What Customers Are Saying

The water filtration system has received mixed reviews. Many customers praise its easy installation and compact design, as well as the great taste of the filtered water. However, a significant number of reviews report issues with the system's durability and longevity, including decreased water pressure, leaks, and complete failure within 2 years, often just outside the warranty period. The high cost of replacement filters has also been a common complaint. While the system works well initially, it appears to have a 50/50 chance of providing long-lasting, high-quality filtered water.

Had it for 3 years

I love the compact and ease of filter changes but it’s now 3 1/2 years and religious on filter changes the system all of a sudden is now dribbling water and used brondell trouble shooting and looked online for ideas but no solutions and out of warranty. Black Friday just happened and went to another brand to maybe get more than 3 yrs out of the system

Completely satisfied

[This review was collected as part of a promotion.] So simple to install and have working from day one.No electrical connection required. Water flow is somewhat slow, but sufficient. Would be fine for a small family.

EXCELLENT SYSTEM!!!!!

I installed this system myself, about 2 years ago. It was quite simple for me, only because I am an avid "DIY GUY." I've done the filter changes, as required, and it works great! What I love the most, is that "All Enclosed" cabinet! (Have you seen the typical RO system? Yuck!)

Nice system

[This review was collected as part of a promotion.] So far this is a nice system. Took about 20 mins to install and I'm no plumber. It came with everything we needed. Directions were ok. For a household of 4 the system keeps up with our drinking water use.

Well the open box purchase

[This review was collected as part of a promotion.] Well the open box purchase looks pretty much new. I didn’t notice anything worn or scratched or anything. Install was simple for my location under sink. Unit looks neat and tidy with compact footprint. -1star because water flow is slow and future filter changes will be costly. But overall very pleased with this unit.

Need QA check before selling

On installation found leakage, uncoupled and coupled connector inside system and it worked. Love the product though I wish they QA every single system before shipping

Easy installation, compact unit

The Circle ROb unit has been running well for a few days and it's been great. Great tasting water, attractive tap and filter unit. Installed it myself in a couple of hours.

I had a little challenge

I had a little challenge with updating some old plumbing. After that the Brondell Circle RO Water filter was a snap to install. Now we have great drinking and cooking water with out the additional hassles we had to purify tap water.

My first RO installation

I had filtered tap water with a Water Wise unit for over 15 years. Now that I have a RO unit I can save time, energy, and money producing drinkable water that is refreshing and instantly available.

Love it

Would Recommend

Love this water purifier. It was the first thing I installed in my new home and use it everyday. It comes with everything you need to install including a 1/2in to 3/8in slip joint which I didn’t have for my new faucet install and required yet another Lowes trip. Exception is you need a drill to tap into the waste line.

Great tasting water with easy installation

This system was very easy to install. My daughter and I installed it in about 20 minutes. I already had a unit previously installed. So that really simplified things. I didn't have to drill any holes. My old lines actually connected to this unit also. But I wanted all new lines. The most complicated part was removing the old faucet. If you are thinking about hiring a plumber to install this, at least give it a try. If things don't work out, then call your plumber. Anyways, I chose this unit to ...

Super slow trickle

It's been 1.5 years into using this system. Installation is easy, however after 1.5 years and after replacing filters on time, we see the following 1) Water flows to normal after 1 minute.. until then it is a drop trickle. 2) Replacement batteries starts flashing red despite low usage and within 2 months 3) This could be an expensive option

Love it!

I was so pleased with my Circle Reverse system that I had installed in my kitchen remodel 5 years ago, that I bought one for my rent house and one for my daughter's house. They were easy to install, they take up very little space, and they work great!
