Product review (5 stars): LG Lint Filter
I purchased this lint filter for my LG Model DLE2301W dryer which we purchased in 2010.  The original part # for the lint filter was PS3527578 which cross referenced to 5231EL1003B.  The only difference between this filter and my original filter is that there are 16 small rectangular holes along the top rim of the new filter, which are not on the original filter (see picture).  Maybe this is an improvement to the filter.  Other than this small difference the filter is exactly the same in all other aspects.  The felt seal that runs along the edge of the filter is as thick as the seal on the original.  A few reviewers have complained they received a filter with a thinner felt seal. The filter even came sealed in large zip lock plastic bag which had the "LG" logo on it.  I just finished drying four queen cotton sheets.  They took less time to dry than with the old filter.  We have Amazon Prime the item arrived in the time specified.  I recommend this seller.  Review posted by Tom H.
