Brondell H2O+ Circle Water Saving Reverse Osmosis Review

Brondell Circle Reverse Osmosis ReviewThe Brondell H2O+ looks very different from the vast majority of reverse osmosis (RO) filter systems. With this system everything is enclosed in a box. This reduces the number or exposed tubes that are under your sink and looks a lot tidier.

In addition to having a novel look, the Brondell H2O is also highly efficient when it comes to water usage. While most RO systems make about 4 gallons of waste water for every gallon of pure water produced, the H2O+ makes only a little over 2 gallons of waste water for every gallon of pure water produced. The system has what Brondell call an intelligent “smart valve” and along with a circular reservoir, this helps eliminates backpressure. This helps make the H2O+ about the most efficient non-pumped RO system available.

The system uses a 4 stage filtering arrangement to produce the pure water;

Stage 1: Sediment filter reduces particulate materials such as sand, rust, and fine particles from the feed water. This first helps act as a pre-filter to protect and help extend the life of the other filters.

Stage Two: Pre-Carbon Plus filter significantly reduces volatile organic compounds (VOCs), chlorine, and soluble contaminants which may damage the RO Membrane filter.

Stage Three: RO Membrane filter works by forcing water through a semi-permeable membrane. This separates water from contaminants reducing pollutants such as heavy metals, cysts, fluoride, arsenic, and industrial chemicals.

Stage Four: Post Carbon Block filter further reduces any remaining water contaminants such as chlorine and VOCs improving the overall taste and odor of the water.

Brondell supply stickers for your filters to remind you when to change them, but another innovation that this system has is an LED indicator light on the faucet. This lights up when you need to change your filters. This could well be very useful as the quality of the feed water is ultimately what influences when the filters need changing. The better the water that flows into the system the less frequently the filters need replacing.

Filtration System Design

With the Brondell H2O+ not only are the filter modular, the whole system is. The filters and water reservoir are all contained in a neat package that fits in cupboards under most counter tops.  The 6 liter (1 ½ gallon) tank is also enclosed within the unit. This means that even if the unit is in an exposed area it won’t look out of place.

The filters are easy to change. The front of the unit opens and each filter is changed by giving it a ¼ turn, by hand, and pulling it out. The filters, based on 2 ½ gallons of water per day are replaced every 6 months, although this can vary depending on the quality of the water that is fed into the system. The RO membrane should be replaced every 2 years.

The faucet has a filter change indicator on it. When the water is dispensing normally the indicator will flash blue. After 6 months or 475 gallons of water is dispensed the light will start flashing red to let you know that the filters need changing. The light is reset by replacing the battery which is included in Brondell’s filter change kit.

Water Efficiency

While the Brondell H2O+ is not the most efficient RO system available, it is one of the most efficient (in terms of water wasted to every gallon of pure water produced). The most efficient units are those with pumped water. Similar units to the Brondell H2O+ waste 4 gallons of water for every gallon produced whereas the Brondell H2O+ averages 2.1 gallons wasted for every gallon produced. This increased efficiency is not at the loss of the efficiency of the system, see this data sheet for the effectiveness of the filtration. Most of the toilets today has the same sort of water saving.

Ease of Installation 4.8/5

The Brondell H2O+ is a very easy system to install. The only area that may present any problems in drilling a hole for the faucet – this will be the same for any RO filter system. Many sinks will have a blanked off hole or a spray nozzle that can be used for the pure water faucet.

Once the outlet faucet has been located, the feed in pipe needs to be attached to a cold water supply. This can be done by disconnecting the flexible supply hose, putting the supplied ‘T’ connector on the end of the pipe and reconnecting. All the connections for flexible tubing are carried out by means of ‘push to fit’ connectors.

The waste is connected via a saddle connector to the existing waste water pipe. Once the connectors have been fitted the three pipes, feed, waste and outlet, are connected to the appropriate connection on the top of the Brondell H2O+.

Cons

While this unit will fit in most under counter cupboards, as the tank is contained in the unit some flexibility may be lost in siting the system. The dimensions are 9.25” (W) x 13.8” (D) x 16.5” (H)

Conclusion 4.7/5

The Brondell H2O+ review showed that there is a different approach to a RO filter system than those used by the majority of system manufacturers. The area that deserves the greatest praise is in the use of the smart valve and circular reservoir. This makes the H2O+ about twice as efficient as similar systems in terms of wasted water per gallon of water produced.

The only possible drawback with this type of kitchen may be in the occasional kitchen that does not have sufficient space to fit an all in one unit such as this.
