Any home is a big investment. Adding a GE whole house water filter system helps reduce sediment, sand and rust at the main water supply so there is less build up inside water heaters, pipes, dishwashers and other appliances and fixtures. A home filtration system can also help provide clean, clear water for showers, dishwashing, and laundry. The filter is compatible with systems GXWH40L, GXWH30C, GXWH35F, GXWH38F, GNQH38S and most systems with 10 in. x 4.5 in. filters.
