Stop leaving the door open to uninvited pests who enter your home through the furnace duct. In recent years increasing attention and concerns have been drawn to the alarming increase of indoor air pollution in our homes, one of which is the confinement of pollution in our furnace and duct systems.

Pollutants such as pollen, dust, mites, flies, spiders, moths, ants etc. are brought in through the outside air intake to your furnace, whether your furnace is running or not.
