Product review (3 stars): Not as I had hoped
Have had various types of humidifiers over the years.  Furnace mounted and free standing ones, and have found that the large floor mounted (cabinet style) ones develop an odor even though our water is such that there is no odor to it nor does it contain the calcium to clog workings.
Had hoped that this product would have more aroma to it than it does.  I am sure that it is doing the chemical control, as advertised, but that is not why I bought it.
