On occasion, indoor moisture producing activities such as clothes drying, cooking, showers, etc., may raise the humidity level higher than it should be, even though the Aprilaire humidifier is not operating. Telltale indications are condensation or frost on cold surfaces such as windows, doors, walls, etc. If such condensation persists for several hours, your home should be ventilated to dissipate the potentially damaging excess moisture.
