With the dry heat of the wood stove we're constantly running two humidifiers to keep the air moist the house. Not to mention the cooking pot full of water on top of the wood stove. And now we're pretty much comfortable like this. During the summer months we used to run a big multi layered filtered air purifier. But after seeing so many commercials on T.V. about the Oreck xl pro air purifier that were factory reconditioned at half price we bought one and it's so much more efficient than our old one.
