Product review (1 stars): These filters are garbage
The filters were already damaged when I received them.  They tried to cram the boxes into another box that was too small.  So the filters were already crumpled and ragged before I even tried to use them.
The filters also got moldy VERY quickly.  I thew out the first one after a week and the 2nd one after 3 weeks.  Complete garbage, don't waste your time.
