Charcoal The Air Cleaner

I have seen a number of my agents get good results from buying a large bag of generic, cheap, charcoal briquettes and putting it in homes that have dank, musky smells. Just put a bag in the rooms with the problem.  Place the bag lying down on its back, having the front facing the ceiling. Cut a cross on the upwards facing side and fold flaps open. In a day or so the room will be much fresher. And when you are done using it for this purpose use it to cook with for the next bbq.
