Models LAD1814 and LAD-2214 are designed to complement both newer high efficiency systems as well as existing equipment.

The LAD electrostatic whole house air purifier features a free flow low pressure drop design. This design means less airflow reduction than most media filters. Not only is there less pressure drop it also does a better job at cleaning the air in your home. The LAD1814 helps  eliminate hot  and cols cold spots through out your home. The rugged construction of LAD models, like the entire LakeAir line, assures you of peak performance year after year. This model is airflow switch equipped.
