Product review (1 stars): The Filters Smell Musty.
I have bought these filters for over 15 years.  I used to buy them locally until a couple of years ago I found them on Amazon.  I have reviewed this filter a year ago 5 star but I am changing my review today because the recent filters were unuseable. These filters don't last but a couple of weeks.  It seems they don't get wet all the way.  During the two weeks that I used them I noticed musty smell coming out of the humidifier.  I was afraid that mildew was growing in the filters.  I tossed the filters and I bought a new set this time I also bought Bacteriostat Solution and followed the instruction to no avail.  I am very disappointed with how Vornado and Amazon selling an inferior product.  One more item is the fit  a bit tight.  I now have couple of these humidifiers with no filter.
