The GE SmartWater FXUSC is a 30-micron sediment filter designed to reduce dirt, rust, sand, and sediment from your entire home's water supply. Each FXUSC cartridge has a filtration capacity of approximately 16,000 gallons or should be replaced every 3 months, whichever comes first. Since this 2-pack includes two cartridges, you get roughly 6 months of protection for standard household use.

The GE FXUSC cartridge is specifically engineered to fit GE whole house filtration systems, including models GXWH35F, GXWH30C, GXWH20S, GXWH20F, and GNWH38S. It measures approximately 9.75" in height and 4.5" in diameter, making it a standard "Big Blue" sized cartridge. Always confirm your housing model before installation to ensure proper fitment and sealing.

The GE SmartWater FXUSC is a dedicated sediment-reduction cartridge only — it does not reduce chlorine, taste, or odor. Its pleated cellulose design targets particulate matter like sand, silt, rust flakes, and scale particles at 30 microns. If you also need chlorine reduction for your whole home, GE recommends pairing the FXUSC with a carbon-based cartridge such as the FXHTC in a dual-stage housing setup.

GE recommends replacing the FXUSC every 3 months or after 16,000 gallons of use. However, replacement frequency depends on your incoming water quality — homes with well water or high sediment levels may need to change the cartridge more frequently. A noticeable drop in water pressure throughout the house is a clear sign it's time to install a fresh FXUSC cartridge.

Yes, the GE FXUSC is tested and certified to NSF/ANSI Standard 42 for mechanical filtration and Class III particulate reduction (5 to 50 microns). This certification verifies the cartridge's ability to reduce visible sediment and particulates from your home's water supply. The pleated design also allows the FXUSC to be rinsed and reused short-term between replacements, maximizing its service life.
