The North Star NSDW300R is a replacement full-flow water filter cartridge for the NSDW300 under-sink system, rated at 2.0 GPM with a service life of approximately 2,000 gallons (about six months). The cartridge uses a twist-and-pull sanitary design for quick change without shutting off the water supply and connects to the cold water line via 3/8" quick connect fittings. It reduces chlorine taste and odor, sediment, cysts, and microplastics and is NSF certified.
