Product review (5 stars): Looks like and exact  LG replacement filter
Although the supplied filter has no discernible manufactures mark, as far as I'm concerned it is an exact replacement.  The only marking I can see on the LG filter I removed from my fridge and the replacement filter is the word "FRONT" on the edge in two places.  LG suggest replacing this filter when the air filter alarm is displayed or every six month. These filters definitely trap odors.  I'll keep buying this filter from Amazon as long as they are sold at this very competitive price.
