DuPont whole house water filter technology increases clarity of your entire home’s water by reducing sediment, which extends the life of appliances that process water. These filters fit most other brands of whole house water filters. The DuPont Pleated Poly Whole House Cartridge reduces Sediment. The Pleated Poly cartridge consists of Poly Pleat construction versus paper construction. Poly construction is stronger and will not break down as quickly in the water. The unversal design means it is compatible with GE, Whirlpool, Culligan, Omni, Watts and most standard size water filter systems.
