Reviews

Reverse osmosis (RO) systems today are bulky, difficult to install, and many require electricity and pumps to operate. Most importantly, conventional RO systems are extremely inefficient, wasting up to 24 gallons of water for every gallon of drinkable water!

Brondell's Circle Reverse Osmosis Water Filtration System utilizes patented new technology to eliminate back-pressure, making it up to 10 times more efficient than current conventional RO systems. Additionally, the Circle RO Water Filter eliminates any need for electricity by integrating the tank and filters. Brondell's Circle is an all-in-one, easy-to-install complete system.

The Brondell H2O+ Circle RO Water Filter’s exclusive Smart Valve and unique circular reservoir design are the keys to its efficient design. This special technology eliminates back-pressure on the RO membrane filter, making the Circle RO Water Filter a leader in RO efficiency. The Circle RO Water Filter reduces wastewater to an average of 2.1 gallons for every gallon of drinking water – up to 10 times more efficient than many conventional RO systems currently being sold (and in some cases, even over 10 times as efficient). In addition, the Circle RO Water Filter’s refill rate is more than twice as fast as non-electric systems, and equally as fast as those with electric pumps. We’ve also simplified installation and maintenance with features such as auto-flushing, twist-and-seal filter changes, and “quick-connect” connections. The Brondell H2O+ Circle RO Water Filter delivers water savings, power savings, and space-savings - all in a beautiful, simplified design.

The Circle Reverse Osmosis Water Filtration System utilizes four separate advanced water filters, dramatically reducing industrial chemicals, heavy metals, pesticides, herbicides, total dissolved solids (TDS), volatile organic compounds (VOCs), microorganisms, and bad tastes and odors. Reduce harmful chemicals like fluoride; atrazine; hexavalent & trivalent chromium; chlorobenzene; trihalomethanes; methoxychlor; endrin; 2,4-D; benzine; DBCP; pentavalent arsenic; barium; radium; cadmium; lead; and aesthetic chlorine from your tap water for a healthy home and family.

The Circle RO Water Filter easily installs under your kitchen counter, and everything needed for installation is included. This is the fastest, easiest, most elegant, and most efficient high-quality reverse osmosis system available.

The Four-stage Brondell H2O+ Circle Reverse Osmosis Water Filtration System (RC100):*

SEDIMENT FILTER* (Stage 1): The sediment filter reduces particulate materials such as sand, rust and fine particles from the water supply. The first stage also acts as a pre-filter, protecting and extending the life of the following filters.

PRE-CARBON PLUS FILTER* (Stage 2): This second stage filter significantly reduces harmful VOCs, chlorine and soluble contaminants, which can damage the RO Membrane filter.

RO MEMBRANE FILTER** (Stage 3): The RO membrane filter works by pushing water through a semi-permeable membrane, thereby separating H2O molecules from contaminants in the tap water. The powerful RO membrane filter significantly reduces pollutants such as: heavy metals, cysts, fluoride, arsenic, industrial chemicals and more.

POST CARBON BLOCK FILTER* (Stage 4): As the final stage in the filtration process, the post carbon block filter further reduces any lingering water contaminants such as chlorine and volatile organic compounds (VOCs), improving the overall taste and odor of the dispensed water.

*Recommended replacement is every six months.
**Recommended replacement is every 24 months.

Brondell H2O+ Water Filtration FAQs

 


 

FEATURES & PERFORMANCE

 

Do the Brondell H2O+ water filtration systems come with the filter(s)?

Yes, all of the Brondell H2O+ water filtration products come with the filter(s) you'll need for operation. When you are ready for replacement filters, they are available HERE for purchase.

 

Do any of the Brondell H2O+ water filtration systems remove fluoride?

Fluoride is a naturally-occurring mineral found in many foods and water. Fluoride helps to promote dental health and has other beneficial qualities when present in small quantities, as found in most municipal water systems, usually in the form of sodium fluoride. However, we realize that some people still want to completely remove fluoride from their drinking water. The Brondell H2O+ Circle Reverse Osmosis system removes fluoride from water and is certified by the WQA (Water Quality Association) for Fluoride reduction, while the Cypress, Pearl, and Coral leave the mineral in. It’s very rare to find quality filtration systems (other than reverse osmosis systems) that are capable of removing any substantial amount of fluoride from drinking water. Beware of uncertified claims from manufacturers claiming to remove fluoride with non-RO systems.

 

When I use a Total Dissolved Solids (TDS) reader to test my water after it goes through the H2O+ water filtration system, why don't the levels of dissolved particles go down or decrease?

