Product review (4 stars): Electrolux Replacement Air Filter
I have never had to use a air filter for a refrigerator, untill getting the Electrolux
I currently have.  This filter does a great job keeping out oders that commonly leak out in refrigerators.
I will use this product again, however, the company I bought it from, sent a filter that was bent, therefore it was hard to slide in.  I will probably use the company as long as their price remains the lowest like this time.
