Product review (5 stars): Refrigertor Air Filter
I purchased several of these filters because Frigidaire recommends changing the filter and the refrigerator has  a light programmed for a certain time.  The filters arrived in several days undamaged and at a bulk price that was lower than stores.  Plus, stores that stock the filters are hard to find, making more online purchase easier and less expensive due to the price of fuel.
Pros: Lower in overall cost, timely delivery
Cons: None
