This is a great product to have on hand to cut down the smell from dirty diapers. You put it in the bottom of your diaper pail and the charcoal absorbs the odor created. Once per month you need to sit in the sun to reactive it, but it continues to work like a charm. I've noticed a large difference from when I wasn't using it until now. At $4.99 at baby stores it's not a bad deal.
