Replace your filter twice a season for optimum performance based on usage. Be sure not to over-humidify. Cold air is not able to hold as much moisture as warm air. Cold drafts seeping through windows and doors could cause water vapor to condense at these points of entry. If your home is well insulated and weather stripped, but lacks effective vapor barriers, water may seep through the ceilings and walls. Moisture may condense in the attic, inside or outside of the walls. Humidity levels should be reduced before water damage occurs, if you notice any of these moisture related conditions.
