With all the scents battling it out in your fridge, you want to neutralize the air, not add another aroma. All natural and non-toxic, this innovative bag is filled with bamboo charcoal to reduce the smells of last week's famers' market. Odor-causing particles get trapped in the tiny charcoal crevices, helping reduce airborne bacteria. To refresh, place the bag in direct sunlight for one hour once a month, and the small pouch can go on fighting for up to two years. Made in China.
