Product review (4 stars): Electrolux refrig air filter
We purchased a 2010 Electrolux wave-touch French-door refrigerator. I have never had a filter in my refrigerator so this was new to me. I notice that it is in the door just opposite of the small ice maker in the upper right of the refrigerator section. My thought that this filter is to help keep the ice fresh from refrigerator odors. My original filter box is solid on one side and you remove a large square of cardboard on the other. I did some looking and have ordered mine from another venue as it was cheaper, but today I noticed with free shipping from several of the Amazon stores the cost is about the same give or take a few pennies. Probably I would not replace as often, but this model tells you it is time to replace...until you do so, the message is there in front of you whenever you get ice or water dispensed outside the refrigerator!

My question is where do you purchase "charcoal paper"? Thanks.
