This page carries two air filters for Electrolux refrigerators: the genuine Electrolux EAFCBF PureAdvantage air filter and a lower-cost Tier1 filter that is a compatible replacement for the EAF1CB. Check your refrigerator manual to confirm which one your model takes.
The air filter's location in an Electrolux fridge depends on the model, so check your refrigerator manual. The manual also shows how to replace it.
Yes, a refrigerator air filter controls odors, so replace it on the schedule in your refrigerator manual. Your water filter is a separate part with its own schedule; for those, see our Electrolux water filters.
