T.B.
V.~My daughter has asthma and my son is allergic to mold and mildew and he gets croup every year. The allergist has told me that I need to keep the cool mist humidifier in both bedrooms during the fall and winter. Basically when the heat comes on the humidifiers need to be in there. I hope this helps. If you live close to the Clinton Twp. area there is a good children's allergist at the Michigan Institue of Asthma and Allergy. It is located at 19 Mile and Garfield.
