Product review (2 stars): Mold and Mildew
The product description says this filter inhibits the growth of bacteria, mold and mildew. After 2 months of use, it is full of black mold and fuzzy white mildew. I've ordered another, but this time I'll try using a water treatment with it as well. I'm ordering the BestAir 3BT-6 Original BT Humidifier Bacteriostatic Water Treatment - hopefully that will help. If not, next year the Holmes goes in favor of a different model.
