Product review (5 stars): Keep a great refrigerator running--replace filters BUT not too early!
I believe one is told to reorder about a month before the filters are due to be replaced. Filters are supposed to be replaced every 6 months, it says in the manual I received with our 'French'-style Electrolux Refrigerator/Freezer with automatic icemaker and filtered water. It's a great refrig but does need to have filters replaced.
