintenance
Because the Brondell reverse osmosis system combines all filters and system components inside one unit, installation is fairly simple. The faucet must be installed in place of a standard kitchen sink faucet, and instructions are provided to assist in this process. Installation does not require the help of a plumber.
Maintaining the Brondell Circle is also a simple task. The system’s faucet has a built-in LED monitor that notifies the user when filters need changing, and new replacements can be bought online.
For cleaning the system, a user should run the system through with pure water. There is no need to remove the tank or other components for a more thorough clean.
📝 Filter Info
There are 3 filters in the Brondell Circle Reverse Osmosis Water Filtration System – a sediment filter, a pre-carbon plus filter, and a post carbon block filter. Also included is 1 reverse osmosis membrane.
Filters can be removed and replaced by untwisting to take off an old filter and twisting to seal a new filter in place. The RO membrane should be replaced every 2 years and costs around $100 online. A set of 3 replacement filters cost around $80 in total, and should be replaced every 6 months to a year, depending on water type and usage.
🔔 Pros & Cons
- The Brondell Circle is one of the most efficient RO units, and reduces water waste while refilling the tank at twice the rate of most under sink systems. This reduces bills and produces clean filtered water more quickly.
- With one compact unit and a separate designer faucet, this water filtration system is simple to install, with no wires or electric required. Installation instructions are simple and thorough, eliminating the need for spending money on a plumber to carry out the job.
- This RO system combines three separate filters and a semi-permeable membrane for the most efficient removal of contaminants and impurities. Filters are easy to change and relatively inexpensive.
- Auto filter flushing enables the Brondell Circle to extend the life of the semi-permeable membrane for between 2 and 4 years, reducing the need to buy filters as often.
- This system filters all impurities from water, including minerals like calcium, magnesium and potassium. Users wanting to benefit from these minerals in their reverse osmosis water will need to purchase an additional filter for remineralizing water before drinking.
- The single housing unit may not fit in a standard or smaller under sink space. Users should check the measurements of their under sink area when considering making a purchase.
- For users who are not so mechanically skilled, costs of hiring a plumber may need to be factored in for the installation process.
