Whether providing air conditioning or heating, an HVAC system works by drawing air into it, heating or cooling the air and then forcing the air out into the areas requiring heating or cooling through a series of ducts. The interior air of a building is a mixture of human skin particles, microscopic insect droppings, pet dander, pollen, fabric particles, and any other of a wide variety of pollutants.
