The Brondell Circle reverse osmosis system is one of the top reverse osmosis systems available on the market. It has a few things that we like such as being super-efficient, looking great, a compact size, an LED filter change light, and a WQA Gold Seal certified filtration system.
Of course, it has some things we don’t like such as the
price. However, the benefits of this system definitely outweigh the negatives
and we still recommend it for the right person.
This is a four stage reverse osmosis system. All the filters
have a WQA Gold Seal certification, which means they are high quality. The four
stages are as follows.
Sediment Filter – This removes only
the largest contaminants found in the water. Think of stuff like rust, dirt,
pond scum, and other large stuff that somehow ends up in your water supply.
Pre-carbon filter – This mostly removes chlorine and other soluble
contaminants. Chlorine reduces the life of the reverse osmosis membrane, so
this stage is especially important to protect the life of your filter.
RO Membrane – The membrane works by pushing water through a very fine
membrane. Contaminants get caught in the membrane. In fact, most contaminants
get stuck in the membrane. Over 1000 to be exact and over 90% of all of them.
Yes, this includes fluoride. RO is the best way to remove fluoride from water.
A reverse osmosis system goes under the sink, so style isn’t
TOO important. However, you still want it to look respectable. This unit is
basically a black box with the filter stuff inside the box. This makes it look
great while also reducing the chances that you will accidentally damage the
A win-win type situation and something we definitely like
about this unit.
This is one of the more efficient reverse osmosis systems on
the market. It only wastes 2 gallons of water for every 1 gallon of filtered
water that it produces. This is because of the back pressure reducing smart
valve that it has in place.
Most systems have a lot of backpressure when the storage
tank is full, which produces a lot of waste water when topping off the storage
Brondell has one of the better warranty programs in the
industry. They offer a one year comprehensive warranty on all parts (except the
filter) for the first year. Just keep your receipt and take it to Brondell
authorized service center.
Another super easy unit to install. The instructions that
come with the unit are very comprehensive and easy to understand, which makes
installing this unit a cinch. I’d wager that most homeowners can probably
install this unit on their own. The hardest part is drilling a hole in your
sink. However, that may not be required depending on if your sink already has a
It’s also pretty easy if you have a metal sink. A thick
ceramic sink will be much more difficult to install.
Also, there are some great videos on YouTube on how to
install a reverse osmosis system if you’re more of a visual learner.
Maintenance is simple with this type of system. All you
really have to do is change the carbon filters.
Brondell makes this super easy with a flashing red LED light. This will appear once 6 months have passed or 475 gallons of water has been filtered.
It doesn’t really get any easier than this for changing the
filter. You don’t have to rely on the water pressure dropping or checking the
TDS of the water. Now, 6 months might be premature depending on the quality of
your tap water and how frequently you use the system. For instance, if you live
in Maine (very pure tap water), then you will probably have a slightly longer
filter life compared to someone in Florida (heavily chlorinated tap water).
However, this is just a precaution that the manufacturer
takes. They also want you to buy replacement filters (that’s how they make
