Enhancing Water Quality Through Advanced Adsorption

Only 3% of water found on earth is fresh water.


Water is the key requisite of sustaining all life on earth, it is the most sought-after ingredient in everyday life.  As humans, we know the water we have on this earth is finite. We cannot produce more. We drain rivers, build dams and drill far into the earth to find water and 97% of the water on Earth is found in the oceans. Only 3% is fresh water, and access to clean and safe water is paramount for the well-being of individuals and communities. In the pursuit of pure, refreshing water, technology has given rise to various methods of water purification. Among these, carbon block water filtration stands out as a highly effective and versatile approach to enhancing water quality.


At the core of carbon water filtration lies activated carbon, a remarkable material renowned for its ability to adsorb a wide spectrum of impurities. Activated carbon is produced through a meticulous process of exposing carbon-rich materials—such as coconut shells or wood—to high temperatures and controlled environments. This process creates a matrix of interconnected pores within the carbon, resulting in a vast surface area that acts as a magnet for contaminants. WaterWise sources the highest quality coconut shell carbons for use in our products.


Carbon Filtration is typically available in water treatment in two forms:

  1. Granulated Activate Carbon (GAC) – a fine powder-like version of carbon.

  2. Carbon Block, which is blended with a plastic binder, heated and either compression molded to a shape or extruded block which is heated and pushed through a plate (similar to Play-doh®) that defines the shape/profile and then cut to a specific length(s).

Both GAC and Carbon Block can be used as mechanical filter media while multitasking as an adsorption taste and odor reduction filter.  Carbon block has much greater capability as a mechanical filter than GAC because the pore size openings can be controlled at a much greater level through the manufacturing process.

WaterWise mostly offers the second type, extruded carbon block but we do utilize the GAC version in some of our Remineralizing cartridges.

Adsorption significantly enhances water's taste, odor, and overall quality.


The distinguishing feature of carbon filtration is adsorption, a phenomenon where molecules adhere to a surface due to attractive forces. As water courses through the intricate network of pores in the carbon block filter, impurities within the water come into contact with the activated carbon's surface. Organic compounds, chlorine, chloramines, volatile organic compounds (VOCs), and some heavy metals are among the contaminants adsorbed, effectively removing them from the water. This process significantly enhances the water's taste, odor, and overall quality.




Carbon block filtration excels at eliminating an array of contaminants that can compromise water safety and enjoyment. It is particularly effective at addressing unwanted tastes and odors that arise from compounds like chlorine. Additionally, it tackles organic compounds that can be present in water due to agricultural runoff, industrial discharges, and other sources. By removing these contaminants, carbon block filters offer a refreshing and pure water experience. Water treatment professionals call these removed contaminants “CTO” (Chlorine, Taste and Odor).



The design of carbon block filters often incorporates micropores within the activated carbon matrix. These micropores provide an extended surface area for adsorption, enhancing the filter's capacity to capture contaminants. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 32,000 sq ft!

Carbon block filters can be tailored to various filtration levels, with micron ratings (µm) indicating their ability to capture particles of different sizes. This versatility makes them suitable for a wide range of water treatment applications.


Micron ratings on a water filter indicate the smallest particle size that the filter is designed to effectively capture and remove from the water. The micron rating is measured in micrometers (µm), where one micrometer is equivalent to one millionth of a meter.

Human hair typically has a diameter ranging from about 30 to 180 micrometers (µm), which means it falls within the range of 20 µm to 180 µm. Therefore, human hair is larger than 5 micrometers and would effectively be captured by a filter with a 5-micron rating, even if we split the diameter 5 ways!

For example, if a water filter has a micron rating of 5 µm, it means that the filter is capable of capturing particles that are 5 micrometers in size or larger. Particles smaller than the specified micron rating might still pass through the filter.

Different water filters are designed with varying micron ratings to target different types of contaminants. It's important to note that the micron rating alone doesn't provide a complete picture of a filter's performance. Factors such as the filter material, design, flow rate, and overall filtration technology also play a significant role in how effectively a filter can remove contaminants.

Carbon filters often have lower micron ratings (e.g., 0.5 µm, 1 µm, or 5 µm) than sediment filters and are effective at removing finer particles and some microorganisms, as well as improving taste and odor by adsorbing organic compounds. For food service treatment of municipal water (which has already been made potable), a 5 µm rating provides exceptional capacity for removal of contaminants while reducing the potential to prematurely load with dirt and clog, stopping water flow to critical equipment. For any commercial food service operations that operate with well water, WaterWise recommends a sub-micron filter (e.g., 0.2 µm, 0.015 µm) to remove microorganisms and potential pathogens, bacteria, or viruses from the water. It is also advisable to treat such water with aqueous ozone generators (AOG) post filtration for an additional measure of safety.

It's important to note that the micron rating alone doesn't provide a complete picture of a filter's performance. Factors such as the filter material, design, flow rate, and overall filtration technology also play a significant role in how effectively a filter can remove contaminants.

When selecting a water filter, it's essential to consider the specific contaminants you want to target and choose a filter with an appropriate micron rating and filtration capability. Keep in mind that using filters with different micron ratings in a multi-stage filtration system can help address a wider range of contaminants and improve overall water quality.

It's important to note that while carbon block filters are effective at removing a wide range of contaminants, they might not be suitable for removing all types of impurities, such as certain minerals, heavy metals, or microorganisms. Depending on your water source and the specific contaminants you're concerned about, you might need additional filtration methods in combination with a carbon block filter to achieve comprehensive water purification.



Regular maintenance and filter replacement are essential to sustaining the effectiveness of carbon block filtration. Over time, activated carbon becomes saturated with contaminants, diminishing its adsorption capacity or clogged by fine particulate sediment. Timely replacement of filters ensures that water quality remains consistently high.

Carbon block water filtration offers a reliable and efficient solution for improving water quality. Its reliance on activated carbon's remarkable adsorption properties sets it apart as a versatile tool in the pursuit of clean, refreshing, and safe drinking water. By effectively removing a range of contaminants, carbon filtration enhances taste, odor, and overall water enjoyment, contributing to healthier lives and thriving communities.



While carbon filters are highly effective, it's important to recognize that they might not be optimal for every water source and every type of contaminant. For comprehensive water purification, carbon block filtration can be integrated into a multi-stage treatment system that includes other methods like sediment filtration, reverse osmosis, UF (Ultra Filtration) and O3 (ozone) disinfection. This ensures a comprehensive approach to water safety and quality.
