Product review (4 stars): I was a skeptic, now a believer
The hard part about these filters is to tell if they are working....until they are not working! This is the first fridge I have owned with a air filter and although I can not see i work, my nose knows it does. My previous fridges had a stagnant smell but not my LG with these filters. I was a skeptic, now a believer.

The filters were well packaged, arrive fast and fit well. They are more money than they ought to be, however, given the alternative of a foul smelling fridge, the price is acceptable.
