ClearChoice Replacement for ULTRAWF Refrigerator Water Filter & PAULTRA Air Filter

(1) ClearChoice CLCH121 Refrigerator Water Filter - replaces Frigidaire ULTRAWF
(1) AIRX FAF001 Refrigerator Air Filter - replaces Frigidaire PAULTRA

The ClearChoice CLCH121 is a compatible filter replacement for the Frigidaire ULTRAWF - AKA PureSource Ultra.  It fits refrigerators from Frigidaire, Electrolux, Kenmore, and others.  This filter uses its activated carbon technology to deliver healthier and refreshing water and ice. The CLCH121 needs to be changed every six months or 300 gallons (whichever comes first).  The AIRX FAF001 Refrigerator Air Filter eliminates foul odors from your refrigerator and freezer.


  • Replacement filter for part number ULTRAWF, 46-9999 and more
  • Easy installation - just slide it in and push until you hear a "click"
  • Can be used in Sears, Frigidaire, and Kenmore refrigerators
  • Made with pride in the USA

Activated Block Carbon Technology

The CLCH121-COMBO uses activated block carbon technology. Carbon is one of the most adsorptive substances, and its numerous and microscopic pores make it capable of adsorbing many microscopic contaminants. Adsorption is a chemical bond between the surface of the carbon and a molecule (contaminant).

  • Activated carbon is a carbonaceous, highly porous adsorptive medium that has a complex structure composed primarily of carbon atoms. The networks of pores in activated carbons are channels created within a rigid skeleton of disordered layers of carbon atoms, linked together by chemical bonds, stacked unevenly, creating a highly porous structure between the carbon layers. Activated carbon is able to attract and capture a whole host of contaminants, including chlorine and other organic chemical compounds. 
  • Activated carbon means that the carbon has been treated at 1000°C with steam molecules to selectively burn holes into the carbonized raw material, creating a multitude of pores inside the carbonaceous matrix. This process creates so much surface area that a teaspoon of activated carbon has roughly the same surface area as a soccer field! 
  • Activated block carbon, then, with its use of adsorption, is one of the most effective water filtration methods in use today.
