Product review (5 stars): BestAir 3BT-6 Original BT Humidifier Bacteriostatic Water Treatment
I was very pleased to find this product.  During the winter months, when the air is so dry I keep two humidifiers in the house.  One beside the grand piano and the other in my bedroom. In the past I've had problems with "growth" and this product eliminated this problem completely!  I would highly recommende this to anyone with a humidifier!
