By selecting a GE water filter, water heater, and water softener for your home, you can improve how your water tastes and smells and how it feels to your skin. In addition, water filtration and softening can help ease cleaning and protect plumbing and appliances. Household filtration reduces sediment, sand and rust at the main water supply so there's less build up inside water heaters, pipes, dishwashers and other appliances and fixtures. The filter is compatible with systems GXWH40L, GXWH30C, GXWH35F, GXWH38F, GNQH38S and most systems with 10 in. x 4.5 in. filters.
