SUPERPURE 20 inch Big Blue Carbon Block Filter (3 Pack) Carbon Filter Cartridge  (5 Mic, Pack of 3)

The SUPERPURE 20 inch Big Blue Activated Carbon Block CTO Water Filter (3-Pack) is a handy pack of carbon block filters designed specifically for your Big Blue Filter systems. Ideal for "point-of-use" water filters (under sink/ under counter, countertop systems) where fine filtration is crucial. Carbon Block Filters are made from finely ground activated carbon particles that are bonded together and formed into a solid block under high pressure. They have a uniform structure that's density can vary depending on the manufacturing process. Due to their dense structure, they generally have a slower flow rate but provide more comprehensive contact time, allowing for better contaminant removal. The tight filtration structure also enables the removal of smaller particles and impurities due to the fine micron rating. Active Carbon is carbon that has been treated with oxygen to make it porous, but it has also been broken up into granules to further increase the surface area for chemical bondage to occur. The water passes through the GAC filter, allowing the organic materials and chlorine to effectively bond with the carbon molecules, thus removing these from the water. Activated Carbon has a high surface area, providing a large number of adsorption sites for contaminants; this allows it to effectively adsorb a wide range of impurities, such as volatile organic compounds (VOCs), chlorine and odours from your water. GAC is particularly effective at removing organic contaminants from water due to its affinity for organic molecules. It can efficiently adsorb organic compounds, such as; pesticides, herbicides, industrial chemicals, and natural organic matter, improving the taste, odour and overall purity of water. Carbon is effective at removing chlorine and chloramines, which are often added as disinfectants during the water treatment process, GAC effectively adsorbs these disinfectants, reducing their concentration in (often municipal sourced) treated water and improving its overall taste and odour for your enjoyment and consumption. The Activated Carbon Block is enclosed in a 5-micron filter to catch tiny carbon dust particles that may break off during the filtration.
