EP Series Carbon Block Cartridges are manufactured using a process that yields a cartridge with a nominal 5-micron filtration rating and high dirt-holding capacity. A high porosity design helps prevent the cartridge from plugging before its adsorption capacity is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. Industry standard chlorine, bad taste and odor cartridge at an economical value Better chlorine reduction and 5 micron sediment filtration for residential chlorinated water supplies Standard 2.5" diameter by 10" length Better dirt holding capacity, minimizing pressure drop through life of cartridge
