Product review (5 stars): EXCELLENT PRODUCT
THIS FILTER IS GREAT.  THE ONE THAT CAME WITH THE HUMIDIFIER HAD NO BLUE COVER ON IT AND IT WAS AWFUL.  THIS ONE DOES NOT HAVE TO BE RE-WET CONSTANTLY AND IT DOESN'T TURN BROWN.  I RECEIVED IT ON TIME AND THE PRICE WAS GOOD.  I AM VERY HAPPY WITH THIS FILTER.
