Just like a charcoal water filter, charcoal briquettes can be used to absorb moisture and odor from the air in your home.
As for how to distribute them, you can simply lay a few out in a metal tray. Other options: sew pouches for them or use an old sock, then hang them in inconspicuous areas. Line a basket with foil or plastic and lay the briquettes inside. Or simply set them out on a tray on a shelf or side table: the black little pillows actually look kind of cool!
Be sure to get natural briquettes without mesquite or easy-light additives.
