| Millions of tiny but nasty critters may be lurking inside the ductwork of your home's heating and cooling system. These measly contaminants can include dust, pollen, bacteria, mold and fungal spores, dust mites, tobacco smoke by-products, and animal dander. Too small to be captured by your furnace filter, these invisible invaders can spew out into the air you and your family breathe every time the furnace or air conditioner runs wreaking havoc on the lungs, sinuses and the health of your family. |
