Electrolux Pure Advantage™ Air and Water Filter Combo (part number ELUXCOMBO) includes 1 Pure Advantage air filter (part number EAFCBF) and 1 Pure Advantage water filter (part number EWF01), so you can replace both at the same time.
The combo fits select Electrolux upright freezers and bottom-freezer and side-by-side refrigerators. Also fits some Frigidaire and Kenmore 253-series bottom-freezer and side-by-side refrigerators.
The air filter removes odors and impurities from the air inside the refrigerator, while the water filter has NSF certifications 42, 53, 372 and 401. The water filter reduces parasites, lead, chlorine taste and odor, volatile organic compounds (VOCs) and some pesticides and pharmaceuticals.
Replace the filters every 6 months or sooner if refrigerator odors become noticeable or if water flow slows.
