Product review (2 stars): SIMPLY THE WORST EVER!!
Vornado...PLEASE MAKE YOUR FILTERS THE WAY THEY USED TO BE MADE.  THESE THINGS GET BROWN AND CRUNCHY AFTER A COUPLE OF DAYS.  IN A COUPLE OF WEEKS, THEY START FALLING APART.  SOAKING THEM IN VINEGAR DOES NO GOOD WHATSOEVER - I'VE TRIED AGAIN AND AGAIN.  SOAKING THEM IN A TEASPOON OF BLEACH CAUSES THEM TO FALL APART.  THEY LAST FOR ABOUT TWO WEEKS TOPS.  THE OLD STYLE LASTED AT LEAST SIX TO TEN WEEKS!!  IF THEY AREN'T BETTER NEXT YEAR, I PLAN TO THROW MY NEW THIS YEAR, VORNADO HUMIDIFIER AWAY AND FIND A BRAND THAT DOES NOT HAVE FILTERS OR ONE THAT HAS FILTERS THAT ARE WELL MADE AND LAST MORE THAN A FEW MINUTES!!  I'VE BEEN BUYING VORNADO HUMIDIFIERS SINCE 1995, BUT THESE HORRIBLE FILTERS THAT MUST BE USED ARE SENDING ME TO ANOTHER BRAND.
