Product review (1 stars): DO NOT BUY
I was pleasantly surprised by the cheap price of these filters ($19 for 3 instead of $26 for 1 through Graco). I should have been suspicious, instead. This product is not at all like the Graco filters. After one use, the item became deformed and began to fall apart-the layers started to peel away. I would never recommend this product to anyone.
Rather than continue to pay $26 per filter for the Graco humidifier, I ended up simply buying another humidifier that will be cheaper to maintain. I wish I had researched this Graco humidifier (and filter situation) more before buying it-it turned out to be quite a monetary investment!
