Should my home be humidified?

That depends largely on your climate and personal comfort needs.  Humidification is definitely helpful in many homes and businesses.  Particularly during cold weather, insufficient moisture in the air often is responsible for such assorted problems such as stuffy noses, sore throats, even more dust than usual, cracks and dried-out joints in wood furniture, wilted plants, and static electricity which jolts hair, clothes, and computer disks.  Indoor relative humidity may fall to around 7 percent, which is much drier than the 25 percent relative humidity of the Sahara Desert!  Ideal indoor relative humidity is between 30 to 50 percent.
