Product review (4 stars): Works as expected, make sure to clean them
These worked perfect in the Vornado but be sure to remove and clean them otherwise they will mold.  Used around 60 days without any issue but when I went to put the unit away for the Summer I found black mold on the filters which surprised me and worries me a little.  They fit fine and did the job but I know to pull them out and clean them every few weeks.
