Title: Great Product - Very Effective.....
Review: Amazon shines again....! This humidifier has been in constant use for about two weeks now. Performs flawlessly and NOT A TRACE OF WHITE DUST. Two most important issues to ensure proper operation are FIRST - Follow the directions to a "T" and SECOND - Do NOT use SOFTENED water.... iALLERGY was the supplier and their customer service is AWESOME.
