W.--We had the same problem when we moved into our home. It was owned by little old people and although the house wasn't abused, it wasn't cleaned very often. We purchased an air purifier from EcoQuest International. It's a purifier not an air cleaner. It's a unit that you can run continuously and on occasion set it on a higher setting while you are out of the house and it will definitely get rid of that odor. We have a friend who bought a used car from a smoker and it was the only thing that got rid of the odor. If you would like more information on how to get one, please contact my husband at ____@____.com are a little pricey, but they are definitely worth it. My house is a A LOT less dusty and I am a severe airborne allergy sufferer and it has helped so much. You are welcome to contact me as well. D.
