Uses a replaceable carbon block cartridge, in a single space-saving housing. This cartridge is manufactured using a patented process that yields a cartridge with a nominal 5 micron filtration rating, 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, 3,000 gallons chlorine taste & odor reduction. Flow rate is .75 to 1 gallon per minute.<\/p>\n
