Frequently Asked Questions

Which refrigerator models is the Tier1 RWF1181 compatible with?

The Tier1 RWF1181 is specifically engineered as a replacement for Frigidaire PureSource Ultra II (EPTWFU01) refrigerator water filters. It fits a wide range of Frigidaire and Electrolux French-door and side-by-side refrigerators that use the EPTWFU01 cartridge. Always verify your OEM filter part number against the RWF1181 cross-reference list before purchasing to ensure a proper fit and secure twist-in installation.

What is the micron rating and filtration life of the Tier1 RWF1181?

The Tier1 RWF1181 uses a high-performance coconut shell carbon block media with a 0.5 micron filtration rating, which captures fine sediment and chlorine taste/odor particles. Its rated filtration life is 200 gallons or approximately 6 months of typical household use, whichever comes first. For homes with heavier water consumption or poor incoming water quality, you may need to replace it sooner to maintain optimal flow and filtration performance.

Is the Tier1 RWF1181 NSF/ANSI certified?

Yes. The Tier1 RWF1181 is tested and certified by IAPMO against NSF/ANSI Standard 42 for the reduction of chlorine taste and odor, and material safety. This certification verifies that the filter meets rigorous third-party standards for performance claims and that all components in contact with drinking water are safe. It provides a cost-effective, certified alternative to the OEM EPTWFU01 without sacrificing water quality.

What contaminants does the Tier1 RWF1181 reduce?

The RWF1181's carbon block technology is designed to reduce chlorine taste and odor, sediment, rust particles, cloudiness, and other common aesthetic impurities found in municipal tap water. The 0.5 micron rating ensures fine particulate capture while maintaining adequate flow rate for your fridge's water dispenser and ice maker, delivering cleaner, fresher-tasting water and clearer ice cubes throughout the filter's service life.

How do I install and flush the Tier1 RWF1181 properly?

Installation of the RWF1181 is a simple twist-in process—locate the filter housing inside your Frigidaire refrigerator (typically upper-right interior or base grille), remove the old filter by turning counterclockwise, and insert the new RWF1181 by twisting clockwise until it locks. After installation, flush approximately 2–3 gallons of water through the dispenser to remove carbon fines and air from the system. Then reset your refrigerator's filter status indicator per your owner's manual.
