Product review (4 stars): Manually altered model number from B to E
The filter that came with my dryer already had a torn felt liner. Very disappointed, but I used it anyway and vacuumed the lint area every now and then. I should have immediately glued the felt together but finally, the felt liner was too torn so searched Amazon which listed the same model number but ending in B&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/LG-TROMM-Dryer-Lint-Filter-5231EL1003B/dp/B001DPP2G8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">LG TROMM Dryer Lint Filter 5231EL1003B</a>. I ordered it but then decided I should be rigorous so canceled that order.

I wrote to LG USA to ask for the correct model number. They told me it should be Model E, not B. However, the LG parts distributors they also sent me didn't have any Model E filters on hand. The distributors said that Model B and Model E were interchangeable. I didn't believe them.

I was delighted when Amazon listed Model E so I ordered it. It took maybe nearly a month before Amazon had it to ship to me.

It arrived in an LG plastic bag, but see the photo I uploaded. The model number printed on the label was B but someone crossed it out by hand and wrote in "E." I compared both filters, placed one on top of the other as well as side-by-side. The two filters seemed exactly alike. I put the new filter in the dryer and ran a load through it. It seemed to work fine.

The filter I received, supposedly Model E, is somewhat less expensive than the Model B that Amazon also has listed.
