Filtration Process

Brondell H2O+ uses 4 filtration stages to purify the water, including pre-filters, RO-Membrane, and the Post filters.

Every filter performs its own unique task to provide you with completely filtered water.

Let’s have a look at how these stages work together to serve you in a better way.

Stage 1: This stage is also known as the sediment stage, which removes the minute separate particles like dust, odor, rust, and many other tiny particles.

Stage 2: It works as the saver of the RO-Membrane, Reduces the chlorine, Organic compounds, and other soluble contaminants from the water.

Filtration Process

Stage 3: This stage is the RO-Membrane, it’s the main stage of filtration as it removes all the possible contaminants from the feed water and works to separate the water completely from harmful and impure substances.

Stage 4: This stage ensures that you are drinking healthier and cleaner water by removing all the remaining contaminants from the water before you drink.  It is the last stage of filtration that helps you to have a better experience with the produced water.

The filters at the first 2 stages are the Pre-filters, and the filters that work after the RO membrane are the Post filters.

That’s how these stages work together for you. After passing the water through these 4 Stages there is no doubt that you are drinking safer, cleaner, and healthier fresh-tasting water.

Water Efficiency

The water efficiency is measured by the water waste Ratio. The RO systems with water waste below 3-4 are considered efficient systems.

Brondell H2O+ has a smart valve that eliminates the back pressure and also has a reservoir that extends and contracts for the consistent water flow. These two technologies in the system make it an efficient system.

Water Efficiency

Brondell circle is rated for producing 1 gallon of purified water by flushing down around 2 gallons of water. Even without the pump and the usage of Electricity, it is capable of competing with other high-end RO systems that use a pump to reduce water waste.

Water Output

Brondell H2O+ is rated for producing around 50 Gallons per day at the standard water pressure. The water production can be reduced in areas where water pressure is even below the standard. Similarly, at such places along with the Water output reduction, water waste could be increased.


The innovative modern design of the Brondell circle makes it easy for you to install. You don’t need to call any professional for the setup. It is designed in such a way that anyone setup the systems within one hour.

To master the installation process, Reading the manual that comes along the system would be the best choice. The instructions manual is well written and seems like that it is written by the technical writer by keeping the customers in mind.

Most of the people actually start the installation by taking a look at the procedure, it is suggested to learn first before installing the system.


If you don’t want to read the manual, the video tutorials are also available online to help you out. You can follow them to get the water filter right into your kitchen.

After installing the system, turn on the water you will have the water Right within 40-45 minutes, but it is recommended in the instructions to drain it once before using it.

Refill the system, don’t worry the System refill rate is half the time of other conventional RO systems. After refilling now you can drink the water as much as you want.

All the essentials for installation will be inside the box, you only need to have the adjustable wrenches and the drill for the wastewater connection.


The filters need to be replaced if you want to operate the RO system at its potential level. The filters are not needed to replace more often, but it depends on the quality of the feed water.

According to the standard, the pre-filters and the post-filters should be replaced every 6 months. And the RO –membrane after every 2 years.


RO-Membrane being the main player in the filtration process is a little bit more expensive than the other replacement filters. It’s hard to find the filters of this Unit on Amazon, but can also be purchased from their own website.

The Process of the replacement is not intuitive, if you have installed the system by yourself then the replacement will not be an issue for you. Even if you have not installed the system, still you can do this because it’s just the plug-and-play game. You don’t even need any tools.
