Product review (1 stars): For the love of all that is good in the world, DO NOT BUY THIS!
Absolutely horrendous product!  This is two thin pieces of wick with a piece of supporting foil in the middle.  The OEM version is one solid piece.  This does not work nearly as well and it only took two weeks for it to fall apart, detach itself from the supporting foil, into a clump resembling a torn apart wet paper towel.  Even worse, this is only a dollar or two less than the OEM filter, which typically lasts me all winter.
