Ratings & Reviews for Brondell Circle Reverse Osmosis 4-stage Multi-method Under Sink Water Filtration System

Easy Installation

I was excited with my new Circle RO Water Filtration System. I'm not handy with a lot of home repairs, but the installations of this RO system was so easy, just three tubes - Input, Output and Drain. You will not go wrong with the tubing. Another good feature is the water pumping mechanism does not require electricity all. My area always has power outage during summer or strong wind weather. During the hot summer days, it will not be fun to have no drinking water.

easy installation water tastes great

The compact design is great, and the install was overall easy. The installation video is very helpful. The only issue I had was after waiting 40 minutes and then drain the tank, the water just trickled out like others have posted. I assumed that there was still air in the lines so I opened and closed the faucet a few times waiting a few minutes in between the cycles. Suddenly you could hear the wastewater begin to drain out... I did not hear this at all during the 40 minute wait time.. so it act...

What we've been missing!!

Even after several brand new whole home filtration units the difference in quality of our well water with this unit is incredible! We had it tested afterwards and were told its the most perfect water he had ever tested!!

A perfect RO system with better space management

This is one of the best RO System that I explored that fullfills all my needs with better space management. Took me less than an hour to go through the installation video and fixing it and it is super easy. Leaves lot of space under the kitchen sink unlike other RO systems that occupies entire side of the space. The LED indicator on the faucet for filter change avoids to put reminders to change the filter. Highly recommended.

lovely product

very simple installation，easy to use。whole family love it.

Easy Set up

This is my 3rd Circle and the set up seems like it is much improved. The unit takes 15 min to set up and about 1 hour to fill and purge twice once it is working. Love the clean water and trouble free RO system with near 0 waste water.

Great for what I ordered. Now please take me off your text l

Great for what I ordered but I have requested 3 times or more to be removed from their text list. They still haven’t responded.

Awesome Product

EZ install, sleek design, great tasting water. I had a reverse osmosis system from a competitor and I'm glad I decided to change. The brondell filtration system takes a lot less space with a cleaner install.

Easy install

This was easy to install from the plumbing aspect but ran in to difficulty with my farmhouse sink. I needed to cut a notch out of the plywood support in order for the unit to sit upright under the sink. It would be great if the dimensions could be changed to allow the unit to sit on its side

Awesome System

The install was super easy, and the water quality is amazing! So worth it!

Brondell H20+Circle Reverse

I bought this without doing much research, luckily I bought the best! I needed a reverse osmosis system due to having well water where I live. The water now tastes amazing and the filters are cheap compared to other systems! Great buy!!! I would recommend this system to everyone! My mom also has a bidet by Brondell and it is amazing as well! Must be the brand! Great job to Brondell!!

Great tasting water, but terribly slow

The water from this unit tastes simply perfect! Unfortunately the flow rate is insanely slow. If you’re filling a big glass, best to put the glass in the sink, turn on the faucet, and do a small chore. If you don’t mind an exceptionally slow fill, but enjoy exceptionally delicious water, this is the perfect system for you.

Takes up less space and easy to change filters

I bought this system November 2018. It works great and so happy to have clean water to drink and cook with.

Best water I’ve ever tasted!

We bought our Brondell Circle about 2 months ago and I have to say I have never been happier with a water system. The water is pristine still and the taste is so good, I can’t get enough of it. I am constantly drinking water and continuously filling another glass. We love it!!! I definitely recommend this system!

Best tasting water

I'm so glad we finally tried this. I put lemon, lime, and or oranges in my water and I'm not competing with chemical smells of taste. I've had water filters over 50 years and this is the best.

Great Tasting Water

We recently bought our Circle Reverse Osmosis System. It was very easy to install. The only problem we had was the old plumbing did not fit the new system's fittings. We replumbed under the sink and it was very simple and fast after that. The water is delicious. We will see how long the filters last with our hard water.

Great Reverse Osmosis

Great system and super easy to install. The unit does not take up as much space under the cabinet as other units do. Would definitely recommend!

Easy install

Picked up my RO filter last week, easy install. I feel soo much better about what I’m drinking.
