The DuPont Whole House 10-inch Carbon Filter WFPFC8002 specifications: 10" cartridge (nominal) 15,000 gallon capacity 5 gallon per minute flow rate 5 micron filtration Dimensions: 2,5" width x 9.75" height (fits ten inch standard housing) 2 per pack Update: I find they don't quite last as long on chlorine as the whirlpool filter cartridges do, but they do last longer on sediment removal. If you're in it mainly for a lot of chlorine removal you might find yourself replacing these more often than most.
