The Benefits of Carbon Block Filters for Water Purification

When it comes to water purification, carbon block filters are one of the most effective solutions. Activated carbon, a form of carbon that has been processed to increase its porosity and surface area, is used in these filters to remove contaminants from water. Carbon block filters are more effective than other types of filters, such as granular activated carbon (GAC) filters, due to their increased surface area and ability to control the pore size. Plus, they come in a variety of sizes and configurations, making them suitable for a wide range of applications. The two main mechanisms by which activated carbon filters remove pollutants from water are adsorption and catalytic reduction.

Adsorption is the process by which negatively charged polluting ions are attracted to the positively charged activated carbon. Catalytic reduction is a process in which contaminants are broken down into harmless compounds. Carbon block filters can also reduce particulates, microscopic cysts, lead, volatile organic compounds (VOCs), and other contaminants. The amount of carbon in the filter and the amount of time the contaminant spends in contact with it are two of the most important factors that affect the efficiency of activated carbon filtration. Coconut shell charcoal is generally considered to be the most effective type of carbon used in water filtration, although it usually costs 20% more than other types.

Carbon block filters should last between 2 and 6 months before needing to be changed, depending on the brand and model. In addition to improving the aesthetics of water, carbon block filters also reduce the risk of microbial contamination. According to a study conducted by the International Journal of Hygiene and Environmental Health, carbon block filters do not pose a significant microbial risk to users. The uniform porous structure of the carbon block also increases its ability to remove contaminants. Sediment prefilters can also extend the lifespan of active carbon cartridges by removing serious contaminants that would otherwise clog activated carbon and reduce its surface area available for absorption. Carbon block filter cartridges are readily available in standard sizes and configurations for drinking water treatment.