The Cypress, Pearl, and Coral water filter systems are not designed to remove beneficial minerals from your drinking water. These minerals (calcium, magnesium and sodium, to name a few) that occur naturally are a healthy part of your drinking water and should remain included in it. The Brondell filtration systems, such as the Cypress, are designed to dramatically reduce water-soluble harmful contaminants, including industrial chemicals, pesticides, herbicides, turbidity, volatile organic compounds (VOCs), and microorganisms, most of which cannot be "read" with a TDS reader since they are water-soluble. Contrary to the name (Total Dissolved Solids or TDS Meter), these inexpensive "readers" cannot detect most harmful water-soluble contaminants. There is a major misconception that low TDS readings mean healthy water and that is simply not always true. You will, however, see a dramatic reduction (90%) of TDS readings when using a reverse osmosis system like the Brondell Circle Reverse Osmosis filter, as it removes all minerals from your water.

The best method for testing the performance of a water filtration device is to have a nationally recognized independent organization, such as WQA or NSF International (which began its tenure as the National Sanitation Foundation), test and certify the products. The certified data is then available in a Performance Data Sheet, which you should request from the manufacturer. For more clarification of what the Brondell H2O+ water filtration systems do remove from your water, please see our Certified Performance Data Sheets for the Cypress, Pearl, Pitchers, Coral, and Circle RO System.

 

Do these filtration systems utilize reverse osmosis (RO) technology?

The Cypress, Pearl, and Coral water filtration systems all utilize carbon-based filtration technology (the Cypress adds a Nanotrap membrane-based filter as well), while the Circle is a Reverse Osmosis (RO)-based filtration system. RO systems strip the water of most everything (including many beneficial minerals), however they can be necessary to remove certain contaminants in various parts of the country. They are also necessary for removing fluoride in your water, should that be a priority for you. Issues with typical RO systems include: they can waste up to 24 gallons of water for every 1 gallon of drinkable water; they require large storage tanks, and they are expensive and complex to install. The Brondell Circle RO System eliminates these problems (and is up to 10 times more efficient than other systems!) by wasting less than 2 gallons of water per gallon of drinking water produced. The Circle also has an integrated tank and sophisticated non-electrical design. The Pearl countertop filtration system utilizes carbon block filtration technology and easily installs onto your existing faucet. The Cypress system is small enough to sit comfortably on your counter top, very easy to install at the faucet or under the sink, and uses a carbon block pre-filter, Nanotrap filter, and a secondary final carbon block filter. The Coral water filtration systems dramatically reduce industrial chemicals, pesticides, herbicides, turbidity, volatile organic compounds (VOCs), microorganisms, bad tastes, and odors from your tap water for a healthier home and family.

 

Is there an automatic water filter replacement reminder system?

Yes, the H2O+ Pitcher has a date-set reminder, while the Pearl has a color reminder when it's time to change the filter. The Cypress system requires that you write on the filters either the date they were put in or the date they should be changed, as 2 of the filters have a 6-month life and the remaining filter has a 12-month life. Brondell’s under counter Coral Systems as well as the Circle Reverse Osmosis System both include a chrome faucet with an integrated LED filter change indicator.

 

Which of your systems remove chloramine, lead, mercury, and asbestos?

The Coral UC300 and UC100 under counter systems reduce chloramine, lead, mercury, and asbestos, and a full list of reduced contaminates can be found HERE.

 

Do any of your filters remove Perfluorinated Chemicals (PFCs) from drinking water?

Currently, PFC's are not on the standard VOC list for NSF or WQA certification, both of which we have. So while we have not been certified in our testing for removing these contaminants, all of our systems will significantly reduce these chemicals.

 

Are your filtration systems phalate- and BPA-free?

Yes, all parts in contact with water are phalate- and BPA-free.

 

I just installed my water filtration system and my water looks cloudy. What’s wrong?

When water filters are first installed, it is common to see tiny bubbles in the filtered water. With enough bubbles, the water can appear somewhat cloudy. This is due to trapped air inside of the carbon pores of the filters. These bubbles are released over time and will quickly reduce in a day or two, when more water is filtered through the system.

 

How long are the Cypress and Pearl water filter hoses?

The Cypress hose is 60" and the Pearl hose is 32". They are ¼” polyethylene LLDPE tubing, are certified for NSF 61, and are made specifically for drinking water systems.

 

Do the Cypress or Pearl filtration systems change the pH level of the water?

Water filtered by the Cypress or Pearl systems will have the same pH as the unfiltered water.

 

What is the pore size for the Pearl Carbon Block filter?

The Pearl Carbon Block filter has a pore size of 0.5 micron.

INSTALLATION & USE

 

How do you remove the water inlet plug on the back of the Cypress water filter?

To remove the water inlet plug on the Cypress, use the universal quick-connect tool to hold down the lip around the plug, and gently pull the plug out. You can view the "Quick Tutorial on Quick Connects" HERE. This tool can also be used to disconnect the internal lines connecting the filters and can be found inside the top of the lid.

 

Will the Cypress and Pearl fit my faucet?

