This SUPERPURE 20 inch Slimline Replacement Filter Set - Premium (Set of 3) is a premium 20 inch size set of replacement filter cartridges, offering you 3 stages of high quality filtration for your 20 inch size Slimline (2.5") filtration systems. Ensure your water filtration system operates at peak performance with the SUPERPURE 20 inch Replacement Slimline Filter Set - Premium. This premium set includes a 5-micron sediment filter, a granular activated carbon (GAC) filter, and a carbon block filter, designed to provide superior filtration and improve water quality. Ideal for replacing the filters in your 3-stage 20" Slimline filter systems, these filters should be replaced every 3-6 months, depending on your water quality and usage. 3 Filter Cartridges in One Set: 5-micron Sediment Filter: Specifically designed to capture and remove fine particulate matter from water. The term "melt blown" refers to a manufacturing process where a polymer is melted and then extruded into a matrix of fine fibres, providing comprehensive sediment filtration melt blown filters are engineered to have a high dirt-holding capacity. This means they can accumulate a significant amount of sediment before needing to be replaced, which extends the service intervals and reduces maintenance frequency. Granular Activated Carbon Filter (GAC): Granular 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. Granular Activated Carbon (GAC) 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. 5-micron Carbon Block Filter: A Carbon Block filter has almost the same benefits of a GAC filter, but with the added minute filtration of a block type filter. Carbon Block Filters are made from finely ground activated carbon particles that are bonded together and formed into a solid block under high pressure. Due to their dense structure, they enable the removal of smaller particles and impurities due to the fine micron rating. Incorporating both a Granular Activated Carbon (GAC) filter and a Carbon Block filter into a single water filtration system can provide a comprehensive solution that optimizes water quality by leveraging the unique advantages of each type of filter. Following up with a Carbon Block filter after a GAC filter allows for finer purification, catching any smaller particulates or contaminants that might have passed through the GAC filter. This results in even cleaner, purer water.
