Brita vs. Reverse Osmosis: A Total Comparison

Reverse osmosis (R/O) is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores." Carbon Filters are often found in Brita water filters and these remove some chlorine from the water. As a water purifier installer in Kitchener, Waterloo, and surrounding areas for over 20 years, we at WaterSmart have learned that education is more important than making a sale. We want to equip you with the knowledge you need so that your family can be equipped with the right tools and information to keep your water soft and your home's plumbing in order. If you are interested in reverse osmosis as a water solution for your home, contact the local experts at WaterSmart today.

Brita vs. Reverse Osmosis



Carbon Filtration (Brita Filters)


Carbon filtration is one of the oldest technologies out there for filtering water. Most commonly today, they are known as the technology that Brita water filters or refrigerator filters use. These use a simple carbon gravel for their filter that will remove some chlorine. You can also buy carbon filters in block form, some with "activated carbon", also called "activated charcoal." These will remove more chlorine. A high-quality carbon filter removes 99% of the chlorine in water, however, these are not found in Brita filters but they are found in reverse osmosis systems. These systems are best for removing bad taste and odour, as seen in the chart above.




Reverse Osmosis (R/O)


Reverse osmosis, as mentioned above, is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores." Clean water passes through and impurities that are too big to pass through the membrane are left behind and flushed away. According to Engineering at Dartmouth, reverse osmosis was actually invented by French physicist Jean Antoine Nollet in the eighteenth century. However, it wasn't until 1969 that it started to be used as a commercial application when Dean Spatz used the process to separate maple sugar from sap. From there it has become a key process used in water filtration.

The Difference


Reverse osmosis and carbon filters are very different technologies. Carbon is not bad - it is often used in dechlorination. However, when it comes to whole home drinking water, there is a big difference. Reverse osmosis removes over 500x the microns that carbon filters will remove (as seen in the chart above). There are also many health benefits to reverse osmosis. 



Health Benefits of Reverse Osmosis


Because reverse osmosis uses a chemical treatment process to apply pressure to the water, through a series of specialized membranes, it enables foreign substances, molecules, and minerals to be removed. This process creates pure water that leads to a number of health benefits.


1. Free of Lead


According to the Centers for Disease Control and Prevention (CDC), reverse osmosis can effectively remove lead, making highly contaminated water safe for drinking. Lead can be very dangerous in high amounts, and can even lead to brain damage in children. However, in smaller amounts it can lead to increased blood pressure, problems with fertility, nerve and muscle damage, and more. Be sure to have your water tested and install a reverse osmosis system if you believe you may have a problem with lead in your water.


2. Safe For Cancer Patients


Cancer patients can consume reverse osmosis purified water during and after cancer treatment. During chemo and radiation, cancer patients have weakened immune systems. Untreated water, while often deemed harmless, can cause serious infections when immunity is compromised in cancer patients. Reverse osmosis purifies the water to the point that it is safe for cancer patients before, during, and after treatment.


3. Filters Cryptosporidium


Cryptosporidium is a parasite found in contaminated water. According to the CDC, reverse osmosis removes this contaminant. If water is not treated and this parasite is ingested, it can affect the small intestine, causing nausea, fever, and diarrhea. In children, symptoms can be more severe.


4. Removes Sodium


Because of the special membranes that are a part of the reverse osmosis filtering system, large sodium molecules cannot pass through into the drinking water. If you have high blood pressure, kidney or liver disease, or any other cause for sodium restrictions, you will want to ensure you have a reverse osmosis system installed in your home.



What Is The Best Reverse Osmosis System To Purchase?


There are many different brands of reverse osmosis systems to purchase. It is important to buy one that is high quality and also includes a carbon filter to block dangerous chemicals like pesticides, herbicides, and chlorine which are small enough to pass through the reverse osmosis filter. At WaterSmart we sell, install, and service Duro Reverse Osmosis systems. These high-quality systems come with both a pre and a post-carbon filter.
