UDF 10" Cartridge Filter-Water Purifier

UDF cartridge filter is a Granular Activated Carbon (GAC) filter used in water-purification systems. It is usually filled with loose activated-carbon granules, often made from coconut shell, coal or other carbon sources. What does a UDF filter remove? Its main job is adsorption, so it is particularly useful for: Chlorine Bad taste Unpleasant odours Some organic contaminants Some colour-causing compounds Certain pesticides and VOCs, depending on the carbon and filter specifications UDF vs CTO Since you were asking about CTO earlier, the main difference is: UDF Granular activated carbon Carbon is loose inside the cartridge Large amount of carbon and good adsorption capacity Mainly used for chlorine, taste, odour and organic contaminants CTO Activated carbon is compressed into a solid block Provides both adsorption and physical filtration Generally provides finer particle filtration Commonly used as a more precise carbon stage in an RO system. For an RO system A common arrangement is: Sediment → UDF/GAC → CTO → RO membrane → Post-carbon The UDF helps remove chlorine and organic contaminants before the later stages
