What makes an EPA-certified wood stove burn cleaner than a non-certified wood stove?
When wood is not completely burned, a complex mixture of gases and particles – wood smoke – is created. Because EPA-certified wood stoves are designed with better insulation and improved air flow, more of these gases and particles are burned inside the stove, resulting in less smoke. In most cases, you will see no visible emissions from the chimney, and you will smell less smoke from a properly installed EPA-certified stove.
