Humidity control is an important part of allergen control. One allergen -  Mold thrives  in high humidity but is dormant or dies when the humidity is low.  Lowered humidity also takes care of mildew odor as well.  Another allergen - dust mites also die when the humidity stays below 50%. These two nasty allergens can be effectively controlled in the air with dehumidifiers but remember, the dust mites in your bed rely on you for their source of humidity, so mattresses, pillows and box springs should also be encased.
