Product review (4 stars): Clean filter regularly and save energy!
I bought this to replace my lint filter that had a seal on it and the seal was coming up.  Without the seal, it cause lint to get sucked into the venting system.  This one didn't have a seal, but it seems to work much better than the old worn out lint trap.  It is the replacement model for the one with a seal.  I was hesitant that it would not work as well without the seal, but it is doing a much better job than my old worn out lint trap, so what more can I ask for???
