Bionaire Cool Mist

Cool mist humidifier for medium room sizes from Bionaire Cool Mist with ECC for automatic humidity adjustments.Enhanced by Arm & Hammer baking soda, antimicrobial filter tray resists bacteria growth and foul odors.Electronic control with push-button output selection; runs 30 hours per full water tank.Quieter than other humidifiers; dishwasher-safe tray for cleaning convenience.Humidifier weighs 9 pounds upon shipping; limited warranty.The filters also have a black layer that crumbles all over. Messy. I'm close to trashing it and buying another kind without a filter.
