Product review (1 stars): Poor Product
I purchased 4 of these filters earlier this year, and thought I'm make it through this winter and start with one for next.  I'm down ot the last one.  The filters are weak.  They can't stand up by themselves and end up falling down inside the humidifier, and then the fan has no moisture to pull from.  The one that did make it standing up didn't seem to last as long as the others I purchased from Kmart.  After further review, it makes those expensive ones at Kmart or Sears well worth the money.
