Product review (5 stars): Perfect replacement for my LG Dryer
The felt rim had grown worn on my original lint filter and was allowing excess lint into the dryer ventilation duct - a fact pointed out by the gentleman I paid to clean it out - so I hopped onto Amazon to look for a replacement.

While I periodically scrubbed the mesh on the old filter, fabric softener can and will build up on your lint filter over time, which reduces air flow (and your dryer's efficiency), so I don't think I'm imagining that clothes are also drying slightly faster since I've swapped to this new lint filter.  The replacement filter has vent cutouts on the top (which my original lacked), but it is a perfect fit and functions well with my LG dryer.
