Water is dispersed evenly throughout a Vapor Pad® inside the 1099LHS. A portion of the heated air from the furnace passes through the water-soaked pad where it absorbs additional moisture and then returns for distribution throughout your home. Newly-moistened and healthier air is provided to you and your family.
