Product review (5 stars): Duracraft Humidifier filter AC-809  Great Buy!
I have a perfectly good Duracraft humidifier that needs annual filter replacement because of the hard water in our area.  It was becoming more and more difficult to find the filters, with neither Ace, Lowes, not Home Depot carrying that brand.  The use of this company gave me a great price and reasonable shipping so I can continue to use the humidifier for years to come.
