Product review (5 stars): Exact same product but cheaper than buying via retailers
This is the same Frigidaire refrigerator air filter that came with our fridge.  The "PAULTRA" code on the box is how we match it up to the original filter.  Will be reordering from Amazon in the future.  Works great.  Tip:  We use a sharpie pen and write the date on the side of the filter, so we can flip open the filter "door" and read the date we installed it.
