    Besides being a bit noisy it is a very good humidifier. Perhaps it's just this unit? I'll have to contact Aprilaire to find out I guess.

    Used in an air conditioned basement with constant humidity ~55%. Set up as a free standing device. Dropped humidity to ~40% and dramatically improved comfort in 48 hrs. ‘Merica!