With the provided adapters, the Pearl and Cypress water filters should fit almost any aerator-style faucet. However, if you have an integrated pull-out or pull-down sprayer-type faucet, the Pearl will unfortunately not work. Instead, you can still install the Cypress at the connection under the sink with a T-valve adapter, found HERE.

 

What do I need to complete the under-counter installation for the Cypress?

You will need to first check the connection size joining the cold-water supply valve and the hose running to your sink (it should be either 1/2" or 3/8" in size). Then you can purchase the proper size T-valve from Brondell and follow the alternative installation in the owner's manual found on page 6. For reference, the Cypress quick-connect water supply hose is 1/4" in size which will need to feed under your sink for the alternate installation.

CIRCLE REVERSE OSMOSIS (RO) FILTRATION SYSTEMS

 

Does the Circle Reverse Osmosis System require an air gap faucet?

The Circle RO System does NOT require an air gap faucet. There is anti-backflow built into the system, and the entire system is certified by the Water Quality Association (with the included faucet).

 

Does the Circle Reverse Osmosis system remove sodium?

Yes, the Circle RO System will significantly reduce or eliminate sodium and aqueous salts.

 

Does the Circle Reverse Osmosis system re-mineralize the filtered water?

No, the Circle RO System does not re-mineralize the filtered water. Needed minerals can be consumed through food by eating a healthy, balanced diet.

 

What is the faucet flow rate for the Circle Reverse Osmosis system?

The faucet dispenses water at a rate of between 0.26 and 0.37 gallons per minute (gpm) when the incoming water pressure ranges from 20-100 psi.

 

Will the Circle Reverse Osmosis system get my TDS reading down to zero?

The TDS will not go to absolute zero and usually fluctuates between 5-10 ppm. After water moves through the pre-filter, carbon block filter, and RO Membrane, the TDS reading will be very near zero. After this the water moves through a final carbon block filter before exiting the faucet. At the last filter state the water can pick up a small amount of TDS particles from the carbon, but that's normal and proper functionality.

Circle Reverse Osmosis Water Filtration System is rated 4.8 out of 5 by 6.
Rated 5 out of 5 by from Sweet water! Literally! I bought this system 2 weeks ago and can't go back to regular tap water. The installation was quite easy even with having to drill a hole in our sink to install the tap. We drink a lot of water, so this is definitely worth every penny compared to other systems on the market. No more filling up pitchers over and over throughout the day. This system removed the strong chlorine smell and taste and made our water actually taste SWEET! Another plus is it doesn't require electricity so super savings! The only thing I'd love that would make this system even more awesome is if Brondell created a remineralization system to go along with this filtration system.

Rated 4 out of 5 by from Simple Installation I bought the Circle RO two weeks ago and am pleasantly surprised. The installation instructions were clear, concise and easy to follow. After completing the installation and flushing procedures, I checked the TDS, pH and waste water. All parameters were well within Brondell's claims - waste water for the last 250ml of the tank fill was 650ml, the TDS went from 98 to 6 and the pH dropped one point. The tank, while not overly large, refills so fast it is not an issue. I would not hesitate to recommend this system and will update my review after it has been in operation for a few months.

Rated 5 out of 5 by from GR8 Water-Easy as 1-2-3 I have limited use of my dominant had and was concerned with how difficult installation would be. Well, I was EXTREMELY surprised at just how simple and quick it was. Having had RO systems in all of my previous home (5) this one seems to be versatile and compact. I would recommend it for tight spaces and "non-plumbers". Anyone can install this thing! (just make sure you can fit under your sink! LOL)

Rated 5 out of 5 by from Successful choice I bought this system two weeks ago at Costco.ca. Delivery was very fast. I remember it took only 2 days. The reason why I bought the filtration system is my town has hard water which tastes bitter. So, I searched many water filtration systems by my criteria. First, It should be simple and easy to setup. And second, it should be easy to change filters. Third, it should not use electricity because electro circuit means high possibility of "out of order". Finally, I choose this filtration system with those criteria. I am very satisfied with this system. It took just ten minutes to set it up even though I am not a skilful handyman. The setting way is very simple and the guide is easy to understand. And, the taste of filtered water is wonderful. I have filled water bottles at Canadian Tire. But, the taste of water by this system feels way better. No order. A little sweet taste. I can feel the filtered water is good even though I didn't take pH check or any other technical tests of water. And, I like the Reverse Osmosis of this system. In my knowledge, by reverse osmosis, I can have bacteria free, virus free, metal ion free water. Only pure water molecules pass through the reverse osmosis system. I believe the reason why the water taste is sweet is the reverse osmosis system's power. At the first moment, the water flow from the tap was very week, but soon it became strong enough to fill a 4L milk bottle within 1 minute. I guess It takes time to fill the reservoir in the system. Until now, this system is very good and I enjoy a sweet water.
